John Wilson, a Caddo- Delaware, also known as Moonhead, is credited with the birth of this religion around the year 1890. He was asked to build a Peyote altar to conduct Big Moon rituals for Tall Chief, the Quapaw chief. While Wilson was visiting Osage territory, an Osage man who had attended a Peyote meeting beforehand, had asked Wilson to share his new revelations about big moon peyotism and its rules with a group of Osage people. Wilson agreed and met with them. This religion was adopted by Witchita, Delaware, Quapaw, Shawnee, Oklahoma Seneca-Cayuga, but no tribe converted the Osage. The Osage are the only current practitioners in the religion to this day. The Chief of the Osage people, Black Dog, was left without a tribe because his was won over by the big moon peyotism worshippers.
