The expansion of the US navy was significantly influenced by the writings of Captain Alfred Mahan, particularly his seminal work “The Influence of Sea Power Upon History, 1660-1783.” Mahan argued that naval strength was crucial for national greatness and advocated for a powerful navy to protect American interests, particularly in expanding global trade and asserting influence. His ideas resonated during the late 19th and early 20th centuries, leading to a heightened sense of urgency to modernize and expand the navy. This emphasis on sea power helped to catalyze naval expansion, ultimately influencing U.S. foreign policy and military strategy, which included the construction of modern battleships and the establishment of overseas bases.
