1929 – 1968
Martin Luther King Jr. (1929–1968) was an American Baptist minister, theologian, and civil rights leader whose thought synthesized the Social Gospel tradition, Boston Personalism, and Gandhian nonviolence into a comprehensive philosophy of justice. Drawing on Reinhold Niebuhr, Walter Rauschenbusch, and the Sermon on the Mount, he articulated a political theology centered on the dignity of persons, the moral arc of history, and the redemptive power of unearned suffering. His arguments extended beyond domestic civil rights to address global poverty, militarism, and the structural conditions required for genuine democratic participation.
