How did Britain and America settle boundary disputes over the Maine and Canadian boundary?

Britain and America settled boundary disputes over Maine and the Canadian border through the Webster-Ashburton Treaty of 1842. This agreement resolved various territorial disputes, including the northeastern boundary, by establishing a clear line that was acceptable to both parties. The treaty was facilitated by diplomatic negotiations and aimed to improve relations between the two nations after tensions arose from competing claims. It ultimately created a more defined border, reducing potential conflict over the territory.
