The First Pan-African Conference is held in London on July 23–25, 1900 (just prior to the Paris Exhibition of 1900 "in order to allow tourists of African descent to attend both events").

Organized primarily by the Trinidadian barrister Henry Sylvester Williams, it takes place in Westminster Town Hall (now Caxton Hall) and is attended by thirty-seven delegates and about ten other participants and observers from Africa, the West Indies, the US and the UK, including Samuel Coleridge-Taylor (the youngest delegate), John Alcindor, Benito Sylvain, Dadabhai Naoroji, John Archer, Henry Francis Downing, and W. E. B. Du Bois, with Bishop Alexander Walters of the AME Zion Church taking the chair.

Du Bois plays a leading role, drafting a letter ("Address to the Nations of the World") to European leaders appealing to them to struggle against racism, to grant colonies in Africa and the West Indies the right to self-government and demanding political and other rights for African Americans.
