15 jun 1846 ano - Oregon Treaty

Descrição:

A treaty between the US and British Canada that set the border between the two countries at the 49th parallel. Previously, the Oregon Country was composed of territories from modern-day Oregon, Washington, Idaho, and parts of Wyoming, Montana, and British Canada, and was jointly occupied between the US and Great Britain. The treaty granted Great Britain the land above the 49th parallel, while the US acquires the land below it. However, Polk's supporters were less than pleased with this arrangement, as the president had previously promised the country all of the territory south of the 54°40' parallel. This dispute gave rise to the slogan "54°40' or fight!" However, the agreement was not changed and the land above the 49° was ceded to the British.
