Also known as the Society for the Mitigation and Gradual Abolition of Slavery Throughout the British Dominions and, later, the London Anti-Slavery Society, the Anti-Slavery Society was founded with the purpose of advocating for the eradication of slavery in the British Empire. Following the passage of the Slavery Abolition Act of 1833, a new organization, the British and Foreign Anti-Slavery Society was formed in its place, shifting the focus to abolition on a global scale.
