trespassers overran Indian lands. There were repeated conflicts between settlers and members of the tribes. The U.S. government brought the tribes to council again in 1867 to achieve peace under the Medicine Lodge Treaty. It promised the Arapaho a reservation in Kansas, but they disliked the location. They accepted a reservation with the Cheyenne in Indian Territory, so both tribes were forced to remove south near Fort Reno at the Darlington Agency in present-day Oklahoma. The Dawes Act broke up the Cheyenne-Arapaho land base. All land not allotted to individual Indians was opened to settlement in the Land Run of 1892. The Curtis Act of 1898 dismantled the tribal governments in an attempt to have the tribal members assimilate to United States conventions and culture. After the Oklahoma Indian Welfare Act passed in 1936, the Cheyenne and Arapaho organized a single tribal government in 1937. The Indian Self-Determination Act of 1975 further enhanced tribal development. Economic development The tribe operates three tribal smoke shops and five casinos: the Lucky Star Casino in Clinton, the Lucky Star Casino in Concho, the Lucky Star Casino in Watonga, the Lucky Star Casino in Hammon, and the Lucky Star Casino in Canton. They also issue their own tribal vehicle tags. Their economic impact is estimated at $32 million. Government The Cheyenne and Arapaho Tribes are headquartered in Concho, Oklahoma. Of 12,185 enrolled tribal members, 8,664 live within the state of Oklahoma. The tribal jurisdictional area includes Beckham, Blaine, Canadian, Custer, Dewey, Ellis, Kingfisher, Roger Mills, and Washita Counties. The tribal government consists of the Tribal Council, Executive Branch, Legislative Branch, and Judicial Branch. The Tribal Council includes all tribal members over the age of 18. The Executive Branch is led by the Governor and Lieutenant Governor. The Legislative Branch is made up of legislators from the four Arapaho districts and four Cheyenne districts. The Judicial Branch includes a Supreme Court, including one Chief Justice and four Associate Justices; a Trial Court, composed of one Chief Judge and at least one Associate Judge; and any lower courts deemed necessary by the Legislature. In 2006 the tribes voted and ratified the Cheyenne and Arapaho Tribes Constitution which replaced the 1975 constitution. Institutions The Cheyenne and Arapaho Tribal Tribune is the tribe's newspaper.
