The National Baptist Convention USA (NBC), founded at Friendship Baptist Church of Atlanta in 1895, is the largest black religious organization in the U.S. Rev. A. D. Williams, the maternal grandfather of Martin Luther King Jr., attended the founding meeting. In 1954, Dr. King addressed the NBC’s Women’s Convention, speaking on Vision of a World Made New. Daddy King served on the convention’s board of directors. In 1953, Rev. Joseph H. Jackson was elected president of the NBC, a position he held until 1982. In 1960, King publicly disagreed with Jackson’s conservative stance on civil disobedience. At the 1961 convention, King and others supported Rev. Gardner C. Taylor instead of Jackson, which ended in a contentious election and legal battle in Jackson’s favor. L. V. Booth, Taylor and others including King and his family led the formation of a new convention, the Progressive National Baptist Convention.
