After several weeks of tough negotiations on the “Treaty on the Establishment of German Unification,” an agreement was finally reached in the early morning hours of August 31, 1990. After the cabinets of both governments had approved the treaty, the two negotiators, Federal Minister of the Interior Wolfgang Schäuble (left) and East German Secretary of State Günther Krause (right), signed the Unification Treaty in East Berlin’s Kronprinzenpalais that very same day. This sealed the reunification of the German Democratic Republic and the Federal Republic of Germany on October 3, 1990.
