The villages of Cabotville, Chicopee Falls, Willimansett, and Fairview (and the lands that would become Aldenville) remained a part of Springfield, Massachusetts, from 1636 until 1848, when they were partitioned to form the Town of Chicopee. Political factions in Springfield had wished to keep Springfield a "town," instead of becoming a "city," which would give it a mayoral form of government. To keep Springfield sufficiently unpopulated to subvert a state regulation that would have required it to become a city, they partitioned Chicopee, which contained approximately 2/5 of Springfield's land area, and nearly half of its population.
