The Treaty of Hartford is a treaty concluded between England, the Mohegan and the Narragansett on September 21, 1638 in Hartford, Connecticut.
The Pequot War of 1636 and 1637 saw the virtual elimination of the Pequot Indians. The victors (English colonists and their Native American allies) met to decide on the division of the fruits of victory.
The Mohegan and Narragansett tribes and the three English settlements that would become the Connecticut River Colony in 1639, participated in the treaty. Surviving Pequot prisoners were divided between the tribes; each tribe received 80 captives, with 20 captives being awarded to Ninigret, a sachem of the Eastern Niantic who were allied with the Narragansett.
The Pequot lands went to the Connecticut River towns. The other major feature of this treaty was to outlaw the Pequot name. Any survivors would be referred to in the future as Mohegans or Narragansett. No Pequot town or settlement would be allowed. This treaty was signed on September 21, 1638.
