The World Anti-Slavery Convention met for the first time at Exeter Hall in London, on 12–23 June 1840. It was organised by the British and Foreign Anti-Slavery Society, largely on the initiative of the English Quaker Joseph Sturge. The exclusion of women from the convention gave a great impetus to the women's suffrage movement in the United States.

Anti-Slavery International, founded as the British and Foreign Anti-Slavery Society in 1839, is an international non-governmental organisation, registered charity and advocacy group, based in the United Kingdom. It is the world's oldest international human rights organisation, and works exclusively against slavery and related abuses.
