Fifty-Four Forty or Fight!

Fifty-Four Forty or Fight was a campaign slogan used by presidential candidate James K. Polk during the Election of 1844. The slogan referred to the boundary dispute the United States had with Great Britain over the Oregon Country. 54 degrees, 40 minutes North Latitude was the northernmost region of the disputed area, including all of modern British Columbia. Polk was eventually elected President, but the 49th Parallel was compromised upon.
