Background
- By the eighteenth century, moral and religious opposition to slavery began to challenge the economic and political systems that sustained it.
- Early critics of slavery emphasized the contradiction between Enlightenment ideals of liberty and the ongoing exploitation of millions of Africans.
- What began as a small religious protest evolved into a broad, organized movement that reshaped British and transatlantic attitudes toward human rights.

Religious and Moral Origins
The Role of the Quakers
- The Society of Friends (Quakers) were the first religious group to formally condemn slavery.
- By the 1750s, Quaker meetings in Britain and North America banned members from owning enslaved people.
- Leaders such as John Woolman and Anthony Benezet published pamphlets arguing that slavery violated Christian teachings of equality and peace.
- Quakers laid the foundation for a wider abolitionist movement rooted in conscience and faith.
Abolitionism
The political and moral movement dedicated to ending the slave trade and the institution of slavery itself.
Moral and Enlightenment Influence
- The rise of humanitarian thought and Enlightenment philosophy encouraged new ideas about universal rights and liberty.
- Activists argued that slavery contradicted both Christian ethics and natural law.
- These ideas helped turn moral conviction into political activism.
Humanitarianism
A belief in promoting human welfare and dignity; during the eighteenth century, it became a guiding principle for reformers opposing cruelty and injustice.
Expansion of the Abolition Movement
Early British Abolitionists
- Figures such as Granville Sharp and Thomas Clarkson investigated and publicized the abuses of the slave trade.
