The Pentecostal Church of God was formed in Chicago, Illinois, in 1919 by a group of Pentecostal leaders. They chose Rev. John C. Sinclair as their first chairman and the Pentecostal Assemblies of the USA as their name. That name was changed to the Pentecostal Church of God in 1922. The church has enjoyed steady growth through the years and has moved its international headquarters to Ottumwa, Iowa in 1927, Kansas City, Missouri in 1933, and Joplin Missouri in 1951.
