Aroostook War

The Aroostook War, or the Madawaska War, was a military and civilian-involved confrontation in 1838–1839 between the United States and the United Kingdom over the international boundary between the British colonies of New Brunswick and Lower Canada and the U.S. state of Maine. The term "war" was rhetorical; local militia units were called out but never engaged in actual combat. The event is best described as an international incident.
