The state of European politics
In the 15th century, changes in the structure of European polity, accompanied by a new intellectual temper, suggested to such observers as the philosopher and clerical statesman Nicholas of Cusa that the “Middle Age” had attained its conclusion and a new era had begun. The Papacy, the symbol of the spiritual unity of Christendom, lost much of its prestige in the Great Western Schism and the conciliar movement and became infected with the lay ideals prevailing in the Italian peninsula. In the 16th century, the Protestant Reformation reacted against the worldliness and corruption of the Holy See, and the Roman Catholic church responded in its turn by a revival of piety known as the Counter-Reformation. While the forces that were to erupt in the Protestant movement were gathering strength, the narrow horizons of the Old World were widened by the expansion of Europe to America and the East. (This section treats the political, diplomatic, and military history of Europe from the Reformation to the Peace of Westphalia. For a discussion of the religious history of this period, see Christianity, Protestantism, and Roman Catholicism. The expansion of European culture to new lands is covered in colonialism.)
In western Europe, nation-states emerged under the aegis of strong monarchical governments, breaking down local immunities and destroying the unity of the European respublica Christiana. Centralized bureaucracy came to replace medieval government. Underlying economic changes affected social stability. Secular values prevailed in politics, and the concept of a balance of power came to dominate international relations. Diplomacy and warfare were conducted by new methods. Permanent embassies were accredited between sovereigns, and on the battlefield standing armies of professional and mercenary soldiers took the place of the feudal array that had reflected the social structure of the past. At the same time, scientific discoveries cast doubt on the traditional cosmology. The systems of Aristotle and Ptolemy, which had long been sanctified by clerical approval, were undermined by Copernicus, Mercator, Galileo, and Kepler.
In the Iberian Peninsula the impetus of the counteroffensive against the Moors carried the Portuguese to probe the West African coastline and the Spanish to attempt the expulsion of Islām from the western Mediterranean. In the last years of the 15th century, Portuguese navigators established the sea route to India and within a decade had secured control of the trade routes in the Indian Ocean and its approaches. Mercantile interests, crusading and missionary zeal, and scientific curiosity were intermingled as the motives for this epic achievement. Similar hopes inspired Spanish exploitation of the discovery by Christopher Columbus of the Caribbean outposts of the American continent in 1492. The Treaties of Tordesillas and Saragossa in 1494 and 1529 defined the limits of westward Spanish exploration and the eastern ventures of Portugal. The two states acting as the vanguard of the expansion of Europe had thus divided the newly discovered sea lanes of the world between them.
By the time of the Treaty of Saragossa, when Portugal secured the exclusion of Spain from the East Indies, Spain had begun the conquest of Central and South America. In 1519, the year in which Ferdinand Magellan embarked on the westward circumnavigation of the globe, Hernán Cortés launched his expedition against Mexico. The seizure of Peru by Francisco Pizarro and the enforcement of Portuguese claims to Brazil completed the major steps in the Iberian occupation of the continent. By the middle of the century, the age of the conquistadores was replaced by an era of colonization, based both on the procurement of precious metal by Indian labour and on pastoral and plantation economies using imported African slaves. The influx of bullion into Europe became significant in the late 1520s, and from about 1550 it began to produce a profound effect upon the economy of the Old World.
Nation-states and dynastic rivalries
The organization of expansion overseas reflected in economic terms the political nationalism of the European states. This political development took place through processes of internal unification and the abolition of local privileges by the centralizing force of dynastic monarchies. In Spain the union of Aragon, Valencia, and Catalonia under John II of Aragon was extended to association with Castile through the marriage of his son Ferdinand with the Castilian heiress Isabella. The alliance grew toward union after the accession of the two sovereigns to their thrones in 1479 and 1474, respectively, and with joint action against the Moors of Granada, the French in Italy, and the independent kingdom of Navarre. Yet, at the same time, provincial institutions long survived the dynastic union, and the representative assembly (Cortes) of Aragon continued to cling to its privileges when its Castilian counterpart had ceased to play any effective part. Castilian interest in the New World and Aragonese ties in Italy, moreover, resulted in the ambivalent nature of Spanish 16th-century policy, with its uneasy alternation between the Mediterranean and the Atlantic. The monarchy increased the central power by the absorption of military orders and the adaptation of the Hermandad, or police organization, and the Inquisition for political purposes. During the reign of Charles I (the emperor Charles V) centralization was quickened by the importation of Burgundian conciliar methods of government, and in the reign of his son Philip II Spain was in practice an autocracy.
Other European monarchies imitated the system devised by Roman-law jurists and administrators in the Burgundian dominions along the eastern borders of France. In England and France the Hundred Years' War (conventionally 1337–1453) had reduced the strength of the aristocracies, the principal opponents of monarchical authority. The pursuit of strong, efficient government by the Tudors in England, following the example of their Yorkist predecessors, found a parallel in France under Louis XI and Francis I. In both countries revision of the administrative and judicial system proceeded through conciliar institutions, although in neither case did it result in the unification of different systems of law. A rising class of professional administrators came to fulfill the role of the king's executive. The creation of a central treasury under Francis I brought an order into French finances already achieved in England through Henry VII's adaptation of the machinery of the royal household. Henry VIII's minister, Thomas Cromwell, introduced an aspect of modernity into English fiscal administration by the creation of courts of revenue on bureaucratic lines. In both countries, the monarchy extended its influence over the government of the church. The unrestricted ability to make law was established by the English crown in partnership with Parliament. In France the representative Estates-General lost its authority, and sovereignty reposed in the king in council. Supreme courts (parlements) possessing the right to register royal edicts imposed a slight and ineffective limitation on the absolutism of the Valois kings. The most able exponent of the reform of the judicial machinery of the French monarch was Charles IX's chancellor, Michel de L'Hôpital, but his reforms in the 1560s were frustrated by the anarchy of the religious wars. In France the middle class aspired to ennoblement in the royal administration and mortgaged their future to the monarchy by investment in office and the royal finances. In England, on the other hand, a greater flexibility in social relations was preserved, and the middle class engaged in bolder commercial and industrial ventures.
Territorial unity under the French crown was attained through the recovery of feudal appanages (alienated to cadet branches of the royal dynasty) and, as in Spain, through marriage alliances. Brittany was regained in this way, although the first of the three Valois marriages with Breton heiresses also set in train the dynastic rivalry of Valois and Habsburg. When Charles VIII of France married Anne of Brittany, he stole the bride of the Austrian archduke and future emperor Maximilian I and also broke his own engagement to Margaret of Austria, Maximilian's daughter by Mary of Burgundy. Margaret's brother Philip, however, married Joan, heiress of Castile and Aragon, so that their son eventually inherited not only Habsburg Germany and the Burgundian Netherlands but also Spain, Spanish Italy, and America. The dominions of Charles V thus encircled France and incorporated the wealth of Spain overseas. Even after the division of this vast inheritance between his son, Philip II of Spain, and his brother, the emperor Ferdinand I, the conflict between the Habsburgs and the French crown dominated the diplomacy of Europe for more than a century.
The principal dynastic conflict of the age was less unequal than it seemed, for the greater resources of Charles V were offset by their cumbrous disunity and by local independence. In the Low Countries he was able to complete the Seventeen Provinces by new acquisitions, but, although the coordinating machinery of the Burgundian dukes remained in formal existence, Charles's regents were obliged to respect local privileges and to act through constitutional forms. In Germany, where his grandfather Maximilian I had unsuccessfully tried to reform the constitution of the Holy Roman Empire, Charles V could do little to overcome the independence of the lay and ecclesiastical princes, the imperial knights, and the free cities. The revolts of the knights (1522) and the peasantry (1525), together with the political disaggregation imposed by the Reformation, rendered the empire a source of weakness. Even in Spain, where the rebellion of the comuneros took place in 1520–21, his authority was sometimes flouted. His allies, England and the papacy, at times supported France to procure their own profit. France, for its part, possessed the advantages of internal lines of communication and a relatively compact territory, while its alliance with the Ottoman Empire maintained pressure on the Habsburg defenses in southeast Europe and the Mediterranean. Francis I, however, like his predecessors Charles VIII and Louis XII, made the strategic error of wasting his strength in Italy, where the major campaigns were fought in the first half of the century. Only under Henry II was it appreciated that the most suitable area for French expansion lay toward the Rhine.
Turkey and eastern Europe
A contemporary who rivaled the power and prestige of Francis I and Charles V was the ruler of the Ottoman Empire, the sultan Süleyman I the Magnificent (1520–66). With their infantry corps d'élite (the Janissaries), their artillery, and their cavalry, or sipahis, the Ottomans were the foremost military power in Europe, and it was fortunate for their Christian adversaries that Eastern preoccupations prevented them from taking full advantage of Western disunity. A counterpoise was provided by the rise of the powerful military order of the Ṣafavids in Persia—hostile to the orthodox Ottomans through their acceptance of the heretical Islāmic cult of the Shīʿites. Ottoman strength was further dissipated by the need to enforce the allegiance of Turkmen begs in Anatolia and of the chieftains of the Caucasus and Kurdistan and to maintain the conquest of the sultanate of Syria and Egypt by Süleyman's predecessor, Selim I. Süleyman himself overran Iraq and even challenged Portuguese dominion of the Indian Ocean from his bases in Suez and Basra. The Crimean Tatars acknowledged his suzerainty, as did the corsair powers of Algiers, Tunis, and Tripoli. His armies conquered Hungary in 1526 and threatened Vienna in 1529. With the expansion of his authority along the North African coast and the Adriatic littoral, it seemed for a time as if the Mediterranean, like the Black Sea and the Aegean, might become an Ottoman lake.
Though it observed the forms of an Islāmic legal code, Turkish rule was an unlimited despotism, suffering from none of the financial and constitutional weaknesses of Western states. With its disciplined standing army and its tributary populations, the Ottoman Empire feared no internal threat except during the periods of disputed succession, which continued to occur despite a law empowering the reigning sultan to put to death collateral heirs. It was not unusual for the sultan to content himself with the overlordship of frontier provinces. Moldavia and Walachia were for a time held in this fashion, and in Transylvania the vaivode John Zápolya gladly accepted Süleyman as his master in return for support against Ferdinand of Austria.
Despite the expeditions of Charles V against Algiers and Tunis, and the inspired resistance of Venice and Genoa in the war of 1537–40, the Ottomans retained the initiative in the Mediterranean until several years after the death of Süleyman. The Knights of St. John were driven from Rhodes and Tripoli and barely succeeded in retaining Malta. Even after Spain, the papacy, Venice, and Genoa had crushed the Turkish armament in 1571 in the Battle of Lepanto, the Ottomans took Cyprus and recovered Tunis from the garrison installed by the allied commander, Don John of Austria. North Africa remained an outpost of Islām and its corsairs continued to harry Christian shipping, but the Ottoman Empire did not again threaten Europe by land and sea until late in the 17th century.
Poland, Lithuania, Bohemia, and Hungary were all loosely associated at the close of the 15th century under rulers of the Jagiellon dynasty. In 1569, three years before the death of the last Jagiellon king of Lithuania-Poland, these two countries merged their separate institutions by the Union of Lublin. Thereafter the Polish nobility and the Roman Catholic faith dominated the Orthodox lands of Lithuania and held the frontiers against Muscovy, the Cossacks, and the Tatars. Bohemia and the vestiges of independent Hungary were regained by the Habsburgs as a result of dynastic marriages, which the emperor Maximilian I planned as successfully in the east as he did in the west. When Louis II of Hungary died fighting the Ottomans at Mohács in 1526, Archduke Ferdinand of Austria obtained both crowns and endeavoured to affirm the hereditary authority of his dynasty against aristocratic insistence on the principle of election. In 1619, Habsburg claims in Bohemia became the ostensible cause of the Thirty Years' War, when the Diet of Prague momentarily succeeded in deposing Ferdinand II.
In the 16th century, eastern Europe displayed the opposite tendency to the advance of princely absolutism in the West. West of the Carpathians and in the lands drained by the Vistula and the Dnestr, the landowning class achieved a political independence that weakened the power of monarchy. The towns entered a period of decline, and the propertied class, though divided by rivalry between the magnates and the lesser gentry, everywhere reduced their peasantry to servitude. In Poland and Bohemia the peasants were reduced to serfdom in 1493 and 1497, respectively, and in free Hungary the last peasant rights were suppressed after the rising of 1514. The gentry, or szlachta, controlled Polish policy in the Sejm (parliament), and, when the first Vasa king, Sigismund III, tried to reassert the authority of the crown after his election in 1587, the opportunity had passed. Yet, despite the anarchic quality of Polish politics, the aristocracy maintained and even extended the boundaries of the state. In 1525 they compelled the submission of the secularized Teutonic Order in East Prussia, resisted the pressure of Muscovy, and pressed to the southeast, where communications with the Black Sea had been closed by the Ottomans and their tributaries.
Farther to the east the grand principality of Moscow emerged as a new and powerful despotism. Muscovy, and not Poland, became the heir to Kiev during the reign of Ivan III the Great in the second half of the 15th century. By his marriage with the Byzantine princess Sofia (Zoë) Palaeologus, Ivan also laid claim to the traditions of Constantinople. His capture of Novgorod and repudiation of Tatar overlordship began a movement of Muscovite expansion, which was continued by the seizure of Smolensk by his son Vasily (Basil) III and by the campaigns of his grandson Ivan IV the Terrible (1533–84). The latter destroyed the khanates of Kazan and Astrakhan and reached the Baltic by his conquest of Livonia from Poland and the Knights of the Sword. He was the first to use the title of tsar, and his arbitrary exercise of power was more ruthless and less predictable than that of the Ottoman sultan. After his death Muscovy was engulfed in the Time of Troubles, when Polish, Swedish, and Cossack armies devastated the land. The accession of the Romanov dynasty in 1613 heralded a period of gradual recovery. Except for occasional embassies, the importation of a few Western artisans, and the reception of Tudor trading missions, Muscovy remained isolated from the West. Despite its relationship with Greek civilization, it knew nothing of the Renaissance. Though it experienced a schism within its own Orthodox faith, it was equally untouched by Reformation and Counter-Reformation, the consequences of which convulsed western Europe in the late 16th century.
The war originated with dual crises at the continent's centre: one in the Rhineland and the other in Bohemia, both part of the Holy Roman Empire.
“The dear old Holy Roman Empire, How does it stay together?”
asked the tavern drinkers in Goethe's
Faust—and the answer is no easier to find today than in the late 18th, or early 17th, century. The Holy Roman Empire of the German Nation was a land of many polities. In the empire there were some 1,000 separate, semiautonomous political units, many of them very small—such as the Imperial Knights, direct vassals of the emperor and particularly numerous in the southwest, who might each own only part of one village—and others comparable in size with smaller independent states elsewhere, such as Scotland or the Dutch Republic. At the top came the lands of the Austrian
Habsburgs, covering the elective kingdoms of
Bohemia and
Hungary, as well as
Austria, the
Tyrol, and
Alsace, with about 8,000,000 inhabitants; next came electoral
Saxony,
Brandenburg, and
Bavaria, with more than 1,000,000 subjects each; and then the
Palatinate,
Hesse,
Trier, and
Württemberg, with about 500,000 each.
These were large polities, indeed, but they were weakened by three factors. First, they did not accept primogeniture: Hesse had been divided into four portions at the death of Landgrave Philip the Magnanimous, Luther's patron, in 1567; the lands of the Austrian Habsburgs were partitioned in 1564 and again in 1576. Second, many of the states were geographically fragmented: thus the Palatinate was divided into an Upper County, adjoining the borders of both Bohemia and Bavaria, and a Lower County, on the middle Rhine. These factors had, in the course of time, created in Germany a balance of power between the states. The territorial strength of the Habsburgs may have brought them a monopoly of the imperial title from 1438 onward, but they could do no more: the other princes, when threatened, were able to form alliances whose military strength was equal to that of the emperor himself. However, the third weakness—the religious upheaval of the 16th century—changed all that: princes who had formerly stood together were now divided by religion. Swabia, for example, more or less equal in area to modern Switzerland, included 68 secular and 40 spiritual princes and also 32 imperial free cities. By 1618 more than half of these rulers and almost exactly half of the population were Catholic; the rest were Protestant. Neither bloc was prepared to let the other mobilize an army. Similar paralysis was to be found in most other regions: the Reformation and Counter-Reformation had separated Germany into hostile but evenly balanced confessional camps.
The Religious Peace of Augsburg in 1555 had put an end to 30 years of sporadic confessional warfare in Germany between Catholics and Lutherans by creating a layered structure of legal securities for the people of the empire. At the top was the right (known as cuius regio, eius religio) of every secular ruler, from the seven electors down to the imperial knights, to dictate whether their subjects' religion was to be Lutheran or Catholic (the only officially permitted creeds). The only exceptions to this rule were the imperial free cities, where both Lutherans and Catholics were to enjoy freedom of worship, and the Catholic ecclesiastical states, where bishops and abbots who wished to become Lutherans were obliged to resign first. The latter provision, known as the reservatum ecclesiasticum, gave rise to a war in 1583–88 when the archbishop of Cologne declared himself a Protestant but refused to resign: in the end a coalition of Catholic princes, led by the duke of Bavaria, forced him out.
This “War of Cologne” was a turning point in the religious history of Germany. Until then, the Catholics had been on the defensive, losing ground steadily to the Protestants. Even the decrees of the Council of Trent, which animated Catholics elsewhere, failed to strengthen the position of the Roman church in Germany. After the successful struggle to retain Cologne, however, Catholic princes began to enforce the cuius regio principle with rigour. In Bavaria, as well as in Würzburg, Bamberg, and other ecclesiastical states, Protestants were given the choice of either conversion or exile. Most of those affected were adherents of the Lutheran church, already weakened by defections to Calvinism, a new creed that had scarcely a German adherent at the time of the Religious Peace of Augsburg. The rulers of the Palatinate (1560), Nassau (1578), Hesse-Kassel (1603), and Brandenburg (1613) all abandoned Lutheranism for the new confession, as did many lesser rulers and several towns. Small wonder that the Lutherans came to detest the Calvinists even more than they loathed the Catholics.
These religious divisions created a complex confessional pattern in Germany. By the first decade of the 17th century, the Catholics were firmly entrenched south of the Danube and the Lutherans northeast of the Elbe; but the areas in between were a patchwork quilt of Calvinist, Lutheran, and Catholic, and in some places one could find all three. One such was Donauwörth, an independent city just across the Danube from Bavaria, obliged (by the Peace of Augsburg) to tolerate both Catholics and Protestants. But for years the Catholic minority had not been permitted full rights of public worship. When in 1606 the priests tried to hold a procession through the streets, they were beaten and their relics and banners were desecrated. Shortly afterward, an Italian Capuchin, Fray Lorenzo da Brindisi, later canonized, arrived in the city and was himself mobbed by a Lutheran crowd chanting “Capuchin, Capuchin, scum, scum.” He heard from the local clergy of their plight and promised to find redress. Within a year, Fray Lorenzo had secured promises of aid from Duke Maximilian of Bavaria and Emperor Rudolf II. When the Lutheran magistrates of Donauwörth flatly refused to permit their Catholic subjects freedom of worship, the Bavarians marched into the city and restored Catholic worship by force (December 1607). Maximilian's men also banned Protestant worship and set up an occupation government that eventually transferred the city to direct Bavarian rule.
These dramatic events thoroughly alarmed Protestants elsewhere in Germany. Was this, they wondered, the first step in a new Catholic offensive against heresy? Elector Frederick IV of the Palatinate took the lead. On May 14, 1608, he formed the Evangelical, or Protestant, Union, an association to last for 10 years, for self-defense. At first, membership remained restricted to Germany, although the elector's leading adviser, Christian of Anhalt, wished to extend it, but before long a new crisis rocked the empire and turned the German union into a Protestant International.
The new crisis began with the death of John William, the childless duke of Cleves-Jülich, in March 1609. His duchies, occupying a strategic position in the Lower Rhineland, had both Protestant and Catholic subjects, but both of the main claimants to the inheritance were Protestants; under the cuius regio principle, their succession would lead to the expulsion of the Catholics. The emperor therefore refused to recognize the Protestant princes' claim. Since both were members of the Union, they solicited, and received, promises of military aid from their colleagues; they also received, via Christian of Anhalt, similar promises from the kings of France and England. This sudden accretion in Protestant strength caused the German Catholics to take countermeasures: a Catholic League was formed between Duke Maximilian of Bavaria and his neighbours on July 10, 1609, soon to be joined by the ecclesiastical rulers of the Rhineland and receiving support from Spain and the Papacy. Again, reinforcement for one side provoked countermeasures. The Union leaders signed a defensive treaty with England in 1612 (cemented by the marriage of the Union's director, the young Frederick V of the Palatine, to the king of England's daughter) and with the Dutch Republic in 1613.
At first sight, this resembles the pyramid of alliances, patiently constructed by the statesmen of Europe 300 years later, which plunged the continent into World War I. But whereas the motive of diplomats before 1914 was fear of political domination, before 1618 it was fear of religious extirpation. The Union members were convinced of the existence of a Catholic conspiracy aimed at rooting out all traces of Protestantism from the empire. This view was shared by the Union's foreign supporters. At the time of the Cleves-Jülich succession crisis, Sir Ralph Winwood, an English diplomat at the heart of affairs, wrote to his masters that, although “the issue of this whole business, if slightly considered, may seem trivial and ordinary,” in reality its outcome would “uphold or cast down the greatness of the house of Austria and the church of Rome in these quarters.” Such fears were probably unjustified at this time. In 1609 the unity of purpose between pope and emperor was in fact far from perfect, and the last thing Maximilian of Bavaria wished to see was Habsburg participation in the League: rather than suffer it, in 1614 he formed a separate association of his own and in 1616 he resigned from the League altogether. This reduction in the Catholic threat was enough to produce reciprocal moves among the Protestants. Although there was renewed fighting in 1614 over Cleves-Jülich, the members of the Protestant Union had abandoned their militant stance by 1618, when the treaty of alliance came up for renewal. They declared that they would no longer become involved in the territorial wrangles of individual members, and they resolved to prolong their association for only three years more.
Although, to some extent, war came to Germany after 1618 because of the existence of these militant confessional alliances, the continuity must not be exaggerated. Both Union and League were the products of fear; but the grounds for fear seemed to be receding. The English ambassador in Turin, Isaac Wake, was sanguine: “The gates of Janus have been shut,” he exulted in late 1617, promising “calm and Halcyonian days not only unto the inhabitants of this province of Italye, but to the greatest part of Christendome.” That Wake was so soon proved wrong was due largely to events in the lands of the Austrian Habsburgs over the winter of 1617–18.
The crisis in the Habsburg lands
While the Cleves-Jülich crisis held the attention of western Europe in 1609, the eyes of observers farther east were on Prague, the capital of Bohemia. That elective kingdom (which also included Silesia, Lusatia, and Moravia), together with Hungary, had come to the Habsburg family in 1526. At first they were ruled jointly with Austria by Ferdinand I (brother of Emperor Charles V), but after his death in 1564 the inheritance was divided into three portions: Alsace and Tyrol (known as “Further Austria”) went to one of his younger sons; Styria, Carinthia, and Carniola (known as “Inner Austria”) went to a second; only the remainder was left for his successor as emperor, Maximilian II.
By 1609 fragmentation had advanced even further: Maximilian's eldest son, Rudolf II (emperor, 1576–1611), ruled only Bohemia; all the rest of his father's territories had been acquired, the previous year, by a younger son, Matthias. The new ruler had come to power not through strength or talent, however, but by the exploitation of the religious divisions of his subjects. During the 1570s the Protestants of Austria, Bohemia, and Hungary had used their strength of numbers and control of local representative assemblies to force the Habsburgs to grant freedom of worship to their Protestant subjects. This was clearly against the cuius regio principle, and everyone knew it. In 1599 the ruler of Inner Austria, Archduke Ferdinand, began a campaign of forcible re-Catholicization among his subjects, which proved entirely successful. But, when Rudolf II launched the same policy in Hungary shortly afterward, there was a revolt, and the rebels offered the Hungarian crown to Matthias in return for guarantees of toleration. The Bohemians decided to exploit Rudolf's temporary embarrassment by pressing him to grant similarly far-reaching concessions to the non-Catholic majority of that kingdom. The “Letter of Majesty” (Majestätsbrief) signed by Rudolf on July 9, 1609, granted full toleration to Protestants and created a standing committee of the Estates, known as “the Defensors,” to ensure that the settlement would be respected.
Rudolf II—a recluse who hid in a world of fantasy and alchemy in his Hradčany palace above Prague, a manic depressive who tried to take his own life on at least one occasion—proved to be incapable of keeping to the same policy for long. In 1611 he tried to revoke the Letter of Majesty and to depose the Defensors by sending a small Habsburg army into Prague, but a force of superior strength was mobilized against the invaders and the Estates resolved to depose Rudolf and offer their crown to Matthias. The emperor, broken in mind and body, died in January 1612. All his territories were then ruled by his brother, who also succeeded him as Holy Roman emperor later in the year. The alliance with the Protestant Estates that brought about Matthias's elevation, however, did not long continue once he was in power. The new ruler sought to undo the concessions he had made, and he looked for support to his closest Habsburg relatives: his brother Albert, ruler of the Spanish Netherlands; his cousin Ferdinand, ruler of Inner Austria; and his nephew Philip III, king of Spain. All three, however, turned him down.
Albert had in 1609 succeeded in bringing the war between Spain and the Dutch Republic to a temporary close with the Twelve Years' Truce. The last thing he wanted was to involve his ravaged country in supplying men and money to Vienna, perhaps provoking countermeasures from Protestants nearer home. Archduke Ferdinand, although willing to aid Matthias to uphold his authority (not least because he regarded himself as heir presumptive to the childless Matthias), was prevented from doing so by the outbreak of war between his Croatian subjects and the neighbouring republic of Venice (the Uskok War, 1615–18). Philip of Spain was also involved in war: in 1613–15 and 1616–17, Spanish forces in Lombardy fought the troops of the duke of Savoy over the succession to the childless duke of Mantua. Spain could therefore aid neither Matthias nor Ferdinand.
In 1617, however, papal diplomats secured a temporary settlement of the Mantuan question, and Spanish troops hastened to the aid of Ferdinand. Before long, Venice made overtures for peace, and the archduke was able to leave his capital at Graz in order to join Matthias. The emperor, old and infirm, was anxious to establish Ferdinand as his heir, and, in the autumn of 1617, the Estates of both Bohemia and Hungary were persuaded to recognize the archduke unconditionally as king-designate. On the strength of this, Ferdinand proceeded over the winter of 1617–18 to halt the concessions being made to Protestants. He created a council of regency for Bohemia that was overwhelmingly Catholic, and it soon began to censor works printed in Prague and to prevent non-Catholics from holding government office. More inflammatory still, the regents ordered Protestant worship to stop in towns on church lands (which they claimed were not included in the Letter of Majesty).
The Defensors created by the Letter of Majesty expressed strong objection to these measures and summoned the Estates of the realm to meet in May 1618. When the regents declared the meeting illegal, the Estates invaded the council chamber and threw two Catholic regents, together with their secretary, from the window. Next, a provisional government (known as the Directors) was created and a small army was raised.
Apart from the famous “defenestration,” the events in Prague in May 1618 were, superficially, little different from those in 1609 and 1611. Yet no 30-year struggle arose from those earlier crises. The crucial difference lay in the involvement of foreign powers: in 1609 and 1611 the Habsburgs, represented by Rudolf and Matthias, had given in to their subjects' demands; in 1618, led by Ferdinand, they did not. At first his defiant stance achieved nothing, for the army of the rebels expelled loyal troops from almost every part of the kingdom while their diplomats secured declarations of support from Silesia, Lusatia, and Upper Austria almost at once and from Moravia and Lower Austria shortly afterward. In May 1619 the rebel army even laid siege to Ferdinand in Vienna. Within weeks, however, they were forced to withdraw because a major Spanish army, partly financed by the pope, invaded Bohemia.
The appearance of Spanish troops and papal gold in eastern Europe immediately reawakened the fears of the Protestant rulers of the empire. To the government of Philip III, led by the former ambassador in Vienna, Don Balthasar de Zúñiga, the choice had seemed clear: “Your Majesty should consider,” wrote one minister, “which will be of the greater service to you: the loss of these provinces [to the house of Habsburg], or the dispatch of an army of 15 to 20 thousand men to settle the matter.” Seen in these terms, Spain could scarcely avoid military intervention in favour of Ferdinand; but to Protestant observers the logic of Spanish intervention seemed aggressive rather than defensive. Dudley Carleton, the English ambassador to the Dutch Republic, observed that the new emperor “flatters himself with prophesies of extirpating the Reformed religion and restoring the Roman church to the ancient greatness” and accurately predicted that, if the Protestant cause were to be “neglected and by consequence suppressed, the Protestant princes adjoining [Bohemia] are like to bear the burden of a victorious army.”
This same argument carried weight with the director of the Protestant Union, Frederick V of the Palatinate, parts of whose territories adjoined Bohemia. So, when in the summer of 1619 the Bohemians deposed Ferdinand and offered the crown to Frederick, he was favourably disposed. Some of the elector's advisers favoured rejecting this offer, since “acceptance would surely begin a general religious war”; but others pointed out that such a war was inevitable anyway when the Twelve Years' Truce between Spain and the Dutch Republic expired in April 1621 and argued that allowing the Bohemian cause to fail would merely ensure that the conflict in the Netherlands would be resolved in Spain's favour later, making a concerted Habsburg attack on the Protestants of the empire both ineluctable and irresistible.
Frederick accepted the Bohemian crown and in so doing rekindled the worst fears of the German Catholics. The Catholic League was re-created, and in December 1619 its leaders authorized the levy of an army of 25,000 men to be used as Maximilian of Bavaria thought fit. At the same time, Philip III and Archduke Albert each promised to send a new army into Germany to assist Ferdinand (who had succeeded the late Matthias as Holy Roman emperor). The crisis was now apparent, and, as the Palatine diplomat Count John Albert Solms warned his master,
If it is true that the Bohemians are about to depose Ferdinand and elect another king, let everyone prepare at once for a war lasting twenty, thirty or forty years. The Spaniards and the House of Austria will deploy all their worldly goods to recover Bohemia.
The underlying cause for the outbreak of a war that would last 30 years was thus the pathological fear of a Catholic conspiracy among the Protestants and the equally entrenched suspicion of a Protestant conspiracy among the Catholics. As a Bohemian noblewoman, Polyxena Lobkovic, perceptively observed from the vantage point of Prague: “Things are now swiftly coming to the pass where either the papists will settle their score with the Protestants, or the Protestants with the papists.”
The triumph of the Catholics, 1619–29
Frederick V entered Prague and was crowned king by the rebel Estates in October 1619, but already the Catholic net was closing around him. The axis linking Vienna with Munich, Brussels, and Madrid enjoyed widespread support: subsidies came from Rome and Genoa, while Tuscany and Poland sent troops. Equally serious, states favourable to Frederick's cause were persuaded to remain neutral: Spanish diplomacy kept England out of the war, while French efforts persuaded the Protestant Union to remain aloof from the Bohemian adventure of their leader. The Dutch Republic also did nothing, so that in the summer of 1620 a Spanish army was able to cross from the Netherlands and occupy the Rhine Palatinate. Meanwhile, the armies of the emperor and League, reinforced with Spanish and Italian contingents, invaded the rebel heartland. On November 8, in the first significant battle of the war, at the White Mountain outside Prague, Frederick's forces were routed. The unfortunate prince fled northward, abandoning his subjects to the mercy of the victorious Ferdinand.
This was total victory, and it might have remained the last word but for events in the Low Countries. Once the Twelve Years' Truce expired in April 1621, the Dutch, fearing a concerted attack by both Spanish and Austrian Habsburgs, decided to provide an asylum for the defeated Frederick and to supply diplomatic and, eventually, military assistance to his cause. In 1622 and again in 1623, armies were raised for Frederick with Dutch money, but they were defeated. Worse, the shattered armies retreated toward the Netherlands, drawing the Catholic forces behind them. It began to seem that a joint Habsburg invasion of the republic was inevitable after all.
The emperor's political position, however, weakened considerably in the course of 1623. Although his armies won impressive victories in the field, they were only able to do so thanks to massive financial and military support from the Catholic League, controlled by Maximilian of Bavaria. Ferdinand II, thanks to the Spanish and papal subsidies, maintained some 15,000 men himself, but the League provided him with perhaps 50,000. Thus Maximilian's armies had, in effect, won Ferdinand's victories and, now that all common enemies had been defeated, Maximilian requested his reward: the lands and electoral title of the outlawed Frederick of the Palatinate. Don Balthasar de Zúñiga, chief minister of Ferdinand's other major ally, Spain, warned that the consequences of acceding to this demand could be serious, but in October 1622 he died, and no one else in Madrid—least of all his successor as principal minister, the Count-Duke of Olivares—had practical experience of German affairs; so in January 1623 the emperor felt able to proceed with the investiture of Maximilian as elector Palatine.
Zúñiga, however, had been right: the electoral transfer provoked an enormous outcry, for it was clearly unconstitutional. The Golden Bull of 1356, which was universally regarded in Germany as the fundamental and immutable law of the empire, ordained that the electorate should remain in the Palatine house in perpetuity. The transfer of 1623 thus undermined a cornerstone of the Constitution, which many regarded as their only true safeguard against absolute rule. Inside Germany, a pamphlet war against Maximilian and Ferdinand began; outside, sympathy for Frederick at last created that international body of support for his cause which had previously been so conspicuously lacking. The Dutch and the Palatine exiles found little difficulty in engineering an alliance involving France, England, Savoy, Sweden, and Denmark that was dedicated to the restoration of Frederick to his forfeited lands and titles (the Hague Alliance, Dec. 9, 1624). Its leader was Christian IV of Denmark (1588–1648), one of the richest rulers in Christendom, who saw a chance to extend his influence in northern Germany under cover of defending “the Protestant cause.” He invaded the empire in June 1625.
The Protestants' diplomatic campaign had not gone unnoticed, however. Maximilian's field commander, Count Tilly, warned that his forces alone would be no match for a coalition army and asked that the emperor send reinforcements. Ferdinand obliged: in the spring of 1625 he authorized Albrecht von Wallenstein, military governor of Prague, to raise an imperial army of 25,000 men and to move it northward to meet the Danish threat. Wallenstein's approach forced Christian to withdraw; when the Danes invaded again the following year, they were routed at the Battle of Lutter (Aug. 26, 1626). The joint armies of Tilly and Wallenstein pursued the defeated forces: first they occupied the lands of North German rulers who had declared support for the invasion, then they conquered the Danish mainland itself. Christian made peace in 1629, promising never again to intervene in the empire. His allies had long since withdrawn from the struggle.
The White Mountain delivered the Bohemian rebels into the emperor's grasp; Lutter delivered the rebels' German supporters. After the victories, important new policies were initiated by Ferdinand which aimed at exalting the Catholic religion and his own authority. In the Habsburg provinces there was widespread confiscation of land—perhaps two-thirds of the kingdom of Bohemia changed hands during the 1620s—and a new class of loyal landowners—like Wallenstein—was established. At the same time, the power of the Estates was curtailed and freedom of worship for Protestants was restricted (in some territories) or abolished (in most of the rest). Even a rebellion in Upper Austria in 1626, provoked principally by the persecution of Protestants, failed to change Ferdinand's mind. Indeed, fortified by his success in the Habsburg lands, he decided to implement new policies in the empire. First, disloyal rulers were replaced (the Palatinate went to Maximilian, Mecklenburg to Wallenstein, and so on). Next, serious steps were taken to reclaim church lands that had fallen into Protestant hands. At first this was done on a piecemeal basis, but on March 28, 1629, an Edict of Restitution was issued which declared unilaterally that all church lands secularized since 1552 must be returned at once, that Calvinism was an illegal creed in the empire, and that ecclesiastical princes had the same right as secular ones to insist that their subjects should be of the same religion as their ruler. The last clause, at least, was clearly contrary to the terms of the Peace of Augsburg, which Protestants regarded as a central pillar of the Constitution. There was, however, no opportunity for argument, for the imperial edict was enforced immediately, brutally, by the armies of Wallenstein and Tilly, which now numbered some 200,000 men. The people of the empire seemed threatened with an arbitrary rule against which they had no defense. It was this fear, skillfully exploited once again by Protestant propagandists, which ensured that the war in Germany did not end in 1629 with the defeat of Denmark. Ferdinand may have won numerous military victories, but in doing so he had suffered a serious political defeat. The pens of his enemies proved mightier than the sword.
The crisis of the war, 1629–35
If Maximilian of Bavaria desired the title of elector as his reward for supporting Ferdinand, Spain (for its part) required imperial support for its war against the Dutch. When repeated requests for a direct invasion by Wallenstein's army remained unanswered (largely due to Bavarian opposition), Spain began to think of creating a Baltic navy, with imperial assistance, which would cleanse the inland sea of Dutch shipping and thus administer a body blow to the republic's economy. But the plan aborted, for the imperial army failed in 1628 to conquer the port of Stralsund, selected as the base for the new fleet. Now, with Denmark defeated, Madrid again pleaded for the loan of an imperial army, and this time the request was granted. In the end, however, the troops did not march to the Netherlands: instead, they went to Italy.
The death of the last native ruler of the strategic states of Mantua and Montferrat in December 1627 created dangers in Italy that the Spaniards were unable to ignore and temptations that they were unable to resist. Hoping to forestall intervention by others, Spanish forces from Lombardy launched an invasion, but the garrisons of Mantua and Montferrat declared for the late duke's relative, the French-born duke of Nevers. Nevers lacked the resources to withstand the forces of Spain alone, and he appealed to France for support. Louis XIII (1610–43) and Cardinal Richelieu (chief minister 1624–42) were, however, engaged in a desperate war against their Calvinist subjects; only when the rebels had been defeated, early in 1629, was it possible for the king and his chief minister to cross the Mount Cenis Pass and enter Italy. It was to meet this threat that the emperor was asked by Philip IV of Spain (1621–65) to send his troops to Italy rather than to the Netherlands. When Louis XIII launched a second invasion in 1630, some 50,000 imperial troops were brought south to oppose them, reducing the war for Mantua to a stalemate but delivering the Dutch Republic from immediate danger and weakening the emperor's hold on Germany.
Gustav II Adolf of Sweden (1611–32) had spent most of the 1620s at war with Poland, seeking to acquire territory on the southern shore of the Baltic. By the Truce of Altmark (Sept. 26, 1629), with the aid of French and British mediators, Poland made numerous concessions in return for a six-year truce. Gustav lost no time in redeploying his forces: on July 6, 1630, he led a Swedish expeditionary force ashore near Stralsund with the declared intention of saving the “liberties of the empire” and preserving the security of the Baltic.
Despite the defeat of the German Protestants and their allies, Sweden's position was far more favourable than that of Denmark five years earlier. Instead of the two armies that had faced Christian IV, Gustav was opposed by only one, for in the summer of 1630 the emperor's Catholic allies in Germany—led by Maximilian of Bavaria—demanded the dismissal of Wallenstein and the drastic reduction of his expensive army. It was an ultimatum that Ferdinand, with the bulk of his forces tied down in the war of Mantua, could not ignore, even though he thereby lost the services of the one man who might conceivably have retained all the imperial gains of the previous decade and united Germany under a strong monarchy.
The emperor and his German allies, nevertheless, did remain united over the Edict of Restitution: there were to be no concessions in matters of religion and no restoration of forfeited lands. As a result, the German Protestants were driven reluctantly into the arms of Sweden, whose army was increased with the aid of subsidies secured from France and the Dutch. In September 1631 Gustav at last felt strong enough to challenge the emperor's forces in battle: at Breitenfeld, just outside Leipzig in Saxony, he was totally victorious. The main Catholic field army was destroyed, and the Swedish Protestant host overran most of central Germany and Bohemia in the winter of 1631–32. The next summer they occupied Bavaria. Although Gustav died in battle at Lützen on Nov. 16, 1632, his forces were again victorious and his cause was directed with equal skill by his chief adviser, Axel Oxenstierna. In the east, Sweden managed to engineer a Russian invasion of Poland in the autumn of 1632 that tied down the forces of both powers for almost two years. Meanwhile, in Germany, Oxenstierna crafted a military alliance that transferred much of the cost of the war onto the shoulders of the German Protestant states (the Heilbronn League, April 23, 1633). Swedish ascendancy, however, was destroyed in 1634 when Russia made peace with Poland (at Polyanov, June 4) and Spain sent a large army across the Alps from Lombardy to join the imperial forces at the Battle of Nördlingen (September 6). This time the Swedes were decisively beaten and were obliged to withdraw their forces in haste from most of southern Germany.
Yet Sweden, under Oxenstierna's skillful direction, fought on. Certainly its motives included a desire to defend the Protestant cause in Germany and to restore deposed princes to their thrones; but more important by far was the fear that, if the German Protestants were finally defeated, the imperialists would turn the Baltic into a Habsburg lake and might perhaps invade Sweden. The Stockholm government therefore desired a settlement that would atomize the empire into a jumble of independent, weak states incapable of threatening the security of Sweden or its hold on the Baltic. Furthermore, to guarantee this fragmentation, Oxenstierna desired the transfer to his country of sovereignty over certain strategic areas of the empire—particularly the duchy of Pomerania on the Baltic coast and the electorate of Mainz on the Rhine.
These, however, were not at all the goals of Sweden's German allies. They aimed rather at the restoration of the prewar situation—in which there had been no place for Sweden—and it soon became clear that they were prepared to make a separate settlement with the emperor in order to achieve it. No sooner was Gustav dead than the elector of Saxony, as “foremost Lutheran prince of the Empire,” put out peace-feelers toward Vienna. At first John George (1611–56) was adamant about the need to abolish the Edict of Restitution and to secure a full amnesty for all as preconditions for a settlement; but the imperial victory at Nördlingen made him less demanding. The insistence on an amnesty for Frederick V was dropped, and it was accepted that the edict would be applied in all areas recovered by Catholic forces before November 1627 (roughly speaking, this affected all lands south of the Elbe, but not the Lutheran heartland of Saxony and Brandenburg). The elector might have been required to make even more concessions but for the fact that, over the winter of 1634–35, French troops began to mass along the borders of Germany. As the papal nuncio in Vienna observed: “If the French intervene in Germany, the emperor will be forced to conclude peace with Saxony on whatever terms he can.” So the Peace of Prague was signed between the emperor and the Saxons on May 30, 1635, and within a year most other German Lutherans also changed their allegiance from Stockholm to Vienna.
The European war in Germany 1635–45
This partial settlement of the issues behind the war led many in Germany to look forward to a general peace. Certainly the exhaustion of many areas of the empire was a powerful incentive to end the war. The population of Lutheran Württemberg, for example, which was occupied by the imperialists between 1634 and 1638, fell from 450,000 to 100,000; material damage was estimated at 34 million thalers. Mecklenburg and Pomerania, occupied by the Swedes, had suffered in proportion. Even a city like Dresden, the capital of Saxony, which was neither besieged nor occupied, saw its demographic balance change from 121 baptisms for every 100 burials in the 1620s to 39 baptisms for every 100 burials in the 1630s. Amid such catastrophes an overwhelming sense of war-weariness engulfed Germany. The English physician William Harvey (discoverer of the circulation of blood), while visiting Germany in 1636, wrote:
The necessity they have here is of making peace on any condition, where there is no more means of making war and scarce of subsistence. . . . This warfare in Germany . . . threatens, in the end, anarchy and confusion.
Attempts were made to convert the Peace of Prague into a general settlement. At a meeting of the electors held at Regensburg in 1636–37, Ferdinand II agreed to pardon any prince who submitted to him and promised to begin talks with the foreign powers to discover their terms for peace. But the emperor's death immediately after the meeting ended this initiative. Efforts by Pope Urban VIII (1623–44) to convene a general conference at Cologne were similarly unavailing. Then, in 1640, the new emperor, Ferdinand III (1637–57), assembled the Imperial Diet for the first time since 1613 in order to solve at least the outstanding German problems of the amnesty question and the restitution of church lands. He met with little success and could not prevent first Brandenburg (1641) and then Brunswick (1642) from making a separate agreement with Sweden. The problem was that none of these attempts at peace were acceptable to France and Sweden, yet no lasting settlement could be made without them.
After the Peace of Prague, the nature of the Thirty Years' War was transformed. Instead of being principally a struggle between the emperor and his own subjects, with some foreign aid, it became a war of the emperor against foreign powers whose German supporters were, at most times, few in number and limited in resources. Sweden, as noted above, had distinct and fairly consistent war aims: to secure some bases in the empire, both as guarantees of influence in the postwar era and as some recompense for coming to the rescue of the Protestants, and to create a system of checks and balances in Germany, which would mean that no single power would ever again become dominant. If those aims could be achieved, Oxenstierna was prepared to quit. As he wrote:
We must let this German business be left to the Germans, who will be the only people to get any good out of it (if there is any), and therefore not spend any more men or money, but rather try by all means to wriggle out of it.
But how could these objectives be best achieved? The Heilbronn League did not long survive the Battle of Nördlingen and the Peace of Prague, and so it became necessary to find an alternative source of support. The only one available was France. Louis XIII and Richelieu, fresh from their triumph in Italy, had been subsidizing Sweden's war effort for some time. In 1635, in the wake of Nördlingen, they signed an offensive and defensive alliance with the Dutch Republic (February 8), with Sweden (April 28), and with Savoy (July 11); they sent an army into the Alps to occupy the Valtelline, a strategic military link between the possessions of the Spanish and Austrian Habsburgs (March); and they mediated a 20-year truce between Sweden and Poland (September 12). Finally, on May 19, 1635, they declared war on Spain.
The aims of France were very different from those of Sweden and its German allies. France wished to defeat Spain, its rival for more than a century, and its early campaigns in Germany were intended more to prevent Ferdinand from sending aid to his Spanish cousins than to impose a Bourbon solution on Germany—indeed, France only declared war on Ferdinand in March 1636. Sweden at first therefore avoided a firm commitment to France, leaving the way clear for a separate peace should the military situation improve sufficiently to permit the achievement of its own particular aims. The war, however, did not go in favour of the allies. French and Swedish forces, operating separately, totally failed to reverse the verdict of Nördlingen: despite the Swedish victory at Wittstock (Oct. 4, 1636) and French gains in Alsace and the middle Rhine (1638), the Habsburgs always seemed able to even up the score. Thus in 1641 Oxenstierna abandoned his attempt to maintain independence and threw in his lot with France. By the terms of the Treaty of Hamburg (March 15, 1641), the two sides promised not to make a separate peace. Instead, joint negotiations with the emperor and the German princes for the satisfaction of the allies' claims were to begin in the Westphalian towns of Münster and Osnabrück. And, while the talks proceeded, the war was to continue.
The Treaty of Hamburg had at last created a coalition capable of destroying the power both of Ferdinand III and of Maximilian of Bavaria. On the whole, France attacked Bavaria, and Sweden fought the emperor; but there was considerable interchange of forces and a carefully coordinated strategy. On Nov. 2, 1642, the Habsburgs' army was routed in Saxony at the Second Battle of Breitenfeld, and the emperor was saved from further defeat only by the outbreak of war between Denmark and Sweden (May 1643–August 1645). Yet, even before Denmark's final surrender, the Swedes were back in Bohemia, and at Jankov (March 6, 1645) they totally destroyed another imperial army. The emperor and his family fled to Graz, while the Swedes advanced to the Danube and threatened Vienna. Reinforcements were also sent to assist the French campaign against Bavaria, and on August 3 Maximilian's forces were decisively defeated at Allerheim.
Jankov and Allerheim were two of the truly decisive battles of the war, because they destroyed all possibility of the Catholics obtaining a favourable peace settlement. In September 1645 the elector of Saxony made a separate peace with Sweden and so—like Brandenburg and Brunswick before him—in effect withdrew from the war. Meanwhile, at the peace conference in session in Westphalia, the imperial delegation began to make major concessions: Oxenstierna noted with satisfaction that, since Jankov, “the enemy begins to talk more politely and pleasantly.” He was confident that peace was just around the corner. He was wrong.
Making peace, 1645–48
One hundred and ninety-four European rulers, great and small, were represented at the Congress of Westphalia, and talks went on constantly from the spring of 1643 until the autumn of l648. The outstanding issues of the war were solved in two phases: the first, which lasted from November 1645 until June 1647, saw the chief imperial negotiator, Maximilian, Count Trauttmannsdorf, settle most issues; the second, which continued from then until the treaty of peace was signed in October 1648, saw France try to sabotage the agreements already made.
The purely German problems were resolved first, partly because they were already near solution and partly because the foreign diplomats realized that it was best (in the words of Count d'Avaux, the French envoy)
to place first on the table the items concerning public peace and the liberties of the Empire, . . . because if the German rulers do not yet truly wish for peace, it would be . . . damaging to us if the talks broke down over our own particular demands.
So in 1645 and 1646, with the aid of French and Swedish mediation, the territorial rulers were granted a large degree of sovereignty (Landeshoheit), a general amnesty was issued to all German princes, an eighth electorate was created for the son of Frederick V (so that both he and Maximilian possessed the coveted dignity), the Edict of Restitution was finally abandoned, and Calvinism within the empire was granted official toleration. The last two points were the most bitterly argued and led to the division of the German rulers at the Congress into two blocs: the Corpus Catholicorum and the Corpus Evangelicorum. Neither was monolithic or wholly united, but eventually the Catholics split into those who were prepared to make religious concessions in order to have peace and those who were not. A coalition of Protestants and pragmatic Catholics then succeeded in securing the acceptance of a formula that recognized as Protestant all church lands in secular hands by Jan. 1, 1624 (that is, before the gains made by Wallenstein and Tilly), and granted freedom of worship to religious minorities where these had existed by the same date. The Augsburg settlement of 1555 was thus entirely overthrown, and it was agreed that any change to the new formula must be achieved only through the “amicable composition” of the Catholic and Protestant blocs, not by a simple majority.
The amicable composition principle was finally accepted by all parties early in l648, thus solving the last German problem. That this did not lead to immediate peace was due to the difficulty of satisfying the foreign powers involved. Apart from France and Sweden, representatives from the Dutch Republic, Spain, and many other non-German participants in the war were present, each of them eager to secure the best settlement they could. The war in the Netherlands was the first to be ended: on Jan. 30, 1648, Philip IV of Spain signed a peace that recognized the Dutch Republic as independent and agreed to liberalize trade between the Netherlands and the Iberian world. The French government, led since Richelieu's death (Dec. 4, 1642) by Jules Cardinal Mazarin (Giulio Mazzarino), was bitterly opposed to this settlement, since it left Spain free to deploy all its forces in the Low Countries against France; as a consequence, France devoted all its efforts to perpetuating the war in Germany. Although Mazarin had already signed a preliminary agreement with the emperor in September 1646, which conveyed parts of Alsace and Lorraine to France, in 1647–48 he started a new campaign in Germany in order to secure more. On May 17, l648, another Bavarian army was destroyed at Zusmarshausen, near Nördlingen, and Maximilian's lands were occupied by the French.
Mazarin's desire to keep on fighting was thwarted by two developments. On the one hand, the pressure of the war on French taxpayers created tensions that in June l648 erupted into the revolt known as the Fronde. On the other hand, Sweden made a separate peace with the emperor. The Stockholm government, still directed by Oxenstierna, was offered half of Pomerania, most of Mecklenburg, and the secularized bishoprics of Bremen and Verden; it was to receive a seat in the Imperial Diet; and the territories of the empire promised to pay five million thalers to the Swedish army for its wage arrears. With so many tangible gains, and with Germany so prostrated that there was no risk of any further imperial attack, it was clearly time to wriggle out of the war, even without France; peace was thus signed on August 6.
Without Sweden, Mazarin realized that France needed to make peace at the earliest opportunity. He informed his representatives at the Congress:
It is almost a miracle that . . . we can keep our affairs going, and even make them prosper; but prudence dictates that we should not place all our trust in this miracle continuing for long.
Mazarin therefore settled with the emperor on easy terms: France gained only the transfer of a bundle of rights and territories in Alsace and Lorraine and little else. Mazarin could, nevertheless, derive satisfaction from the fact that, when the ink dried on the final treaty of Oct. 24, l648, the emperor was firmly excluded from the empire and was under oath to provide no further aid to Spain. Mazarin settled down to suppress the Fronde revolt and to win the war against Philip IV.
Problems not solved by the war
Some historians have sought to diminish the achievements of the Thirty Years' War, and the peace that ended it, because not all of Europe's outstanding problems were settled. The British historian C.V. Wedgwood, for example, in a classic study of the war first published in 1938, stated baldly:
The war solved no problem. Its effects, both immediate and indirect, were either negative or disastrous. . . . It is the outstanding example in European history of meaningless conflict
It is true that the struggle between France and Spain continued with unabated bitterness until 1659 and that, within a decade of the Westphalian settlement, Sweden was at war with Poland (1655–60), Russia (1656–58), and Denmark (1657–58). It is also true that, in the east, a war broke out in 1654 between Poland and Russia that was to last until 1667, while tension between the Habsburgs and the Turks increased until war came in 1663. Even within the empire, there were disputes over the partition of Cleves-Jülich, still a battle zone after almost a half-century, which caused minor hostilities in 1651. Lorraine remained a theatre of war until the duke signed a final peace with France in 1661. But to expect a single conflict in early modern times to have solved all of Europe's problems is anachronistic: the continent was not the single political system that it later became. It is wrong to judge the Congress of Westphalia by the standard of the Congress of Vienna (1815). Examined more closely, the peace conference that ended the Thirty Years' War settled a remarkable number of crucial issues.
Problems solved by the war
The principal Swedish diplomat at Westphalia, Johann Adler Salvius, complained to his government in 1646 that
people are beginning to see the power of Sweden as dangerous to the balance of power. Their first rule of politics here is that the security of all depends upon the equilibrium of the individuals. When one ruler begins to become powerful . . . the others place themselves, through unions or alliances, into the opposite balance in order to maintain the equipoise.
It was the beginning of a new order in Europe, and Sweden, for all her military power, was forced to respect it. The system depended on channeling the aggression of German princes from thoughts of conquering their neighbours to dreams of weakening them; and it proved so successful that, for more than a century, the settlement of l648 was widely regarded as the principal guarantee of order and peace in central Europe. In 1761 Jean-Jacques Rousseau wrote in praise of the “balance of power” in Europe which, he believed, was anchored in the constitution of the Holy Roman Empire
which takes from conquerors the means and the will to conquer. . . . Despite its imperfections, this Imperial constitution will certainly, while it lasts, maintain the balance in Europe. No prince need fear lest another dethrone him. The peace of Westphalia may well remain the foundation of our political system for ever.
As late as 1866, the French statesman Adolphe Thiers claimed that
Germany should continue to be composed of independent states connected only by a slender federative thread. That was the principle proclaimed by all Europe at the Congress of Westphalia.
It was indeed: the balance of power with its fulcrum in Germany, created by the Thirty Years' War and prolonged by the Peace of Westphalia, was a major achievement. It may not have lasted, as Rousseau rashly prophesied, forever, but it certainly endured for more than a century.
It was, for example, almost a century before German rulers went to war with each other again—a strong contrast with the hundred years before 1618, which had been full of armed neutrality and actual conflict. The reason for the contrast was simple: the Thirty Years' War had settled both of the crises which had so disturbed the peace in the decades before it began.
In the lands of the Austrian Habsburgs, there were now no powerful estates and no Protestant worship (except in Hungary), and, despite all the efforts of the Swedish diplomats at Westphalia, there was no restoration of the lands confiscated from rebels and others. The Habsburg Monarchy, born of disparate units but now entirely under the authority of the king-emperor, had become a powerful state in its own right. Purged of political and religious dissidents and cut off from its western neighbours and from Spain, the compact private territories of the Holy Roman emperor were still large enough to guarantee him a place among the foremost rulers of Europe. In the empire, by contrast, the new stability rested upon division rather than unity. Although the territorial rulers had acquired, at Westphalia, supreme power in their localities and collective power in the Diet to regulate common taxation, defense, laws, and public affairs without imperial intervention, the “amicable composition” formula prevented in fact any changes being made to the status quo. The originality of this compromise (enshrined in Article V, paragraph 52, of the Instrumentum Pacis Osnabrugense) has not always been appreciated. An age that normally revered the majority principle sanctioned an alternative method—parity between two unequal groups (known as itio in partes)—for reaching decisions.
Looked at more pragmatically, what the itio in partes formula achieved was to remove religion as a likely precipitant of political conflict. Although religion remained a matter of high political importance (for instance, in cementing an alliance against Louis XIV after 1685 or in unseating James II of England in 1688), it no longer determined international relations as it once had done.
When one of the diplomats at the Congress of Westphalia observed that “reason of state is a wonderful animal, for it chases away all other reasons,” he in fact paid tribute to the secularization that had taken place in European politics since 1618. But when, precisely, did it happen? Perhaps with the growing preponderance of non-German rulers among the enemies of the emperor. Without question, those German princes who took up arms against Ferdinand II were strongly influenced by confessional considerations, and, as long as these men dominated the anti-Habsburg cause, so too did the issue of religion. Frederick of the Palatine and Christian of Anhalt, however, failed to secure a lasting settlement. Gradually the task of defending the Protestant cause fell into the hands of Lutherans, less militant and less intransigent than the Calvinists; and the Lutherans were prepared to ally, if necessary, with Anglican England, Catholic France, and even Orthodox Russia in order to create a coalition capable of defeating the Habsburgs. Naturally such states had their own reasons for fighting; and, although upholding the Protestant cause may have been among them, it seldom predominated. After 1625, therefore, the role of religious issues in European politics steadily receded. This was, perhaps, the greatest achievement of the war, for it thus eliminated the major destabilizing influence in European politics, which had both undermined the internal cohesion of many states and overturned the diplomatic balance of power created during the Renaissance.
