Integrating lunch counters in the Southern United States through the use of sit-in political protests in the 1960s was a major accomplishment of the civil rights movement. These involved African Americans and their supporters sitting at the lunch counter in areas designated for "whites only", insisting that they be served food and beverages. The Woolworth's lunch counter in Greensboro, North Carolina, was the site of one of the first such sit-ins in 1960. In recognition of its significance, part of the Greensboro lunch counter has been installed at the Smithsonian Institution's National Museum of American History, while the former Woolworth's building is now the site of International Civil Rights Center and Museum.
