Senneca Holdings history

1735, Ganawaugus, New York, United States—died August 10, 1815, Onondaga), Seneca chief and prophet who founded the religious movement known as Gai’wiio (“Good Message”) among the Iroquois Indians of North America in the early 19th century.

In 1817 the United States established two reservations for the Ohio "Seneca." One was for the Seneca of Sandusky, a mingling of Cayuga, Erie, Conestoga, and others, along the Sandusky River, and the second was for a consolidated band of Seneca and Shawnee at Lewistown.

What remained of the Seneca tribes moved westward, and in 1831 they signed a treaty agreeing to cede what remained of their lands in New York and Ohio to the federal government and relocate southwest of Missouri, in what is present-day Oklahoma.

Approximately 358 Seneca of Sandusky reached the Cowskin (Elk) River in present Delaware County, Oklahoma, in summer 1832.

In 1848 the incompetence and corruption of the hereditary chiefs, in particular their surrender of tribal land to non-Indians, caused the Seneca to change their form of government to a republic.

The United States government separated the Seneca from the Shawnee in 1867.

In 1937, the Ohio Seneca, Ohio Seneca-Cayuga and the Ohio Cayuga became federally recognized as the Seneca-Cayuga of Oklahoma.
