After the Second World War ended, Germany was divided into what became eventually a Western Zone and an Eastern Zone. By 1949, Germany had a parliamentary democracy in the West, called the Federal Republic of Germany (FRG, commonly "West Germany"), and a communist state in the East, called the German Democratic Republic (GDR, commonly "East Germany"). Opportunities to reunify both halves appeared unlikely from the Western standpoint. The Socialist Unity Party of Germany feared losing power if free elections were held. Germany had still not signed a peace treaty for the war because of the animosity of the three Western Powers towards the Soviet Union. The peace treaty with Germany, the Two Plus Four Agreement, was signed only in 1990.
