The Azusa Street Revival was a significant religious movement that began in 1906 in Los Angeles, California. It was led by William J. Seymour, an African American preacher, and became a pivotal event in the history of the Pentecostal movement. The revival emphasized the experience of speaking in tongues, healing, and a deep spiritual connection with God, attracting a diverse group of participants. The revival took place at a former church on Azusa Street and lasted for several years, drawing thousands of people from various backgrounds. It played a crucial role in spreading Pentecostalism across the United States and around the world, influencing many other Christian denominations and movements.
