In the early morning hours of June 23, 1968, thick clouds of tear gas rolled through a multitude of shacks on the National Mall. This shantytown was Resurrection City, and its residents were the nation’s poor. As many ran from their shelters, they saw Martin Luther King, Jr.’s final dream of economic equality withering in the gas. They had been citizens of the city for six weeks, all the while campaigning for rights for the poor around D.C. Now their work seemed all for naught. After an increase in violence and with an expiring living permit, the police had come to chase them out. Children were crying, adults screaming, and some were even vomiting. But amid the chaos, a song rang out: “we shall overcome.”
