The Influence of Sea Power upon History, 1660-1783

Published in 1890, this revolutionary work arguing that control of the seas determines national greatness became the most influential book on geopolitics of the twentieth century. Mahan systematically examines how Britain, France, the Netherlands, and Spain rose and fell based on their maritime strength, tracing the critical period from 1660 through the American Revolution. He demonstrates how naval commerce, colony possession, and fleet superiority intertwined to create imperial power, drawing lessons from conflicts like the Anglo-Dutch Wars and the War of Spanish Succession. Theodore Roosevelt credited it with shaping his naval ambitions. Kaiser Wilhelm II summoned Mahan to Berlin. Winston Churchill studied it obsessively. This is the intellectual foundation upon which world powers built their naval doctrines, a treatise that transformed how nations understood the relationship between sea lanes and sovereignty.
