Setting the course for reunification

The desolate situation in the GDR led to a stream of immigrants to the West after the fall of the Berlin Wall - until Chancellor Helmut Kohl promised the introduction of the Deutsche Mark in the GDR in February 1990. The CDU emerged victorious in the GDR elections to the People's Chamber in March. An economic reform was linked to the monetary union, the Treuhandanstalt implemented the privatisation or liquidation of previously "state-owned enterprises". In order to mitigate the consequences for the people, the adoption of the social security systems was also laid down in the State Treaty on Monetary, Economic and Social Union. In September, the Bundestag, Bundesrat and Volkskammer approved another treaty, the actual Unification Treaty. The prerequisites for unity were also the consent of the former victorious powers to the two plus four negotiations and the guarantee of Poland's western border. On 3 October 1990, the GDR finally joined the Federal Republic.
