It is commonplace to talk about the recurring crises in Europe, referring to the prevailing understanding that, since the ratification of the Maastricht Treaty, the European integration has become ‘constrained’ by dissensus, polarisation and controversies. In this seminar, the speakers will present their recent work published in an edited volume on the politicisation of the EU which provides an innovative and politically-aware approach to the phenomenon. The speakers will address both methodological insights advanced in the book and the policy-shaping effects of the politicisation discourse in the EU context.
