Alfred Thayer Mahan (1840–1914) was an American naval officer, considered one of the most important naval strategists of the nineteenth century. In 1885 he was appointed Lecturer in Naval History and Tactics at the US Naval War College, and became President of the institution between 1886–1889. This highly influential volume, first published in 1890, contains Mahan's analysis of naval warfare and tactics between 1660–1783. Mahan discusses and analyses the factors which led to Britain's naval domination during the eighteenth century, and recommends various naval strategies based on these factors. His work was closely studied by contemporary military powers, with his tactics adopted by many major navies in the years preceding the First World War. This volume is considered one of the most influential published works on naval strategy, and is invaluable for the study of naval warfare both before and during the First World War.
