The Chicago Freedom Movement’s organizing effort on the West Side focused on the rundown apartment buildings managed by Condor and Costalis as examples of the exploitation of inner-city residents. More than ten thousand persons attended a Freedom Festival at the International Amphitheater which featured a speech by Martin Luther King, Jr., and performances by Harry Belafonte, Mahalia Jackson, and Dick Gregory. King called for a “grand alliance of the forces of good will with the underprivileged to end the dark days of powerless existence.”
