The Azusa Street Revival was a historic revival meeting that took place in Los Angeles, California, and is the origin of the Pentecostal movement. It was led by William J. Seymour, an African American preacher. It began with a meeting on April 9, 1906, and continued until roughly 1915. The revival was characterized by spiritual experiences accompanied with testimonies of physical healing miracles, worship services and speaking in tongues. The participants were criticized by the secular media and Christian theologians for behaviors considered to be outrageous and unorthodox, especially at the time. Today, the revival is considered by historians to be the primary catalyst for the spread of Pentecostalism in the 20th century.
In 1905, William J. Seymour, the one-eyed 34-year-old son of freed slaves, was a student of well-known Pentecostal preacher Charles Parham and an interim pastor for a small holiness church in Topeka, Kansas. Neely Terry, an African American woman who attended a small holiness church pastored by Julia Hutchins in Los Angeles, made a trip to visit family in Houston late in 1905. While in Houston, she visited Seymour's church, where he preached on receiving the Holy Spirit with the evidence of speaking in other tongues, and though he had not experienced this personally, Terry was impressed with his character and message. Once home in California, Terry suggested that Seymour be invited to speak at the local church. Seymour received and accepted the invitation in February 1906, and he received financial help and a blessing from Parham for his planned one-month visit.
