A main village of the Seneca Indians was at Kanadasaga, now Geneva, while Cayugas occupied the region to the east. In retaliation for raids by Iroquois Indians on the New York frontier during the American Revolution, the Sullivan-Clinton Expedition of 1779 devastated these Indian villages. Veterans of the campaign returned to the area, and the eastern portion was included in the Military Tract, land set aside as a bounty for former soldiers. The western Finger Lakes area was part of the Phelps-Gorham Purchase. Settlement started in 1787 and increased rapidly after 1790.
