Book excerpt: Pentecost in Tulsa tells the story of how the city became an important epicenter of Pentecostal and Charismatic Christianity in the United States. In its earliest days, revivals led by such luminaires as Charles Parham, Aimee Semple McPherson, and Raymond T. Richey helped establish important Pentecostal churches. Later, well-known evangelists in the movement, such as Oral Roberts and Kenneth Hagin, launched worldwide ministries from Tulsa that impacted millions around the globe. This book also reveals the untold story of a resilient Black Pentecostal community that endured the 1921 Tulsa Race Massacre and revived the famous Greenwood District. Through these triumphs and tragedies, Tulsa has emerged as a significant location with continuing impact on the story of Pentecostalism.
