John H. Schroeder chronicles the expansion of the American Navy's peacetime role in developing the nation's overseas commercial empire during the thirty years before the Civil War. He demonstrates how the rapid acceleration of American commercial activity around the world increased pressure on the Navy to meet new economic and political demands. He analyzes how the Navy's haphazard development in the antebellum years paralleled and interacted with commercial activity, and how the end result impacted dramatically on the economic development of the United States.
