The Wesleyan movmnt was pretty big...they frowned on the trade..

John Wesley, a prominent Anglican cleric and theologian, was a vocal opponent of slavery. He published "Thoughts Upon Slavery" in 1774, where he condemned the practice as unjust and contrary to Christian principles, urging slave traders and owners to repent and free their slaves.

Wesley's stance on slavery influenced figures like William Wilberforce, who continued the fight against slavery after Wesley's death in 1791.

Wesley's writings and advocacy played a significant role in the abolitionist movement, contributing to the eventual passage of the Slavery Abolition Act in 1833.
