What was the outcome of the convention of 1818?

The convention of 1818 resulted in the establishment of the 49th parallel as the northern boundary between the United States and British North America (now Canada). This agreement was significant as it provided a clear and defined border stretching from the Lake of the Woods to the Rocky Mountains, resolving ongoing territorial disputes from earlier treaties. It played a pivotal role in the expansion of the United States and set the stage for future negotiations regarding the westward expansion of the nation.

The choice reflects the diplomatic efforts of the time to find peaceful resolutions to boundary conflicts, facilitating further westward expansion while maintaining a stable relationship with Britain. This agreement is often viewed as a successful accomplishment in American foreign policy following the War of 1812, aligning with the nation's growing nationalistic sentiment and desire for expansion.
