A mutiny by Nubian mercenary troops in 1897 was only barely suppressed after two years of fighting, during which Baganda Christian allies of the British once again demonstrated their support for the colonial power. As a reward for this support, and in recognition of Buganda's formidable military presence, the British negotiated a separate treaty with Buganda, granting it a large measure of autonomy and self-government within the larger protectorate under indirect rule. One-half of Bunyoro's conquered territory was awarded to Buganda as well, including the historic heartland of the kingdom containing several Nyoro (Bunyoro) royal tombs. Buganda doubled in size from ten to twenty counties (), but the "lost counties" of Bunyoro remained a continuing grievance that would return to haunt Buganda in the 1960s.
