Students and seminarians in both the South and the North played key roles in every phase of the movement. Church and student-led movements, such as the Nashville Student Movement, developed their own organizational and sustaining structures. The Southern Christian Leadership Conference (SCLC), founded in 1957, coordinated and raised funds, mostly from northern sources, for local protests and for the training of black leaders. The Student Nonviolent Coordinating Committee, or SNCC, founded in 1957, developed the "jail-no-bail" strategy. SNCC's role was to develop and link sit-in campaigns and to help organize freedom rides, voter registration drives, and other protest activities. These three new groups often joined forces with existing organizations such as the National Association for the Advancement of Colored People (NAACP), founded in 1909, the Congress of Racial Equality (CORE), founded in 1942, and the National Urban League. The NAACP and its Director, Roy Wilkins, provided legal counsel for jailed demonstrators, helped raise bail, and continued to test segregation and discrimination in the courts as it had been doing for half a century. CORE initiated the 1961 Freedom Rides which involved many SNCC members, and CORE's leader James Farmer later became executive secretary of SNCC.
