Legislative elections were held in East Germany on 18 March 1990. It was the first—and as it turned out, only—free parliamentary election in the GDR, and the first truly free election held in that part of Germany since 1933. A total of 400 deputies were elected to the Volkskammer.
On 20 September of the same year, the parliament voted to dissolve East Germany and to unify its territory with the Federal Republic of Germany, thus ending the state's 40-year existence. The unification treaty was approved on a 442–47 vote by the Bundestag and by a 299–80 margin in the Volkskammer, and took effect on 3 October.
