After the Crown's defeat, Britain ceded control of its territory in the lower colonies to the new United States, including the lands controlled by the Iroquois nations. In addition, due to the ferocity of the war in New York, most residents wanted the Indians expelled even though two nations had supported the rebels. The Seneca and other Iroquois nations were forced to cede most of their lands to the US. In the Treaty of Canandaigua, the Seneca negotiated the right to keep five plots: the territory around Oil Springs and the Allegheny River, the land surrounding Cattaraugus Creek, the former Neutral lands around Buffalo Creek, and their primary site of what is now known as the Tonawanda Reservation.
