ABSTRACT There is a growing awareness that truth commissions (TCs) often leave victim and ex-combatant participants aggrieved. This is problematic since it can undermine support for peace processes. When attempting to explain such shortcomings, previous research has not paid sufficient attention to the patrimonial sources of TC-participants’ frustration. We argue that such forms of disenchantment are largely caused by internationalised TCs’ patrimonial mode of working, utilising tactics such as motorcades as manifestations of power and brokers to mobilise witnesses. To highlight the relevance of our argument, we use the work of the Sierra Leone Truth and Reconciliation Commission as an example.
