Rush-Bagot Treaty
The Rush-Bagot Treaty signed in 1817 between the United States and the United Kingdom provided the basis for an unguarded boundary between the US and British North America and demilitarization of the Great Lakes and Lake Champlain, where many British naval armaments and forts still remained. This agreement was indicative of improving relations between the United States and Britain during this time period following the end of the War of 1812.It laid the groundwork for and eventually led to the Treaty of Washington of 1871, which completed the job of disarmament.
This treaty marked the end of unofficial fighting (known informally as the Lumberjack's War) along the Maine-Nova Scotia border. The border was fixed with the disputed territory divided among the two nations. Also, as a result of this treaty, portions of the western US-Canada border were adjusted so as to be consistant. It gave the US negligably more land to the north; gold was later discovered on this land.
