This speech by Cardinal Lavigerie, the Archbishop of North Africa, head of the Catholic missionary organisation of 'White Fathers' and leader of the "European Crusade against the African Slave Trade" (3) was delivered in French at the Prince's Hall in London, in July 1888, and appears translated into English in this pamphlet. Lavigerie was engaged on a speaking tour of Europe, in an attempt to raise support for his "Crusade". An article from the Daily News notes the enthusiastic welcome for Lavigerie in London, and suggests that while "the spectacle of a French Cardinal on the platform of an English Anti-Slavery meeting must have seemed to them something strange" (4), it was indicative of increased religious tolerance and co-operation. Lavigerie's speech appealed to British nationalism by praising the work of Livingstone in Africa, and long-standing abolitionist zeal in Britain. He denounced the slave raids on African villages and showed the audience a wooden yoke used in the transportation of slaves, stressing the "sacred obligation" (9) of European colonialism in Africa to end this slave trade.
