Hampshire County, Massachusetts (Continental Congress)

Hampshire County was created on 7 May 1662 from Middlesex County's previously unorganized territory comprising the entire western part of the Massachusetts Bay Colony. Hampshire County included the original towns of Springfield, Northampton, and Hadley. By 1683, three new towns (Westfield (now Southwick), Suffield, and Enfield) had been incorporated south of Springfield. These towns were partly or wholly in the modern state of Connecticut at the time of their incorporation and resulted in a border dispute between the Connecticut Colony and Massachusetts Bay Colony. The original Hampshire County included territory that is now in modern day Worcester County, set off on 5 April 1731, Berkshire County, set off on 28 May 1760, Franklin County, set off on 24 June 1811 and Hampden County, set off on 25 February 1812.
