The boundary dispute over the Oregon territory began after which two nations claimed the area

Answer 1

The boundary dispute over the Oregon Territory began after the United States and Great Britain both claimed the area. The conflict primarily centered around conflicting claims to the land, with the U.S. expanding its territory westward and Britain asserting its rights based on earlier explorations and treaties. The dispute was eventually settled with the Oregon Treaty of 1846, which established the boundary at the 49th parallel.
