The Greensboro Four refers to a group of 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 students, Franklin McCain, Joseph McNeil, Ezell Blair Jr. (now Jibreel Khazan), and David Richmond, were all attending North Carolina Agricultural and Technical State University at the time.

Their act of peaceful protest sparked a wave of sit-ins and other nonviolent demonstrations against segregation and discrimination in public places throughout the South. The sit-in at the Woolworth's lunch counter lasted for six months, during which time the students faced verbal and physical harassment but remained committed to their cause.

The Greensboro Four's actions played a significant role in the civil rights movement and helped to desegregate lunch counters and other public spaces across the country. Their bravery and determination have been celebrated as a turning point in the struggle for racial equality in the United States.
