A. Great Britain

In 1846, the United States and Great Britain agreed to a joint occupation of the Oregon Country, which included present-day Oregon, Washington, and Idaho, as well as parts of Montana and Wyoming. This agreement followed the withdrawal of Russia from the region, which had previously claimed the land south of Alaska. The joint occupation lasted until 1848, when the two countries signed the Oregon Treaty, which established the 49th parallel as the boundary between the United States and British North America.
