The Transformation of Alliance Systems

The pattern of international relations has always been in flux. The further we are removed from a period, the easier it is to discern its most salient features. So the fifteenth century now emerges as the time of the birth of the nation-state which was to become the key factor in international relations. Yet the supra-national church was not successfully challenged until the next century. Today it is clear that the French revolution completed the conversion of dynastic states into national states. In retrospect the 18th and particularly the 19th centuries are seen as the high point of the world expansion of Europe and the extension of its system of international relations. Now we realize that the Japanese victory over Russia in 1904–1905 marked the beginning of the counter-offensive against Europe. But what emerges sharply now was obscured then by a welter of incident.
