The War of 1812, often referred to as "The Forgotten War" or the "Second War of Independence," was a conflict between the United States and Great Britain that took place from 1812 to 1815.

British impressment of American sailors into the Royal Navy was a major grievance. The British practice of stopping American ships and forcing sailors into service for the British navy angered many Americans. Britain and France imposed trade restrictions on the United States during the Napoleonic Wars.

British support for Native American resistance against American expansion in the Northwest Territory contributed to tensions. The British were accused of arming and encouraging Native American attacks against American settlers.
