Martin Luther King Jr. joining in singing “We Shall Overcome” before he addressed the national convention of the Progressive National Baptist Convention in Cincinnati on Sept. 8, 1967. The 1.5 million-member Baptist group was founded in Cincinnati in 1961 by African-American church members seeking to create a religious movement that would support King’s civil rights advocacy.
