By means of two case studies, this paper demonstrates how customary chiefs in Northeast Congo crafted their power position under colonial indirect rule. The first case discusses chiefs' role in anioto or leopard-men killings to secure their authority over people, land and resources whilst circumventing colonial control. The second case concerns nebeli, a collective therapy characterised by the distribution of a medicine or charm used to protect, heal and harm in Northeast Congo and South Sudan. These case studies show that indirect rule designed customary chieftaincy too one-sidedly, based on patrilineal succession and land rights. It tried to cut chiefs off from spiritual and coercive power bases such as anioto and nebeli, which were part of local political culture. While colonial authorities framed institutions such as anioto and nebeli as subversive, and expected government-appointed chiefs to renounce them, they were clandestinely used by chiefs to retain their grip on local society whilst fulfilling their state-imposed duties. However, these institutions were not simply used to resist or by-pass colonial control, but also to support it. These historical cases help to gain insight in contemporary chiefs and militia leaders' continued use of similar coercive, spiritual and remedial means to boast their power.
