The Poor People's Campaign, or Poor People's March on Washington, was a 1968 effort to gain economic justice for poor people in the United States. It was organized by Martin Luther King Jr. and the Southern Christian Leadership Conference (SCLC), and carried out under the leadership of Ralph Abernathy in the wake of King's assassination in April 1968.
The campaign demanded economic and human rights for poor Americans of diverse backgrounds. After presenting an organized set of demands to Congress and executive agencies, participants set up a 3,000-person protest camp on the Washington Mall, where they stayed for six weeks in the spring of 1968.
The Poor People's Campaign was motivated by a desire for economic justice: the idea that all people should have what they need to live.
