What is the Webster Ashburton Treaty?

The Webster-Ashburton Treaty, signed in 1842 between the United States and Great Britain, resolved several border disputes between the two nations, particularly in the northeastern U.S. and Canada. It established the boundary between the U.S. and British North America (now Canada) in the Maine-New Brunswick region and addressed issues related to the slave trade. The treaty is significant for helping to improve Anglo-American relations and providing a framework for future diplomatic negotiations.
