U.S. Congress Declares War on Great Britain
Tensions between the young United States and Britain had escalated over maritime rights, including the impressment of American sailors into the Royal Navy and British restrictions on neutral trade during the Napoleonic Wars. Western and Southern members of Congress also cited British support for Native American resistance on the frontier as provocation. After months of debate, the House of Representatives voted 79-49 in favor of war on June 4, followed by the Senate's narrower 19-13 approval on June 17. President James Madison signed the declaration into law on June 18, 1812, marking the first formal U.S. declaration of war under the Constitution. The conflict would last until 1815 and test the young nation's military and political cohesion.
