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 arrangements 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 that exist in Indonesia and ends with some concluding remarks on the thesis advanced at the outset. The article has been published in "Polish Political Science Yearbook" 2017, vol. 46, no. 1, pp. 168–185.
