This article investigates how the positions, strategies and modes of interaction of the German Länder have changed over time in response to the process of Europeanization. By applying the method of process tracing within a theoretical framework of rational choice institutionalism, the article concentrates on the Länder's responses to (1) the transfer of policy competences to the European level and (2) the enlargement of the European polity. Thereby, the article sheds new light on the Europeanization of the German federal system. It is shown that the transfer of policy competences to the European level have had the greatest impact on the Länder, which have reacted increasingly strategically by successfully demanding more power in the national coordination mechanism. However, the European Union enlargements have also had an effect as together with the transfer of policy competences they have resulted in a more sceptical attitude of the Länder towards (the perceived ever expanding) European Union.
