On 31 March 1893, the IBEAC formally ended its involvement in Uganda. Missionaries, led by Alfred Tucker, lobbied the British government to take over the administration of Uganda in place of the IBEAC, arguing that British withdrawal would lead to a continuance of the civil war between the different religious factions. Shortly after, Sir Gerald Portal, a representative of the British government on the ground in Uganda, proposed a plan of double chieftainships - whereby every chieftainship would have one Protestant and one Catholic chief. On 19 April 1893, the British government and the chiefs of Uganda signed a treaty giving effect to this plan.
