After achieving significant progress in the fight for civil rights, Martin Luther King, Jr. shifted his focus to economic justice and international peace in the years between 1965 and 1968. He led several campaigns in Chicago, Illinois, to highlight the issue of economic inequality, and he spoke out strongly against the Vietnam War. His work in these years culminated in the Poor People's Campaign, a broad effort to assemble a multiracial coalition of impoverished Americans who would advocate for economic change.
