The Treaty of Fort Stanwix was a treaty signed between representatives from the Iroquois and Great Britain (accompanied by negotiators from New Jersey, Virginia and Pennsylvania) in 1768 at Fort Stanwix. It was negotiated between Sir William Johnson, his deputy George Croghan, and representatives of the Iroquois.

The treaty established a Line of Property following the Ohio River that ceded the Kentucky portion of the Virginia Colony to the British Crown, as well as most of what is now West Virginia. The treaty also settled land claims between the Iroquois and the Penn family; the lands acquired by American colonists in Pennsylvania were known as the New Purchase.

Treaty

The purpose of the conference was to adjust the boundary line between Indian lands and the Thirteen Colonies outlined in the Royal Proclamation of 1763. The British government hoped a new boundary line might bring an end to the rampant frontier violence between Native Americans and American colonists. Native Americans hoped a new, permanent line might prevent further encroachment of their lands from the colonists.

The final treaty was signed on November 5 with one signatory for each of the Six Nations and in the presence of representatives from the colonies of New Jersey, Virginia and Pennsylvania as well as Johnson. The Native American nations present received gifts and cash totaling £10,460 7s. 3d. sterling, the highest payment ever made from the British Crown to Native Americans. The treaty established a Line of Property which extended the earlier proclamation line of the Alleghenies (the divide between the Ohio and coastal watersheds), much farther to the west. The line ran near Fort Pitt and followed the Ohio River as far as the Tennessee River, effectively ceding the Kentucky portion of the Virginia Colony to the Crown, as well as most of what is now West Virginia.
