Parham received this same experience sometime later and began preaching it in all his services. Parham believed this was xenoglossia and that missionaries would no longer need to study foreign languages. After 1901, Parham closed his Topeka school and began a four-year revival tour throughout Kansas and Missouri. He taught that the baptism with the Holy Spirit was a third experience, subsequent to conversion and sanctification. Sanctification cleansed the believer, but Spirit baptism empowered for service. At about the same time that Parham was spreading his doctrine of initial evidence in the Midwestern United States, news of the Welsh Revival of 1904–05 ignited intense speculation among radical evangelicals around the world and particularly in the US of a coming move of the Spirit which would renew the entire Christian Church. This revival saw thousands of conversions and also exhibited speaking in tongues. In 1905, Parham moved to Houston, Texas, where he started a Bible training school. One of his students was William J. Seymour, a one-eyed black preacher. Seymour traveled to Los Angeles where his preaching sparked the three-year-long Azusa Street Revival in 1906. The revival first broke out on Monday April 9, 1906 at 214 Bonnie Brae Street and then moved to 312 Azusa Street on Friday, April 14, 1906. Worship at the racially integrated Azusa Mission featured an absence of any order of service. People preached and testified as moved by the Spirit, spoke and sung in tongues, and fell in the Spirit. The revival attracted both religious and secular media attention, and thousands of visitors flocked to the mission, carrying the "fire" back to their home churches. Despite the work of various Wesleyan groups such as Parham's and D. L. Moody's revivals, the beginning of the widespread Pentecostal movement in the US is generally considered to have begun with Seymour's Azusa Street Revival. The crowds of African-Americans and whites worshiping together at William Seymour's Azusa Street Mission set the tone for much of the early Pentecostal movement. During the period of 1906–24, Pentecostals defied social, cultural and political norms of the time that called for racial segregation and the enactment of Jim Crow laws. The Church of God in Christ, the Church of God (Cleveland), the Pentecostal Holiness Church, and the Pentecostal Assemblies of the World were all interracial denominations before the 1920s. These groups, especially in the Jim Crow South were under great pressure to conform to segregation.
