Yale historian Kennedy surveys the ebb and flow of power among the major states of Europe from the 16th centurywhen Europe's preeminence first took shapethrough and beyond the present erawhen great power status is devolving again upon the extra-European states. Stressing the interrelationships among economic wealth, technological innovation, and the ability of states efficiently to tap their resources for prolonged military preparedness and warmaking, he notes that those states with the relatively greater ability to maintain a balance of military and economic strength assumed the lead. Kennedy never reduces the analysis to crude materialism or empty tautology.
