<Ul> <Li> </Li> <Li> </Li> <Li> </Li> </Ul> <P> The War of 1812, a war between the United States, Great Britain, and Britain's Indian allies, lasted from 1812 to 1815 . The U.S. declared war and historians have long debated the multiple factors behind that decision . </P> <P> There were several causes for the U.S. declaration of war: First, a series of trade restrictions introduced by Britain to impede American trade with France, a country with which Britain was at war (the U.S. contested these restrictions as illegal under international law); second, the impressment (forced recruitment) of U.S. seamen into the Royal Navy; third, the British military support for American Indians who were offering armed resistance to the expansion of the American frontier to the Northwest; fourth, a possible desire on the part of the United States to annex Canada . An implicit but powerful motivation for the Americans was the desire to uphold national honor in the face of what they considered to be British insults (such as the Chesapeake affair). </P> <P> American expansion into the Northwest (Ohio, Indiana, Michigan, Illinois and Wisconsin) was impeded by Indian raids . Some historians maintain that an American goal in the war was annex some or all of Canada, a view that many Canadians still share, while others argue that inducing the fear of such a seizure had merely been a U.S. tactic designed to obtain a bargaining chip . Some members of the British Parliament at the time and dissident American politicians such as John Randolph of Roanoke claimed that land hunger rather than maritime disputes was the main motivation for the American declaration . However, some historians, both Canadian and American, retain the view that desire to annex all or part of Canada was an American goal . Although the British made some concessions before the war on neutral trade, they insisted on the right to reclaim their deserting sailors . The British also had the long - standing goal of creating a large "neutral" Indian state that would cover much of Ohio, Indiana and Michigan . They made the demand as late as 1814 at the peace conference, but lost battles that would have validated their claims . </P>
