Leaders of the civil rights movement had a multitude of strategies to consider. These included classic civil disobedience, education campaigns, coalition building, threats of violence, and urban riots. Looking back, each option can be evaluated in terms of its ethics and effectiveness. Non-violent means are certainly the most ethical, while violent means are frequently more effective in attaining movement goals in the short-term. In order to determine what should be done, peace needs to be the guiding principle. Therefore, leaders of an ideal movement need to exhaust all of the conservative approaches first, leaving civil disobedience as a last resort.
