On June 18, 1812, President James Madison declared war on Great Britain. His declaration led to a three-year war that is, according to some, the Colonies' true war for independence. The War of 1812 ended on December 24 with the Treaty of Ghent.
The first battle, though not actually part of the War of 1812, occurred on November 7, 1811 between General Harrison's forces and Tecumseh's forces. It ended with Tecumseh's defeat. The final battle occurred on January 8 in New Orleans.
The "Star Spangled Banner" was also inspired by events during the War of 1812, Napoleon was defeated, and Washington was burned.
