The remarkable story of how Frederick Douglass went from condemning the Constitution as a proslavery pact to celebrating it as a “glorious liberty document” that promises freedom to everyone The speeches and writings of Frederick Douglass contain some of the most probing examinations ever of the role that slavery played in America’s founding. In Frederick Douglass’s American Founding , Dennis Rasmussen traces the great abolitionist’s intellectual journey from denouncing the founders as hypocrites and the Constitution as evil to embracing them both. Throughout the 1840s, Douglass described the founders as “little better than a band of pirates” and the Constitution as “a most cunningly-devised and wicked compact.” Beginning in 1849, however, he undertook a long period of study and reflection that produced a dramatic change of mind. From 1851 on, Douglass contended that the founders were resolutely opposed to slavery and that the Constitution was a “glorious liberty document” that required immediate emancipation, despite several clauses that appeared to suggest otherwise. Even after embracing the Constitution and the founders, Douglass remained second to none in castigating America for the evils of slavery. Indeed, as he argued in his greatest speech, “What to the Slave Is the Fourth of July?” (1852), the glory of the nation’s founding ideals only put their persistent betrayal into starker relief. Douglass also came to regard the founders as radicals in their fight against tyranny. That was why he insisted that he and his fellow abolitionists, rather than moderates like Abraham Lincoln, were the founders’ true heirs. Whatever you think about the founding, Douglass’s arguments will challenge—and perhaps even change—your views. After seeing the Constitution through Douglass’s eyes, it is difficult to look at it in the same way again.
