In 1848, Chicopee, which for more than two centuries had been a part of the Town of Springfield, was separated and organized as a distinct town. Political factions in Springfield wanted that jurisdiction to remain a town, rather than become a city and take on a mayoral form of government. By partitioning Chicopee, those political factions prevented Springfield from becoming a city until 1852. The result was that Springfield lost 2/5 of its land area and nearly half of its population when Chicopee was created.
