Which group organized sitins?

The sit-ins during the Civil Rights Movement were primarily organized by young activists, particularly members of the Student Nonviolent Coordinating Committee (SNCC). These protests began in the early 1960s, with the most notable sit-in occurring at a Woolworth's lunch counter in Greensboro, North Carolina, in 1960. The movement aimed to challenge and dismantle racial segregation in public spaces. Other groups, including the NAACP and various college student organizations, also supported and participated in these efforts.
