Congo Arab war: The Congo Arab war (also known as the Congolese-Arab war and the Belgo-Arab War) took place in what is now the Democratic Republic of the Congo between the forces of Belgian King Leopold II's Congo Free State and various Zanzibari "Arab" slave traders led by Sefu bin Hamid, the son of Tippu Tip.  Fighting occurred in the eastern Congo between 1892 and 1894.  It was a proxy war, with most of the fighting being done by native Congolese, who aligned themselves with either side and sometimes switched sides.  The causes of the war were mainly economic, since Leopold and the Arabs were contending to gain control of the wealth of the Congo.  The war ended in January 1894 with a victory of Leopold's forces.  Initially King Leopold II collaborated with the Arabs but competition over the control of ivory and Leopold II's humanitarian pledges to the Berlin Conference to end slavery, turned his stance to confrontational.  The war against the Swahili-Arab economic and political power was presented as a Christian anti-slavery crusade.
