What was the outcome of Polk's compromise with Britain concerning Oregon?

The outcome of Polk's compromise with Britain concerning Oregon was significant in shaping the borders of the United States. By dividing the Oregon Territory along the 49th parallel, the United States and Britain were able to peacefully settle their territorial disputes in the region. This compromise allowed the U.S. to gain control of the present-day states of Oregon, Washington, and parts of Idaho, while Britain retained control of the area that would become British Columbia. The agreement reflected Polk's expansionist goals and helped avoid potential conflict between the two nations, allowing both to focus on other priorities, such as the conflict with Mexico. This resolution highlights the United States' growing influence and territorial ambitions in the 19th century, illustrating the nation's desire to expand westward.
