This chapter is concerned about the role of elites in autocratic regimes. It focuses mainly on business and military elites and asks how autocracies can bind these actors to their inner sanctum. It reviews previous decades of research, highlighting the recent institutionalist turn in comparative authoritarianism, but also traces back debates about neo-patrimonialism, clientelism, patronage, and corruption. The chapter introduces the conceptual distinction between co-optation in formalized arenas like political parties and parliaments as well as in the shadowland of informality. It argues that intra-elite cohesion can be secured via reactive and preventive measures as well as by absorbing new members (widening) or by interweaving interests and instilling a feeling of reciprocity (deepening) among the elite members. The chapter ends by explicating concrete operationalization advice for empirical research.
