East Germany

East-Germany, also known as the German Democratic Republic (GDR), in German known as Deut­sche Demokratische Republik (DDR), is a former state in the former Eastern Bloc, that existed du­ring the Cold War from 1949 to 1990. It comprised the region of Germany that, after World War II, was occupied by the former Soviet Union (USSR), including East Berlin (but not West Berlin) [1]. East-Germany was officially recognised as a nation state by the United Nations, as late as 1973.


This section of the website deals with equipment that was developed, built and/or used in the former DDR. In most cases, the equipment was used by a department of the Mini­ste­ri­um für Staatssicherheit (MfS) – the repressive state security service – better known as the Stasi. Fol­lo­wing the fall of the Berlin Wall in 1989, East-Germany was reunited with West-Germany in 1990.

Geography
East Germany was a country in Central Europe, formed on 7 October 1949. It was the part of Germany that, after WWII, was in the Soviet-occupied zone (German: Sowjetische Besatzungszone - SBZ). As such, it became a statellite state of the Soviet Union (USSR). Regarded by the West as a comunist state, it described itself as a socialist workers' and peasants' state [1].

The official language in East Germany was German, although schools were teaching Russian as a second language. The country was 108,333 km2 in size and initially had 18,388,000 inhibitants (1950), but by the time of the reunification (1990), the population had shrunk to 16,111,000 [1].

In Eastern Europe, the period from 1989 to 1990 is generally described as Die Wende (the turn) or the pieceful revolution. Following the Fall of the Berlin Wall on 9 November 1989, East-Ger­ma­ny was reunified with West-Germany on 3 October 1990. The four powers that had occupied and controlled West-Germany since WWIIUSA, USSR, UK and France – renounced their rights over Germany, after which the united Germany became fully sovereign on 15 March 1991.
