The Greensboro Four were a group of four African American college students who played a pivotal role in the Civil Rights Movement. On February 1, 1960, Ezell Blair Jr. (now known as Jibreel Khazan), Franklin McCain, Joseph McNeil, and David Richmond, all students at North Carolina Agricultural and Technical State University in Greensboro, North Carolina, staged a sit-in at a segregated Woolworth's lunch counter.

The four young men sat down at the "whites only" lunch counter and politely asked to be served. When they were refused service due to their race, they remained seated in protest. Their peaceful sit-in sparked a wave of similar protests across the country, with students and activists organizing sit-ins at segregated lunch counters in cities across the South.

The Greensboro Four's actions helped to galvanize the Civil Rights Movement and brought national attention to the injustices of segregation and discrimination. Their courageous stand inspired many others to join the fight for equality, and they are remembered as heroes of the movement. The sit-ins at Woolworth's eventually led to the desegregation of the lunch counter and became a symbol of the power of nonviolent civil disobedience in the struggle for civil rights.
