“Impressment of American Seamen,” wood engraving after a drawing by Howard Pyle, Harper’s Monthly, April 1884
Great Britain frequently captured English deserters on American vessels and forced them into service with the Royal Navy. This impressment was one motivation for Congress to declare war.

War of 1812: Congress Declares War
The 1783 treaty that ended the American Revolution did not resolve conflict between the United States and Great Britain. Tensions escalated over Great Britain’s impressment of American sailors, interference with trade, occupation of U.S. territory, and relations with American Indians. In June 1812 Speaker of the House Henry Clay persuaded Congress to use its constitutional power to declare war for the first time. When President James Madison signed the declaration into law, the United States and Great Britain were again at war.
