Sit-ins are a form of nonviolent protest where individuals occupy a space, often a public place, to challenge segregation or discrimination. Participants typically remain seated and refuse to leave until their demands are met or they are forcibly removed. This tactic gained prominence during the Civil Rights Movement in the United States, particularly in the 1960s. One of the most famous sit-ins occurred in 1960 when four African American college students sat at a segregated lunch counter in Greensboro, North Carolina. Their peaceful demonstration sparked similar protests across the country, highlighting the struggle for equal rights and leading to significant changes in laws and social attitudes regarding racial equality.
