The Southern Christian Leadership Conference (SCLC) is a civil rights organization founded in 1957, composed mainly of African American clergymen and their supporters, aimed at achieving civil rights through nonviolent protest and civil disobedience. The SCLC played a crucial role in the civil rights movement, advocating for racial equality and justice, and significantly influencing key legislation during the 1960s, particularly the Civil Rights Act of 1964 and the Voting Rights Act of 1965.
