This paper casts a long view by investigating how the leaderships of the French Socialist and German Social Democratic parties perceived of and presented these four figures to the public from 1958 to the 1980s. It demonstrates how these parties’ mobilized, invoked, and/or downplayed these figures and their accomplishments. The paper then uses these findings as a window into the parties’ understanding of their own role in the European integration process and the direction it should take in the future. Did commemoration intersect with the mobilization of the memory of these figures for contemporary political struggles during the period of the Fouchet Plan and Empty Chair Crisis of the 1960s, and the negotiations and ratification processes of the Maastricht Treaty and the European Constitution? This will allow an assessment of the degree to which these “founding fathers” have become objects of cross-party consensus or are contested by Socialists in a manner that calls into question contemporary models of European integration.
