The Aroostook War (sometimes called the Pork and Beans War) was a confrontation in 1838–1839 between the United States and the United Kingdom over the international boundary between the British colony of New Brunswick and the US state of Maine. Top-level diplomats from the US and Britain met in Washington and forged a peaceful compromise, the Webster-Ashburton Treaty in 1842, which fixed the permanent border. The term "war" was rhetorical; local militia units were called out but never engaged in combat. The event is best described as an international incident.
