Although neither Britain nor the U.S. was able to secure major concessions through the Treaty of Ghent, it nevertheless had important consequences for the future of North America. The withdrawal of British troops from the Northwest Territory and the defeat of the Creeks in the South opened the door for unbounded U.S. expansionism in both regions. The treaty also established measures that would help arbitrate future border disputes between the U.S. and Canada, perhaps one reason why the two countries have been able to peaceably share the longest unfortified border in the world ever since.
