The Poor People’s Campaign was the brainchild of Rev. Martin Luther King Jr. and SCLC, which was then led by Ralph Abernathy after King was slain in April. On June 19, 1968, campaign leadership declared the day “Solidarity Day” as a final rallying cry for protesters who gathered in “Resurrection City” on the grounds of the National Mall in Washington, D.C. The campaign and the city began establishing itself in May that year, which had the ultimate goal of calling attention to economic imbalance present in the nation. With the civil rights movement shifting in tone and many landmark rulings achieved, King felt the next necessary step was economic justice.
