Between 1890 and 1913, Captain Alfred Thayer Mahan published a series of books on naval warfare in the age of sail, which established his reputation as the founder of modern strategic history. But Mahan's two principal arguments have been gravely misunderstood ever since, according to Jon Tetsuro Sumida. Instead of representing Mahan as an advocate of national naval supremacy, Sumida shows him asserting that only a multinational naval consortium could defend international trade. Instead of presenting Mahan as a man who adhered to strategic principles, Sumida shows that he stressed the importance of an officer's judgment and character formed by the study of history. Inventing Grand Strategy and Teaching Command includes a subject index to all Mahan's published books and an extensive bibliography.
