LAWS OF NATURE IN CIVILIZATIONS 239 the first of the regular cycles of war-and-peace in this series (currebat A.D. 1568-1672), the number rose again from three to five through the successful self-assertion of a United Northern Netherlands that had broken out of the Spanish Monarchy and a Sweden that had broken out of the Danish Monarchy. During the second of these three regular cycles (currebat A.D. 1672- 1792) the number threatened to fall as sharply as it had risen during the preceding cycle; for Spain, as well as the Netherlands and Sweden, now proved unequal to staying the course, while the sixteenth-century fission of the Hapsburg Power into a Spanish and an Austrian branch came into danger of being neutralized by an eighteenth-century union of the Spanish Monarchy with France to create a Bourbon Power which, in the hands of Louis XIV, would have outclassed all the other Powers of the Western World as decidedly as the undivided Hapsburg Power had out- classed its French rival before the abdication of Charles V. None of these possibilities, however, materialized; for the replacement of a Hapsburg by a Bourbon dynasty at Madrid did not, after aU, 'abolish the Pyrenees* ;x a Bourbon Spain remained at least as separate from a Bourbon France after A.D. 1713 as a Hapsburg Spain had been, since A.D. 1556, from a Hapsburg Austria; and the casualties among the parvenues 'just-great* Powers were made good by replacements. A United Kingdom of England and Scotland took the place of a United Netherlands who had exhausted herself in winning a General War of A,D. 1672-1713 in which she had been the protagonist in the anti-French coalition; Prussia took the place of a Sweden who had exhausted herself in waging the Northern War of A.D. 1700-21; and, though an eighteenth-century Spain who succeeded in retaining her independence did not succeed in becoming a Great Power again, this gap in the ranks of the Great Powers of the Western World was filled by the enlistment of an Orthodox Christian Russia whose decisive victory over Sweden had demonstrated the effectiveness of her reception of the Western Civilization, at any rate on the military plane. During the third cycle (currebat A.D. 1792-1914) a number which had thus remained constant during the seventeenth and eighteenth centuries at the figure of five was raised once more, and this time from five to eight, by the successive additions of a United Italy, a United States oi North America, and a Westernizing Japan. A nineteenth-century Italy attained the stature of a 'just-great' Power that had been attained by a seventeenth-century Holland and Sweden. A twentieth-century Japan won her spurs by defeating Russia, as an eighteenth-century Russia had won hers by defeating Sweden. The United States emerged through a fission of an eighteenth-century British Empire which ultimately had the same effect of making two Great Powers out of one as the fission of the Hapsburg Power after the abdication of Charles V, though the secession of the United States from the British Empire was achieved by the force of arms with which Sweden and the United Netherlands had 1 'II n'y a plus de Pyr&i^es1 was Louis XIV's comment on the accession of his grand- son to the throne of Spain in A.D. 1700 according to Voltaire, Le Sticle de Louis Quatorzet chap. 28.
