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

Answer 1

The boundary dispute over the Oregon Territory primarily involved the United States and Great Britain. This disagreement arose in the early 19th century as both nations claimed rights to the land, which stretched from the Pacific Coast eastward to the Rocky Mountains, and from California north to the present-day Canadian border. The dispute was ultimately resolved in 1846 with the Oregon Treaty, which established the 49th parallel as the boundary between the two countries.
