On May 15, 1636, William Pynchon purchased land on both sides of the Connecticut River from the local Pocomtuc Indians known as Agawam, which included present-day Springfield, Chicopee, Longmeadow, and West Springfield, Massachusetts. The purchase price for the Agawam portion was 10 coats, 10 hoes, 10 hatchets, 10 knives, and 10 fathoms of wampum. Agawam and West Springfield separated from Springfield to become the parish of West Springfield in 1757; Agawam and West Springfield split in 1800. Agawam incorporated as a town on May 17, 1855.
