The power of religion in the civil rights movement In a provocative assessment of the success of the civil rights movement, David L. Chappell reconsiders the intellectual roots of civil rights reform, showing how the prophetic tradition of the Old Testament - sometimes translated into secular language - drove African American activists to unprecedented solidarity and self-sacrifice. Martin Luther King Jr., Fannie Lou Hamer, James Lawson, Modjeska Simkins, and other black leaders believed, as the Hebrew prophets believed, that they had to stand apart from society and instigate dramatic changes to force an unwilling world to abandon its sinful ways. Although segregationists outvoted and outgunned black integrationists, the segregationists lost, Chappell concludes, largely because they did not have a religious commitment to their cause.
