Notes the success of the 1960 Nashville Student Sit-In Movement in desegregating the city’s downtown lunch counters was an important event in both the history of the US Civil Rights movement and in the diffusion and progression of nonviolent action nationally and internationally. Shows that Nashville is a useful case for teaching strategic nonviolent action at the university level because of its short duration, its relatively clear stages, its emphasis on training and discipline, and the integral role played by students.
