Today, the 1989 Revolution in East Germany is recognized and celebrated as the event that abolished the German Democratic Republic (GDR) and brought about German unification. What is mostly overlooked, however, is that these are not the Revolution's only and, from the perspective of constitutional law, not even its most important achievements. More important with respect to understanding constitutional lawmaking in Germany is that the 1989 Revolution did not lead to an unconditional adoption of West German constitutional law in the new East German states. Instead, the Revolution had its own constitutional agenda, which went beyond the West German Basic Law and was transferred to unified Germany where it then needed to be integrated into the existing West German constitutional order. The Article reinterprets the 1989 Revolution and shows how a revolutionary popular movement in the GDR developed its own constitutional agenda, which first found legal manifestation in GDR legislation, and then was transferred to unified Germany through the Unification Treaty and the new state constitutions.
