The Treaty of 1818 between the US and Britain stated the Oregon Country would be jointly occupied by the US and Britain. But it resulted in disputes between Americans and British and another treaty, the Oregon Treaty, was signed in 1846. It stated the Oregon Country would be divided in two. The US would get all the land south of the 49th parallel (which eventually became the states of Washington and Oregon) and the British would get all the land north of the 49 parallel (which became British Columbia). Except for Vancouver Island off the coast of the Oregon Country, 4/5's of Vancouver Island was north of the 49th parallel so the US said Britain could have all of it instead of splitting it at the 49th parallel.
The cause of the U.S. participation was pirates from the Barbary States seizing American merchant ships and holding the crews for ransom, demanding the U.S. pay tribute to the Barbary rulers. United States President Thomas Jefferson refused to pay this tribute. Sweden had been at war with the Tripolitans since 1800.
