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.
The region later known as Oregon Country had been claimed by the United States, Great Britain, Russia and Spain, by the early 1800s. A treaty called the Convention of 1818 was signed between the United States and Britain agreeing to joint occupation of the Oregon Country.Spain gave up its claim in the region in the Adams-Onis Treaty of 1819, and Russia gave up its claim in 1825.he territory now forms part of the present day Canadian province of British Columbia and the US-states of Oregon and Washington.
