Where did martin Luther king start sit ins?

Martin Luther King Jr. played a pivotal role in the sit-in movement that began in Greensboro, North Carolina, in 1960. The first organized sit-in took place at a Woolworth's lunch counter, where African American students peacefully protested racial segregation by sitting at the counter and requesting service. This action inspired similar protests across the country and became a significant part of the Civil Rights Movement. King's leadership and the tactics used during these sit-ins helped galvanize support for desegregation efforts.
