Maine Boundary Dispute

The Maine Boundary Dispute was a disagreement between the United States and Britain over the border between Maine and British Canada (now Quebec and New Brunswick) in the 19th century. The conflict centered on where the boundary line should be drawn, as both countries claimed parts of the territory based on different maps and interpretations of treaties. The dispute was resolved peacefully by the Treaty of Washington in 1842, which established the current border, helping to avoid potential conflict and clarifying the territorial boundaries between the two nations.
