Co-edited with by Oya Dursun-Ozkanca, this special issue was published by Civil Wars. It offers macro-framework for the study of regional and international regulation of intra-state conflict and is informed by two fundamental premises: (1) conflicts, while complex political phenomena, can be managed, prevented and settled; and (2) it is possible to understand different regulation processes and discover certain regularities in them that can help us understand the broader notion of conflict regulation and the role of regional and international organisations within it.
