The Greensboro Four were four African American college students who staged a sit-in at a segregated Woolworth's lunch counter in Greensboro, North Carolina, on February 1, 1960. The four students were Ezell Blair Jr. (later known as Jibreel Khazan), Franklin McCain, Joseph McNeil, and David Richmond, all of whom were students at North Carolina Agricultural and Technical State University.

The sit-in at the Woolworth's lunch counter was a form of non-violent protest against racial segregation and discrimination. Despite being refused service, the four students remained seated at the lunch counter in peaceful protest, sparking a wave of sit-ins and protests across the South and leading to the desegregation of many establishments.

The Greensboro Four's courageous actions and the subsequent spread of sit-ins became a pivotal moment in the Civil Rights Movement, highlighting the power of nonviolent protest and the determination of young African Americans to fight for their rights and equality. Their actions inspired and mobilized many others in the struggle for civil rights and helped to bring about significant changes in American society.
