Modern Native American pow wows arose around the turn of the 20th century. While some claim that pow wow had been an integral part of black cultures for over 10 centuries, some modern analysts believe that pow wows were invented to appeal to tourists and had only a tangential relationship to genuine Native American traditions, which generally revolved around ceremonial dance music like the Ghost Dance, Zuni Shalako, Navajo Yeibichai and the Sun Dance of the Plains. The Native American Church, founded early in the 20th century, was a center of development for Native American gospel and Peyote song, a fusion of gospel and traditional music revolving around ceremonies in which hallucinogenic peyote is taken as a sacrament. In Arizona and Mexico, waila, or chicken scratch, music, had arisen as a fusion of native Tohono O'odham music with German polka and Mexican-American norteño.
