The book takes issue with established interpretations, not least those that emphasize technology, and challenges the view that European military and naval forces were dominant throughout the period. European mastery at sea did not always translate into equivalent success on land, says Black, and many non-European military systems--the Ottomans in their expansionist years, Babur and the Mughals in sixteenth-century India, and the Manchu in China in the following century, for example--were formidable in their own right. The author contends that in the nineteenth century, the focal period of Europe's military revolution, the international military balance shifted decisively. Black shows how military developments, combined with political, economic, and ideological shifts, influenced the nature and success of European imperialism. Linking debates on early modern history with those of more recent centuries, he offers a fundamental reexamination of the role of war in the progress of nations.
