In the mid-nineteenth century, many Americans wanted to see the United States’ territory expand northward into the area now known as Canada. The phrase “fifty-four forty or fight” referred to the desire to move the boundary northward to 54°40’ North, which would have encompassed much of southern Canada. Ultimately, the boundary was fixed at 49° North, where it sits today.
