In the record

The atlas records 2 broken treaty promises involving Seneca Nation of Indians: Treaty of Buffalo Creek (1838): sale of Seneca reservations and the 1842 and 1857 corrections and Canandaigua 1794 and the Kinzua Dam (1958-1965). One court case turned on its rights: Seneca Nation (Kinzua Dam litigation).

The records group it with Haudenosaunee (Six Nations). This nation carries the history of Seneca in the treaty record.
