"In the first book to investigate in detail the origins of antislavery thought and rhetoric within the Society of Friends, Brycchan Carey shows how the Quakers turned against slavery in the first half of the eighteenth century and became the first organization to take a stand against the slave trade.Through meticulous examination of the earliest writings of the Friends, including journals and letters, Carey reveals the society's gradual transition from expressing doubt about slavery to adamant opposition.
