During the last decade, the concept of patrimonialism has become firmly embedded in political science and the sociological literature, being used primarily to explain the operation of bureaucracies in the underdeveloped world. This research note examines some of the usages of the term and attempts to assess its explanatory value. It is suggested that, as employed in much recent literature, “patrimonialism” has not contributed a great deal to the understanding of underdeveloped polities. The author argues that this is primarily because the literature has generally ignored the broader structural factors of which the phenomenon of patrimonialism is a manifestation. Taking account of these structural factors and locating patrimonialism within the broader context of underdevelopment will better equip us to understand the character and operation of Third World bureaucracies.
