EU institutions have frequently been reformed since the origins of what is now the European Union (EU), and particularly so over the past twenty years. This chapter explains why and how this quasi-constant change has taken place. It begins by identifying five phases in this history: the founding, consolidation, relaunch, adaptation, and the current phase of reaction to functional challenges. The chapter then assesses the respective weight of state interests, ideas, and institutions in the evolution of EU institutions. In retrospect, institutional change in the EU appears to have followed a functionalist logic, leading to complex compromises that, in turn, prompt regular calls for ‘simplification’ and democratization.
