An Arab revolt against German traders on the East African coast north of Zanzibar. The Arab leader Abushiri (Abu Bashir ibn Salim al‐Harthi) united local hostility to German colonization at Pangani when in August 1888 the Germans hauled down the Sultan of Zanzibar’s flag and hoisted their own. British and German interference in the slave, ivory, and rubber trades, and their conduct in mosques, had already caused resentment. Abushiri’s resistance spread inland to the Usambara mountains, and to Lake Victoria. The revolt was crushed by the German explorer and administrator Hermann von Wissmann in 1889.
