After the successful voting rights march in Alabama, King was unable to garner similar support for his effort to confront the problems of northern urban blacks. Early in 1966 he, together with local activist Al Raby, launched a major campaign against poverty and other urban problems and moved his family into an apartment in Chicago’s black ghetto. As King shifted the focus of his activities to the North, however, he discovered that the tactics used in the South were not as effective in Chicago.
King’s influence was tempered by the increasingly caustic tone of black militancy of the period after 1965. Black radicals increasingly turned away from the Gandhian precepts of King toward the Black Nationalism of Malcolm X, whose posthumously published autobiography and speeches reached large audiences after his assassination in February 1965. King refused to abandon his firmly rooted beliefs about racial integration and nonviolence.
In his last book, Where Do We Go from Here: Chaos or Community?, King dismissed the claim of Black Power advocates “to be the most revolutionary wing of the social revolution taking place in the United States,” but he acknowledged that they responded to a psychological need among African Americans he had not previously addressed. “Psychological freedom, a firm sense of self-esteem, is the most powerful weapon against the long night of physical slavery,” King wrote. “The Negro will only be free when he reaches down to the inner depths of his own being and signs with the pen and ink of assertive manhood his own emancipation proclamation”.
Indeed, even as his popularity declined, King spoke out strongly against American involvement in the Vietnam War, making his position public in an address, “Beyond Vietnam,” on 4 April 1967 at New York’s Riverside Church. King’s involvement in the anti-war movement reduced his ability to influence national racial policies and made him a target of further FBI investigations. Nevertheless, he became ever more insistent that his version of Gandhian nonviolence and social gospel Christianity was the most appropriate response to the problems of black Americans.
In December 1967 King announced the formation of the Poor People’s Campaign, designed to prod the federal government to strengthen its antipoverty efforts. King and other SCLC workers began to recruit poor people and antipoverty activists to come to Washington, D.C., to lobby on behalf of improved antipoverty programs. This effort was in its early stages when King became involved in the Memphis sanitation workers’ strike in Tennessee. On 28 March 1968, as King led thousands of sanitation workers and sympathizers on a march through downtown Memphis, black youngsters began throwing rocks and looting stores. This outbreak of violence led to extensive press criticisms of King’s entire antipoverty strategy.
