"The Influence of Sea Power upon History" is a seminal work by Alfred Thayer Mahan, published in 1890. Mahan argued that a nation's strength and global influence are closely tied to its naval power. He emphasized the importance of a strong navy, control of trade routes, and the establishment of overseas bases to project power and secure national interests. Mahan's ideas significantly shaped naval strategy and policy in the late 19th and early 20th centuries. His theories influenced major powers, including the United States and Great Britain, leading to naval expansions and the development of modern fleets, ultimately impacting global geopolitics.
