Joint control steadily grew less tolerable for both sides. After a British minister rejected the offer of U.S. Presidents James K. Polk and John Tyler to settle the boundary at the 49th parallel north, American expansionists called for the annexation of the entire region up to Parallel 54°40′ north.

However, after the outbreak of the Mexican–American War in April 1846 diverted U.S. attention and military resources, a compromise was reached in the ongoing negotiations in Washington, D.C., and the matter was then settled by the Polk administration  to avoid a two-war situation, and another war with the formidable military strength of Great Britain.

The treaty was negotiated by US Secretary of State James Buchanan and Richard Pakenham, British envoy to the United States. Foreign Secretary Earl of Aberdeen was responsible for it in Parliament. The treaty was signed on June 15, 1846, ending the joint occupation and making Oregonians south of the 49th parallel American citizens, with those north of it becoming British.
