This case-study of the ANC in South Africa is one of a series produced by participants in an ongoing Berghof research project on transitions from violence to peace. The project’s overall aim is to learn from the experience of those in resistance or liberation movements who have used violence in their struggle but have also engaged politically during the conflict and in any peace process. Recent experience around the world has demonstrated that reaching political settlement in protracted social conflict always eventually needs the involvement of such movements. Our aim here is to discover how, from a non-state perspective, such political development is handled, what is the relationship between political and military strategies and tactics, and to learn more about how such movements (often sweepingly and simplistically bundled under the label of non-state armed groups) contribute to the transformation of conflict and to peacemaking. We can then use that experiential knowledge (1) to offer support to other movements who might be considering such a shift of strategy, and (2) to help other actors (states and international) to understand more clearly how to engage meaningfully with such movements to bring about political progress and peaceful settlement.
