From the author of the widely acclaimed King Leopold's Ghost comes the taut, gripping account of one of the most brilliantly organized social justice campaigns in history-the fight to free the slaves of the British Empire. In early 1787, twelve men-a printer, a lawyer, a clergyman, and others united by their hatred of slavery-came together in a London printing shop and began a remarkable grass-roots movement, battling for the rights of people on another continent. Masterfully stoking public opinion, the movement's leaders pioneered a variety of techniques that have been adopted by citizens' movements ever since, from consumer boycotts to wall posters and lapel buttons to celebrity endorsements. A deft chronicle of this groundbreaking antislavery crusade and its powerful enemies, Bury the Chains gives a little-celebrated human rights watershed its due at last.
