Both the Federal Republic of Germany (West Germany) and the German Democratic Republic (East Germany) were admitted to the UN on 18 September 1973. Through the accession of the East German federal states to the Federal Republic of Germany, effective from 3 October 1990, the territory of the German Democratic Republic became part of the Federal Republic of Germany, today simply known as ''Germany''. Consequently, the Federal Republic of Germany continued being a member of the UN while the German Democratic Republic ceased to exist.
