Horn Chips was a yuwipi man who performed a yuwipi ceremony for doubtful white missionaries who wanted to “expose” Horn Chips as a fraud. The missionaries hoped that the attending Lakota would convert to Christianity if the missionaries could convince them that their traditional religious ceremonies were “hocus-pocus.” The missionaries’ efforts to convert these Lakota to Christianity is reflective of how many Native Americans are coerced or forced to assimilate to white culture. Horn Chips, however, proved the missionaries wrong and actually succeeded in converting Christian Lakota to the traditional Lakota religion.
