Post by Skyler J. Collins (Editor). This episode features a lecture by historian Jim Powell from 2011. For thousands of years, slavery went unchallenged in principle. Then in a single century, slavery was abolished and more than seven million slaves were freed throughout the Western hemisphere. The scope and speed of this transformation make it one of the most amazing feats in modern history. Powell concisely illuminates the beginnings of the abolitionist movement, then proceeds through the processes, the battles, the final victory of emancipation, and the incredible impact of its aftermath. Ultimately, Powell argues, the more violence was involved in the emancipation process, the worse the outcomes were, making a provocative case for peaceful antislavery struggles.
