In the civil rights movement of the mid-20th century, black Christian thought helped to undermine the white supremacist racial system that had governed America for centuries. The civil rights revolution in American history was, to a considerable degree, a religious revolution, one whose social and spiritual impact inspired numerous other movements around the world. Key to the work was a transformation of American religious thought and practice in ways that deftly combined the social gospel and black church traditions, infused with Gandhian notions of active resistance and “soul force,” as well as secular ideas of hardheaded political organizing and the kinds of legal maneuverings that led to the seminal court case of Brown v. Board of Education. The civil rights movement had legislative aims; it was, to that extent, a political movement. But it was also a religious movement, sustained by the religious power unlocked within southern black churches. The historically racist grounding of whiteness as dominant and blackness as inferior was radically overturned in part through a reimagination of the same Christian thought that was part of creating it in the first place. In similar ways, the Mexican-American farmworkers’ movement drew on the mystic Catholic spirituality of Cesar Chavez and brought to national consciousness the lives and aspirations of an oppressed agricultural proletariat that lacked the most elementary rights of American citizens. American civil rights movements drew from, and were in part inspired by, the ideas of Mahatma Gandhi and the Indian independence movement. Gandhi’s movement deeply influenced black Americans who visited India from the 1930s to the 1950s and who brought home with them a mixture of ideas and practices deriving from sources as diverse as Gandhi and the 19th-century American progenitor of nonviolent civil disobedience, Henry David Thoreau. American civil rights movements subsequently became a model for any number of freedom movements internationally, notably including the anti-apartheid struggle in South Africa. There, religious figures such as Desmond Tutu became international symbols. Also, the black American freedom struggle based in the American South moved protestors in places as diverse as Czechoslovakia under Soviet domination and Chinese students staring down tanks in Tiananmen Square in 1989. In the post–civil rights era, some suggested that America had moved into a “post-racial” era, despite the overwhelming statistics documenting racial inequality in American society. Thus, activists who have mined the connection between religion, civil rights, and social justice will have plenty of work to do in the future. The struggle continues through such contemporary venues as the #blacklivesmatter movement.
