Focusing on the services and the cabinets, this chapter analyses the European Commission as a complex organizational, political, and social institution. Organizationally, it describes the Commission as a unique international bureaucracy which puts its French administrative tradition, consensus-based, and law-heavy internal procedures under the growing influence of an Anglo-American style of management. Politically, the chapter shows that the Commission increasingly behaves like a political executive that seeks to establish its own legitimacy vis-à-vis public opinion and member states by addressing partisan dynamics in the European Parliament. In terms of social relations, the chapter draws from the author’s ethnographic work to explore the transnational life of Commission civil servants and cabinet staffers who have made the Berlaymont their home.
