"The early and more moderate American antislavery societies were called "abolition" societies, and the later and more militant groups were "antislavery" societies. British reformers, too, were by no means consistent in distinguishing the slave trade from slavery. In England, "the abolition" always referred to the end of the slave trade; but many "abolitionists" favored emancipation, and "emancipationists" were also known as "abolitionists." The term "anti-slavist," used by Jeremy Bentham, never gained wide currency. For both British and American reformers, "abolitionism" and "antislavery" were often interchangeable terms."
