After the 18th-century wars of 1711–1713 (known as the Tuscarora War) against English colonists and their Indian allies, most of the surviving Tuscarora left North Carolina and migrated north to Pennsylvania and New York, over a period of 90 years. They aligned with the Iroquois in New York, because of their ancestral linguistic and cultural connections. Sponsored by the Oneida, they were accepted in 1722 as the Sixth Nation of the Iroquois Confederacy, or "Haudenosaunee". After the American Revolution, in which they and the Oneida allied with the colonists, the Tuscarora shared reservation land with the Oneida before gaining their own. The Tuscarora Nation of New York is federally recognized.
