The agreements made during the Convention of 1818 and the setting of the 49th parallel were indefinitely extended in 1827. However, by the middle 1840s the political policies of Great Britain and America had changed. U.S. immigration had increased and America wanted to claim the entire territory. This led to a renegotiation of the agreements made in the Convention of 1818.

The next issue was over the question of whether Oregon should be free soil or slave soil.
