The aim of this study is to demonstrate the validity of the thesis that in Indonesia one can find institutions that characterize two power-sharing models which are considered opposites of one another in political theory – centripetalism and consociationalism. In consequence, the Indonesian power-sharing system should be viewed as a hybrid, or mixed, system, and not a typically centripetal system as is usually the case in the literature. At the beginning of this article, a short analysis of Indonesia's political situation is given for the purpose of defining the factors which determined the introduction of inter-segmental power-sharing solutions in that country. This is followed by a description of the specificity of consociationalism and centripetalism. The article goes on to discuss specific institutions of both power-sharing models which exist in Indonesia and ends with some concluding remarks on the thesis advanced at the outset.
