 the term treaty of hartford applies to three historic agreements negotiated at hartford, connecticut. the 1638 treaty divided the spoils of the pequot war. the 1650 treaty defined a border between the dutch new netherland and english settlers in connecticut and also defined a border between dutch and english settlers on long island. in the 1786 treaty new york and massachusetts reached an agreement on their claims of the western land. ==1638 treaty== 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 massachusetts bay colony, the connecticut river colony, the mohegan and narragansett tribes participated in the treaty. surviving pequot prisoners were divided between the tribes; 40 percent each and the remaining 20 percent awarded to tribes on long island who had supported the narragansett. the pequot lands went to the connecticut river towns. the other major feature of this treaty was to outlaw the pequot language and 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. ==1650 treaty==  in 1650, dutch director-general of new netherland petrus stuyvesant went to hartford to negotiate a border with the governor of english connecticut colony edward hopkins. the dutch colony of new netherland was feeling increased pressure from the rising number of english colonists at its borders. stuyvesant traded connecticut land claims (the new netherland claim encompassed the full length of the connecticut river and as far east as narragansett bay) in order to get a clear boundary on long island. they agreed on a connecticut line 50 dutch miles west of the mouth of the connecticut river. on long island, a line would be drawn south from the westernmost point of oyster bay, through modern nassau county. in practice, the treaty simply reflected changed facts on the ground. settlement of the dutch colony had clustered around the hudson river with only isolated trading posts on the connecticut (including fort hoop which would become hartford, connecticut). the exploding population of new england, and the splintering impulses of its religious-based colonies, had led to significant english settlement in the connecticut river valley, along the coast of long island sound and on eastern long island. back in europe, the dutch west india company approved the treaty, but the english government, which rejected all dutch claims in north america as illegitimate, did not. in america, however,
