 The Seneca people, who were part of the "Haudenosaunee", or Iroquois Confederacy based in New York, defeated them.The Seneca had ranged south while seeking new hunting grounds through the Shenandoah Valley to the West.At the Treaty of Albany in 1718, the Iroquois Five Nations ceded control of their land east of the Blue Ridge Mountains, including Lynchburg, to the Colony of Virginia; they confirmed this in 1721.
