Alfred Thayer Mahan (1840-1914) was a preeminent American naval historian and strategist whose work has had a profound influence on naval theory across the world. A graduate of the United States Naval Academy at Annapolis, he went on to serve as a Union naval officer during the American Civil War. His experiences at sea and prodigious intellectual pursuits culminated in his becoming a lecturer and then president of the Naval War College in Newport, Rhode Island. Mahan's literary contributions were vast, but it is his seminal work, 'The Influence of Sea Power upon History, 1660-1783,' that firmly established his reputation as a notable historian and strategic thinker. The ability to contextualize naval warfare within the broader strokes of international relations and national power distinguished Mahan among his peers. In his follow-up, 'The Influence of Sea Power upon the French Revolution and Empire: 1793-1812,' Mahan further explored the critical role of naval power in global politics and warfare, providing a detailed account of naval operations and their implications for the success of the French Revolution and the fate of Napoleon's Empire. His emphasis on the importance of sea control and the development of a dominant naval force influenced naval policies worldwide, marking an inflection point in maritime strategy that persists to this day.
