This organization was formed by an intertribal group which met at El Reno and included Mack Haag (Cheyenne) of Calumet, Sidney White Crane of Kingfisher, Charles W. Dailey (Oto), George Pipestem (Oto), and Charles E. Moore (Oto), all of Red Rock, Frank Eagle (Ponca) of Ponca City, Wilbur Peawa (Comanche) of Fletcher, Mam Sookwat (Comanche) of Baird, and Apache Ben of Apache, Oklahoma.[8] A certificate of incorporation was granted to “The Native American Church” at Oklahoma City under the Great Seal and the signature of the Secretary of State, dated October 10, 1918, and signed by Alfred Wilson (Cheyenne), Louis McDonald (Ponca), Delos Lonewolf (Kiowa), Herman McCarthy (Osage) and Tennequah (Comanche). The strongly intertribal nature[9] of the organization is indicated by the various tribal affiliations of the men elected to the offices of the Native American Church. The constitution under which the charter was obtained was changed at Washington in the administration of Ned Brace, and several amendments were made in 1935. Frank Cayou (Omaha) of Hominy has for some time been seeking a national charter from Congress, through Secretary Ickes and Commissioner Collier, so far with no success. Formerly there was an annual tax of two dollars for each individual member of the state organization, one half kept by the local group and the other half sent to the state headquarters, but later this was changed to a ten dollar tax per tribe. In Oklahoma there are now (1936) twenty-four tribes organized in the church, and these send two delegates from each local church (if there are several locals there may be as many as six delegates from one tribe). The yearly convention is held the last Friday in November, formerly always in El Reno, though in 1936 it was held in Hominy. El Reno is the site of “The Wigwam,” a young Indian men’s fraternal organization which once maintained a museum-meeting room convenient for these conventions, hence the Native American Church was incorporated as of this place. Because of the many native languages represented, English is the lingua Franca of negotiations at conventions. The chief function of the state organization so far has been the mobilizing of political power and application of pressure on legislative groups, in the preservation of what the Indians regard as their constitutionally guaranteed right of religious freedom.
