The (De‐)Europeanization of the Political Class in the European Parliament: A Longitudinal Analysis of Members of the European Parliament's Career Patterns (1979–2019)

Abstract This article presents a systematic empirical analysis of the career patterns of all 3634 members of the European Parliament (MEPs) who served in the European Parliament (EP) over the last 40 years (1979–2019). It explains how changes in the EP's structure of opportunities have shaped the development of MEPs' career patterns. First, we show that the development of a European political class is not a recent trend but that this process took place in the early days of the EP (as soon as in the 1984–1989 term), albeit with variance across political groups of the European Parliament (EPGs) and Member States. Second, we observe that the transformation of party systems and electoral volatility have been questioning the existence of the European political class. Overall, we conclude that legislative institutions are only as strong as the individuals who are called to serve them. Recent rises in the EP's turnover could ultimately undermine the EP's formal policy‐making capacity in the middle and long terms.
