At the beginning of 1990, the desire to reunify both German states – the Federal Republic of Germany (FRG) and the German Democratic Republic (GDR) – was certainly present in the hearts and minds of many Germans, and this did not only mean those who had to function under the privations and restrictions of the Communist system of Eastern Germany. A symbol of those desires was the slogan which appeared on banners of the protesters in the GDR as early as in November 1989 - ”Wir sind ein Volk!” (German: We are one nation).
The road to the reunification of the two German states was complicated, however, and required not so much popular support, as consent of those countries which were responsible for the post-war fate of Germany in 1945 - the USA, England and France and also the Soviet Union.
Finally the reunification of the German states took place on 3 October 1990. You can read how this process developed from the perspective of the German Democratic Republic in the following text.
