"But despite the occasional rhetoric of some Habsburg ministers about a “world monarchy,” there was no conscious plan to dominate Europe in the manner of Napoleon or Hitler. Some of the Habsburg dynastic marriages and successions were fortuitous, at the most inspired, rather than evidence of a long-term scheme of territorial aggrandizement. In certain cases—for example, the frequent French invasions of northern Italy—Habsburg rulers were more provoked than provoking. In the Mediterranean after the 1540s, Spanish and imperial forces were repeatedly placed on the defensive by the operations of a revived Islam. Nevertheless, the fact remains that had the Habsburg rulers achieved all of their limited, regional aims—even their defensive aims—the mastery of Europe would virtually have been theirs. The Ottoman Empire would have been pushed back, along the North African coast and out of eastern Mediterranean waters. Heresy would have been suppressed within Germany. The revolt of the Netherlands would have been crushed. Friendly regimes would have been maintained in France and England. Only Scandinavia, Poland, Muscovy, and the lands still under Ottoman rule would not have been subject to Habsburg power and influence—and the concomitant triumph of the Counter-Reformation. Although Europe even then would not have approached the unity enjoyed by Ming China, the political and religious principles favored by the twin Habsburg centers of Madrid and Vienna would have greatly eroded the pluralism that had so long been the continent’s most important feature."
