Button, Student Nonviolent Coordinating Committee, circa 1965

The Student Nonviolent Coordinating Committee (SNCC) was organized in 1960 after four black college students demanded service at a Woolworth's lunch counter. The organization worked with black communities throughout the South to support sit-ins and other non-violent direct actions protesting segregation, as well as register African-American voters. By the late 1960s, the organization had become more militant, often clashing with mainstream civil rights groups.
