Martin Luther King, Jr. Quote
The Emancipation Proclamation had four enduring results. First, it gave force to the executive power to change conditions in the national interest on a broad and far-reaching scale. Second, it dealt a devastating blow to the system of slaveholding and an economy built upon it, which had been muscular enough to engage in warfare on the Federal government. Third, it enabled the Negro to play a significant role in his own liberation with the ability to organize and to struggle, with less of the bestial retaliation his slave status had permitted to his masters. Fourth, it resurrected and restated the principle of equality upon which the founding of the nation rested.
