The War of 1812 was a battle fought between the United States and Great Britain, along with help from Canada and Native Americans, from June 18, 1812 to February 18, 1815. The United States declared war on Great Britain due to multiple disputes that included trade restrictions against the United States, the capture of American sailors, and the support of Native American tribes fighting against the American colonists. These problems led to the War of 1812, which Americans eventually declared the “Second Revolutionary War.” Britain's main goal was to defend the North American colonies, but they also wanted to create a neutral Indian buffer state in the Midwest. As a colony of Great Britain, Canada fought in the war while being invaded by the Americans. Native Americans fought against the United States because they did not want the Americans to expand westward. These groups joined forces during the War of 1812 to prevent the United States from becoming a major force in the world. Trade restrictions brought about by Britain's war with France helped start the War of 1812. France and Britain were already at war. France did not allow America to trade with Great Britain, and Great Britain did not allow America to trade with France.
