The Mashantucket Pequot are a federally recognized Native American nation in the state of Connecticut. They are descended from the Pequot people, one of the Algonquian-languages family. Within their Reservation in Ledyard, New London County, Connecticut, the Mashantucket Pequot operate Foxwoods Resort Casino. It is the world's largest resort casino in terms of gambling space and number of slot machines, and until 2007 one of the most economically successful. By 2012 it was deeply in debt. In the course of its successful federal land claims suit against the state, the tribe achieved federal recognition in 1983 by an act of Congress, as part of the settlement of the suit. It was the eighth tribal nation to have gained recognition through the political rather than administrative process. Tribal membership is based on proven descent from tribal members listed in the 1900 Census. They are one of two federally recognized tribes in Connecticut; the other are the Mohegan Indian Tribe.
