A project concerning itself with the effects of the past on the European integration process must also raise the question of the emergence of guiding historical images in the course of this process. As the past is not objective truth, but a perception generated by various actors (e.g., politicians, populist movements) as well as by history as a science in accordance with its own aims and rationality criteria, it appears in very different narratives. Many such historical images of Europe are generated by legal history. Since the Treaty on the European Union brought European integration a deeper, political dimension, a euphoria about Europe has broken out in legal history.
