This article reflects on the reasons why clientelism has reached its status as a determining category in the scholarly interpretation of the Italian political system. By returning to the earliest formulations of the concept (in the controversies of the late nineteenth century on the widening of suffrage) and then its successive recreations up to the political crisis of the 1990s (as a typical manifestation of the political ‘anomalies’ of an ‘incomplete’ democracy), it relates this centrality to the uses made of the denunciation of clientelism in political and institutional struggles and the way political science has developed in Italy as an academic discipline.
