Rush-Bagot Pact, 1817 and Convention of 1818 The Rush-Bagot Pact was an agreement between the United States and Great Britain to eliminate their fleets from the Great Lakes, excepting small patrol vessels. The Convention of 1818 set the boundary between the Missouri Territory in the United States and British North America (later Canada) at the forty-ninth parallel. Both agreements reflected the easing of diplomatic tensions that had led to the War of 1812 and marked the beginning of Anglo-American cooperation.
