The Oregon Territory stretched from the Pacific coast to the Rocky Mountains, encompassing the area including present-day Oregon, Washington, and most of British Columbia. Originally Spain, Great Britain, Russia, and the United States claimed the territory. In 1819, under terms of the Transcontinental Treaty, Spain ceded its claims to the territory to the United States. Shortly thereafter the United States contested a unilateral Russian move to grant its citizens a fishing, whaling, and commercial monopoly from the Bering Straits to the 51st parallel.
In 1818, a U.S.-British agreement had established the border along the 49th parallel from Lake of the Woods in the east to the Rocky Mountains in the west. The two nations also agreed to a joint occupation of Oregon territory for 10 years, an arrangement that was extended for an additional 10 years in 1827.
