The term 'Eurocracy' is a word that exists in all European languages. Yet beyond fantasized representations of the 'Brussels bubble', we know little about members of the European Parliament, Commissioners, European civil servants, lobbyists, members of the Governing Council of the European Central Bank, European trade unionists, diplomats and journalists who work in or around the EU institutions? What are their social and professional trajectories, the type of authority they possess, and how does it matter? Based on extensive fieldwork, this volume aims at answering these questions by building upon Pierre Bourdieu's theory of the field of bureaucracy. 45 years after Altiero Spinelli's 'The Eurocrats', this book sheds new light on the relational structures that underpin the functioning of the EU polity. Specialists of European affairs, scholars and students in politics, administration and sociology as well as citizens will find original insights to understanding EU institutions and why the European project appears to be in crisis.
