The Mashantucket Pequot Tribal Nation is a federally recognized American Indian tribe in the state of Connecticut. They are descended from the Pequot people, an Algonquian-language tribe that dominated the southern New England coastal areas, and they own and operate Foxwoods Resort Casino within their reservation in Ledyard, Connecticut. As of 2018, Foxwoods Resort Casino is one of the largest casinos in the world in terms of square footage, casino floor size, and number of slot machines, and it was one of the most economically successful in the United States until 2007, but it became deeply in debt by 2012 due to its expansion and changing conditions.
