Published in Nationalism and Ethnic Politics, vol. 10, no. 3, 2004, this article examines regional consociations as institutional designs that combine two elements of traditional conflict resolution approaches: territorial autonomy and consociational power-sharing. From a conflict resolution perspective there are three particularly interesting dimensions, namely the factors in relation to structure and agency that ma ke it possible for a regional consociation to be established; their institutional design; and the conditions that are conducive to their stability. My primary interest in this paper is in the institutional design of regional consociations, but I also make some observations on their origin and touch upon stability conditions in a comparative institutional study of South Tyrol, Northern Ireland and Brussels.
