<human>:  I have a question about the Civil Rights Movement. What was the name of the first major sit-in at a lunch counter in the US?
<bot>: The first major sit-in at a lunch counter in the US was the Greensboro sit-in. It was held in North Carolina in 1960. The sit-in was organized by four African American students at North Carolina A&T State University. The students wanted to protest segregation at the lunch counter in the Woolworth’s store in Greensboro.
