This book examines the EU policy of the German Social Democrats (SPD) after German unification, following their rise to power in 1998 and their record in office under Chancellor Schröder. The study deals with policy formation in the SPD through an analysis of the opportunity structures for policy-making in the EU, Germany and the party itself. Across this time period, the SPD recalibrated its European policy to absorb the impact of German unification, deeper European integration and globalization, seeking to interpret a changing world.
