This chapter examines a lesser-known area of interest for Sartori: the theory of dictatorship. Political science literature on this subject has mostly focused on totalitarian and authoritarian regimes, to which Sartori also devoted some attention. What he was most interested in, however, was a theory of dictatorship in general, where dictatorship is a class that encompasses the traditional concepts of totalitarianism and authoritarianism. Sartori developed two typologies of dictatorships. The first is based on four basic distinct criteria: intensity, objective, origin, and ideology. This results in up to ten types of dictatorship: simple, Caesarist, totalitarian, revolutionary, dictatorship of order, political, military, bureaucratic, non-ideological, and ideological. This broad typology, while highly original, is also somewhat convoluted and has not gained much traction (a role in this was also played, however, by the fact that it was not translated into English). Sartori, therefore, presented a much simpler typology of dictatorships in one of his later texts (in English), which was also more consistent with the more established typologies of other scholars: totalitarian, authoritarian, and simple.
