Which territory was at some point claimed by Spain, Great Britain, Russia, and the United States, and was eventually split between Great Britain and the United States?

Spain, Great Britain, Russia, and the United States all at some point claimed the Oregon Territory. Spain and Russia eventually relinquished their claims, leaving Great Britain and the United States each laying claim to the territory. In 1846, the territory was officially split at the 49th parallel, with Great Britain gaining the territory north of that divide, and the United States gaining the territory south of it.
