place in the preceding hundred years; and, as such, these changes reflected a further stage in the evolution of international politics.
The most significant feature of the Great Power scene after 1660 was the maturing of a genuinely
multipolar
system of European states, each one of which increasingly tended to make decisions about war and peace on the basis of “national interests” rather than for transnational, religious causes. This was not, to be sure, an instant or absolute change: the European states prior to 1660 had certainly maneuvered with their secular interests in mind, and religious prejudice still fueled many international quarrels of the eighteenth century. Nevertheless, the chief characteristic of the 1519–1659 era—that is, an Austro-Spanish axis of Habsburg powers fighting a coalition of Protestant states, plus France—now disappeared, and was replaced by a much looser system of short-term, shifting alliances. Countries which had been foes in one war were often to find themselves partners in the next, which placed an emphasis upon calculated
Realpolitik
rather than deeply held religious conviction in the determination of policy.
The fluctuations in both diplomacy and war that were natural to this volatile, multipolar system were complicated by something which was not new, but was common to all ages: the rise of certain states and the decline of others. During this century and a half of international rivalry between Louis XIV’s assumption of full authority in France in 1660–1661 and Napoleon Bonaparte’s surrender after Waterloo in 1815, certain leading nations of the previous period (the Ottoman Empire, Spain, the Netherlands, Sweden) fell back into the second rank, and Poland was eclipsed altogether. The Austrian Habsburgs, by variousterritorial and structural adjustments in their hereditary lands, managed to remain in the first order; and in the north of Germany, Brandenburg-Prussia pulled itself up to that status from unpromising beginnings. In the west, France after 1660 swiftly expanded its military might to become the most powerful of the European states—to many observers, almost as overwhelming as the Habsburg forces had appeared a half-century earlier. France’s capacity to dominate west-central Europe was held in check only by a combination of maritime and continental neighbors during a series of prolonged wars (1689–1697; 1702–1714; 1739–1748; 1756–1763); but it was then refashioned in the Napoleonic era to produce a long line of Gallic military victories which were brought to an end only by a coalition of four other Great Powers. Even in its defeat in 1815, France remained one of the leading states. Between it in the west and the two Germanic countries of Prussia and the Habsburg Empire in the east, therefore, a crude trilateral equilibrium slowly emerged within the European core as the eighteenth century unfolded.
But the really significant alterations in the Great Power system during that century occurred on the
flanks
of Europe, and even farther afield. Certain of the western European states steadily converted their small, precarious enclaves in the tropics into much more extensive domains, especially in India but also in the East Indies, southern Africa, and as far away as Australia. The most successful of these colonizing nations was Britain, which, domestically “stabilized” after James II was replaced by William and Mary in 1688, steadily fulfilled its Elizabethan potential as the greatest of the European maritime empires. Even its loss of control over the prosperous North American colonies in the 1770s—from which there emerged an independent United States of formidable defensive strength and considerable economic power—only temporarily checked this growth of British global influence. Equally remarkable were the achievements of the Russian state, which expanded eastward and southward, across the steppes of Asia, throughout the eighteenth century. Moreover,
