File - This Aug. 31, 1990 file photo shows the last page of the German unification treaty as it was signed in East Berlin, Germany. It bears the signatures of West German Interior Minister Wolfgang Schaeuble and of East German chief negotiator Guenther Krause plus the seals of West and East Germany. Germany was divided into communist East Germany and capitalist West Germany following the defeat of the Nazis in World War II. The eastern German Democratic Republic formally joined the western Federal Republic of Germany on Oct. 3, 1990, after months of peaceful protests had brought down the ailing communist system in the East.
