SNCC
The Student Non-Violent Coordinating Committee (SNCC; pronounced "Snick") was a Marxist-Leninist group founded in the early 1960s.
It is most famous for staging "sit-ins" in restaurants across the American South, where black protestors (and a number of white supporters) sat in the "Whites Only" section of a segregated restaurant, and sat there and sat there, even when the waiters refused service to them.
In the late 1960s, a radical antisemitic black supremacist named Stokely Carmichael took over SNCC and started advocating violence and black nationalism. He was a racist who fired all the white members of SNCC. Later, another black nationalist and member of the Nation of Islam, H. Rap Brown, changed the name of SNCC to Student National Coordinance Committee, reflecting the organization's suport of violence. The now-weakened SNCC utimately crumbled in the early 1970s.
