With this Act of Congress, the United States declared war on Great Britain in the War of 1812.
For the early decades of the nation’s history, relations between the United States and Great Britain had remained strained. Their relationship deteriorated sharply with the outbreak of war in Europe in 1803. Britain imposed a blockade on neutral countries such as the United States. In addition, the British took American sailors from their ships and “impressed” them into the British Navy.
In Congress, southern and western Democratic-Republican “War Hawks,” such as the new Speaker of the House, Henry Clay of Kentucky, and Representative John C. Calhoun of South Carolina, led the sentiment for war, calling for a defense of American interests and honor. On June 1, 1812, President James Madison asked for a declaration of war. Shortly afterward, Congress, despite the opposition of every Federalist, approved the declaration.
