World Anti-Slavery Convention

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 had important ramifications for the women's suffrage movement in the United States.

The Society for the Abolition of the Slave Trade was principally a Quaker society founded in the eighteenth century by Thomas Clarkson. The slave trade had been abolished throughout the British Empire in 1807. In August 1833 the British government passed the Slavery Abolition Act, advocated by William Wilberforce, which abolished slavery in the British Empire from August 1834, when some 800,000 people in the British empire became free.

Given the perceived need for a society to campaign for anti-slavery worldwide, the British and Foreign Anti-Slavery Society (BFASS) was accordingly founded in 1839. One of its first significant deeds was to organize the World Anti-Slavery Convention in 1840: "Our expectations, we confess, were high, and the reality did not disappoint them." The preparations for this event had begun in 1839, when the Society circulated an advertisement inviting delegates to participate in the convention. Over 200 of the official delegates were British. The next largest group was the Americans, with around 50 delegates. Only small numbers of delegates from other nations attended.

The circular message, distributed in 1839 provoked a controversial response from American opponents of slavery. The Garrisonian faction supported the participation of women in the anti-slavery movement. They were opposed by the supporters of Lewis Tappan. When the latter group sent a message to the BFASS opposing the inclusion of women, a second circular was issued in February 1840 which explicitly stated that the meeting was limited to "gentlemen".
