The War of 1812 was fought between the United States and Great Britain and lasted from 1812 to 1815. Resulting from American anger over trade issues, impressment of sailors, and British support of Indigenous attacks on the frontier, the conflict saw the US Army attempt to invade Canada while British forces attacked south.

The War of 1812 (18 June 1812 – 17 February 1815) was fought by the United States and its indigenous allies against the United Kingdom and its own indigenous allies in British North America, with limited participation by Spain in Florida. It began when the United States declared war on 18 June 1812.
