War of 1812 Flag
June 18, 1812 – War of 1812 Began
On June 1, 1812, President James Madison sent a message to Congress recounting American grievances against Great Britain, though not specifically calling for a declaration of war. After Madison’s message, the House of Representatives deliberated for four days behind closed doors before voting 79 to 49 (61% in favor) the first declaration of war, and the Senate agreed by 19 to 13 (59% in favor). The conflict began formally on June 18, 1812, when Madison signed the measure into law and proclaimed it the next day. This was the first time that the United States had declared war on another nation, and the Congressional vote would prove to be the closest vote to formally declare war in American history.
