History of Maine - The Aroostook War

The Aroostook War

The still-lingering border dispute with British North America came to a head in 1839 when Maine Governor John Fairfield declared virtual war on lumbermen from New Brunswick cutting timber in lands claimed by Maine. Four regiments of the Maine militia were mustered in Bangor and marched to the border, but there was no fighting. The Aroostook War was an undeclared and bloodless conflict that was settled by diplomacy.

U.S. Secretary of State Daniel Webster secretly funded a propaganda campaign that convinced Maine leaders that a compromise was wise; Webster used an old map that showed British claims were legitimate. The British had a different old map that showed the American claims were legitimate, so both sides thought the other had the better case. The final border between the two countries was established with the Webster–Ashburton Treaty of 1842, which gave Maine most of the disputed area, and gave the British a militarily vital connection between its provinces of Canada (present-day Quebec and Ontario) and New Brunswick.

The passion of the Aroostook War signaled the increasing role lumbering and logging were playing in the Maine economy, particularly in the central and eastern sections of the state. Bangor arose as a lumbering boom-town in the 1830s, and a potential demographic and political rival to Portland. Bangor became for a time the largest lumber port in the world, and the site of furious land speculation that extended up the Penobscot River valley and beyond.
