Seneca is one of the languages of the Haudenosaunee (Iroquois Confederacy). Around 200 speakers of Seneca remain, most in New York state. Mingo, a dialect of Seneca, is spoken in the West Virginia region by a group of Seneca who left the Haudenosaunee. Though Mingo and standard Seneca are mutually comprehensible, political distinctions have led many to treat it as a separate language.
