were steadily reconquering. In 1604, with both Philip II and Elizabeth dead, Spain and England came to a compromise peace. It would take another five years, until the truce of 1609, before Madrid negotiated with the Dutch rebels for peace; but well before then it had become clear that Spanish power was insufficient to crush the Netherlands, either by sea or through the strongly held land (and watery) defences manned by Maurice of Nassau’s efficient Dutch army. The continued existence of all three states, France, England, and the United Provinces of the Netherlands, each with the potential to dispute Habsburg pretensions in the future, again confirmed that the Europe of 1600 would consist of many nations, and not of one hegemony.
The third great spasm of wars which convulsed Europe in this period occurred after 1618, and fell very heavily upon Germany. That land had been spared an all-out confessional struggle in the late sixteenth century, but only because of the weakening authority and intellect of Rudolf II (Holy Roman emperor, 1576–1612) and a renewal of a Turkish threat in the Danube basin (1593–1606). Behind the facade of German unity, however, the rival Catholic and Protestant forces were manoeuvring to strengthen their own position and to weaken that of their foes. As the seventeenth century unfolded, the rivalry between the Evangelical Union (founded in 1608) and the Catholic League (1609) intensified. Moreover, because the Spanish Habsburgs strongly supported their Austrian cousins, and because the head of the Evangelical Union, the Elector Palatine Frederick IV, had ties with both England and the Netherlands, it appeared as if most of the states of Europe were lining up for a final settlement of their political-religious antagonisms.11
The 1618 revolt of the Protestant estates of Bohemia against their new Catholic ruler, Ferdinand II (emperor 1619–37), therefore provided the spark needed to begin another round of ferocious religious struggles: the Thirty Years War of 1618–48. In the early stages of this contest, the emperor’s forces fared well, ably assisted by a Spanish-Habsburg army under General Spinola. But, in consequence, a heterogeneous combination of religious and worldly forces entered the conflict, once again eager to adjust the balances in the opposite direction. The Dutch, who ended their 1609 truce with Spain in 1621, moved into the Rhineland to counter Spinola’s army. In 1626, a Danish force under its monarch Christian IV invaded Germany from the north. Behind the scenes, the influential French statesman Cardinal Richelieu sought to stir up trouble for the Habsburgs wherever he could. However, none of these military or diplomatic countermoves were very successful, and by the late 1620s the Emperor Ferdinand’s powerful lieutenant, Wallenstein, seemed well on the way to imposing an all-embracing, centralized authority on Germany, even as far north as the Baltic shores.12
Yet this rapid accumulation of imperial power merely provoked the House of Habsburg’s many enemies to strive the harder. In the early 1630s by far the most decisive of them was the attractive and influential Swedish king, Gustavus Adolphus II (1611–32), whose well-trained army moved into northern Germany in 1630 and then burst southward to the Rhineland and Bavaria in the following year. Although Gustavus himself was killed at the battle of Lützen in 1632, this in no way diminished the considerable Swedish role in Germany – or, indeed, the overall dimensions of the war. On the contrary, by 1634 the Spaniards under Philip IV (1621–65) and his accomplished first minister, the Count-Duke of Olivares, had decided to aid their Austrian cousins much more thoroughly than before; but their dispatch into the Rhineland of a powerful Spanish army under its general, the Cardenal-Infante, in turn forced Richelieu to decide upon direct French involvement, ordering troops across various frontiers in 1635. For years beforehand, France had been the tacit, indirect leader of the anti-Habsburg coalition, sending subsidies to all who would fight the imperial and Spanish forces. Now the conflict was out in the open, and each coalition began to mobilize even more troops, arms, and money. The language correspondingly became stiffer. ‘Either all is lost, or else Castile will be head of the world’, wrote Olivares in 1635, as he planned the triple invasion of France in the following year.13
The conquest of an area as large as France was, however, beyond the military capacities of the Habsburg forces, which briefly approached Paris but were soon hard stretched across Europe. Swedish and German troops were pressing the imperial armies in the north. The Dutch and the French were ‘pincering’ the Spanish Netherlands. Moreover, a revolt by the Portuguese in 1640 diverted a steady flow of Spanish troops and resources from northern Europe to much nearer home, although they were never enough to achieve the reunification of the peninsula. Indeed, with the parallel rebellion of the Catalans – which the French gladly aided – there was some danger of a disintegration of the Spanish heartland by the early 1640s. Overseas, Dutch maritime expeditions struck at Brazil, Angola, and Ceylon, turning the conflict into what some historians describe as the first global war.14 If the latter actions brought gains to the Netherlands, most of the other belligerents were by this time suffering heavily from the long years of military effort; the armies of the 1640s were becoming smaller than those of the 1630s, the financial expedients of governments were the more desperate, the patience of the people was much thinner and their protests much more violent. Yet precisely because of the interlinked nature of the struggle, it was difficult for any one participant to withdraw. Many of the Protestant German states would have done just that, had they been certain that the Swedish armies would also cease fighting and go home; and Olivares and other Spanish statesmen would have negotiated a truce with France, but the latter would not desert the Dutch. Secret peace negotiations at various levels were carried out in parallel with military campaigns on various fronts, and each power consoled itself with the thought that another victory would buttress its claims in the general settlement.
The end of the Thirty Years War was, in consequence, an untidy affair. Spain suddenly made peace with the Dutch early in 1648, finally recognizing their full independence; but this was done to deprive France of an ally, and the Franco-Habsburg struggle continued. It became purely a Franco-Spanish one later in the year when the Peace of Westphalia at last brought tranquillity to Germany, and allowed the Austrian Habsburgs to retire from the conflict. While individual states and rulers made certain gains (and suffered certain losses), the essence of the Westphalian settlement was to acknowledge the religious and political balance within the Holy Roman Empire, and thus to confirm the limitations upon imperial authority. This left France and Spain engaged in a war which was all to do with national rivalries and nothing to do with religion – as Richelieu’s successor, the French minister, Mazarin, clearly demonstrated in 1655 by allying with Cromwell’s Protestant England to deliver the blows which finally caused the Spaniards to agree to a peace. The conditions of the Treaty of the Pyrenees (1659) were not particularly harsh, but in forcing Spain to come to terms with its great archenemy, they revealed that the age of Habsburg predominance in Europe was over. All that was left as a ‘war aim’ for Philip IV’s government then was the preservation of Iberian unity, and even this had to be abandoned in 1668, when Portugal’s independence was formally recognized.15 The continent’s political fragmentation thus remained in much the same state as had existed at Charles V’s accession in 1519, although Spain itself was to suffer from further rebellions and losses of territory as the seventeenth century moved to its close (see Map 4) – paying the price, as it were, for its original strategical overextension.
Strengths and Weaknesses of the Habsburg Bloc
Why did the Habsburgs fail?16 This issue is so large and the process was so lengthy that there seems little point in looking for personal reasons like the madness of the Emperor Rudolf II, or the incompetence of Philip III of Spain. It is also difficult to argue that the Habsburg dynasty and its higher officers were especially deficient when one considers the failings of many a contemporary French and English monarch, and the venality or idiocy of some of the German princes. The puzzle appears the greater when one recalls the vast accumulation of material power available to the Habsburgs:
