Choctaw Nation of Oklahoma

The Choctaw Nation of Oklahoma (Choctaw: Chahta Okla) is a federally recognizedNative American tribal nation with an Indian reservation encompassing portions of Southeastern Oklahoma in the United States.

The Choctaw Nation of Oklahoma (CNO) is one of three federally recognized tribes of Choctaw people, an Indigenous people of the Southeastern Woodlands. The other two are the Mississippi Band of Choctaw Indians and Jena Band of Choctaw Indians in Louisiana. The U.S. federal government forcibly removed the Choctaw Nation of Oklahoma from their Mississippi homelands in 1831 to 1833 to Indian Territory, later to become Oklahoma. A smaller group of Mississippi Choctaw were coerced to migrating to Oklahoma in 1908.

The Choctaw Nation of Oklahoma is the third-largest tribe in the United States with more than 225,000 tribal citizens. A total of 233,126 people live within these boundaries, with its tribal jurisdictional area comprising 10.5 counties in the state.

At roughly 6,952,960 acres (28,138 km; 10,864 sq mi), the Choctaw Nation's reservation is the second-largest in area after the Navajo Nation, exceeding that of the seven smallest U.S. states (Rhode Island, Delaware, Connecticut, New Jersey, New Hampshire, Vermont, and Massachusetts). The reservation borders with the reservations of the Chickasaw Nation, Muscogee (Creek) Nation, and Cherokee Nation, as well as the U.S. states of Texas and Arkansas. The original territory has expanded and shrunk several times since the 19th century, reaching its current boundaries in 1867. The seat of government is located in Durant, Oklahoma.
