The moment
From April 1906 William J. Seymour, a Black Holiness preacher, led services in a run-down building on Azusa Street in Los Angeles where Black, white and Latino worshippers spoke in tongues, and visitors carried the practice across America and overseas. It was not the only source: Seymour's teacher Charles Parham had taught tongues-speaking as the sign of Spirit baptism at Topeka, Kansas, since 1901, and revivals in Wales (1904–05), at Pandita Ramabai's Mukti Mission in India (1905) and in Pyongyang (1907) fed a movement that historians now see as having several beginnings.
