Functional theory of state is one of the most important Theories in the study of state, but literature on Comparative typology of political regimes has ignored this theory. Instead, the author in this paper by using of the functional theory of state tries to offer a functional typology of political regimes. Paper in its distinctive typology, identifies Rentier regime, Welfare regime and Populist regime that emphasis on distributive and Redistributive function more than other regimes, so that we call all of them distributive and Redistributive regimes. Since the comparative method requires attention to similarities and differences, the paper emphasizes on functional similarity of these regimes on the one hand, and some their differences on the other hand. Finally, paper concludes that despite this functional similarity, these political regimes have so many different characteristics which partly related to this similar function.
