The land cessions were accomplished through a series of purchases and treaties negotiated between the Haudenosaunee and the Province of New York (and after the American Revolution, the United States government) between 1682 and 1797.
In the Nanfan Treaty of 1701, the Haudenosaunee had ceded their lands north and west of the Ohio River to the Thirteen Colonies, which were in part obtained from the Beaver Wars in the late 17th century.
During the period of Indian removal in the early 19th century by the U.S. government, a majority of the Oneida, one of the tribes which made up the Haudenosaunee, migrated to the state of Wisconsin.
[citation needed] Between 1682 and 1684, Quaker writer and settler William Penn acquired as many as ten individual deeds from the Lenape to territory in colonial Pennsylvania, which formed present-day Chester, Philadelphia, and Bucks counties.
[1] The treaty renewed the Covenant Chain and agreed to recognize the Blue Ridge Mountains as the demarcation between colonial Virginia and the territory of the Haudenosaunee.
[citation needed] Various colonial governments proved unable to prevent white settlers from moving beyond the Blue Ridge Mountains and settling in the Shenandoah Valley in the 1730s.
