France and Germany played a highly visible leadership role during the management of the Euro crisis and the efforts to design a reform governance framework for the Euro area. This article provides a conceptualization of this bilateral leadership, which is then applied to trace the process of Franco-German leadership during the ongoing crisis of the Euro area. Franco-German leadership grew ever more important as the crisis deepened. After the French presidential election of 2012, however, the divergences between the two core states of the Euro area deepened and made the exercise of joint leadership more difficult to achieve. I consider this leadership role to be based on a compromise by proxy logic in which France and Germany, starting from divergent positions, strike bilateral compromises acceptable to other member states that feel their own interests are represented by either France or Germany. Their common capacity to find suitable remedies to cope with crisis, however, is not beyond doubt. The Franco-German approach followed an additive logic, combining the temporary and permanent financial support schemes-a French preference-with a concomitant strengthening of fiscal rules advocated by Germany. In the end, the two governments did not develop a common comprehensive strategy based on a shared conceptual framework.
