Alliance 90 (German: Bündnis 90) was an alliance of three non-Communist political groups in East Germany. It merged with the German Green Party in 1993 to form Alliance '90/The Greens.
Bündnis 90 was formed in February 1990 by Neues Forum, Demokratie Jetzt and the Initiative Frieden und Menschenrechte. It received 2.9% of the vote in the 1990 Volkskammer elections. For the first all-German elections it formed a joint list with the East German Green Party. It was this coalition that merged with the West German Green Party in 1993.
On 7 February 1990, the Neue Forum (“New Forum”), the Initiative Frieden und Menschenrechte (“Peace and Human Rights Initiative”) and Demokratie Jetzt (“Democracy Now”) groups agreed upon the creation of the strategic partnership Bündnis 90 (“Alliance ’90”) for the German Volkskammer elections. On 18 March 1990, in the next and final free election of the former East Germany, the electoral alliance received 2.9% of the vote, thus securing 12 seats. By far the best result for Alliance ’90 was in constituency of Berlin with 6.3%. In the remaining constituencies results ranged from 1.6% in Neubrandenburg to 3.8% in Potsdam. Together with the eight electees from the “Green Party in the GDR”, they created the Fraktion Bündnis 90/Grüne (“Alliance ’90/Greens Party”).
In the East German Landtag election on 14 October 1990 the differently-comprised electoral alliances made their entry into every Landtag except Mecklenburg-Vorpommern, where the Neue Forum did not participate in the alliance. In Brandenburg, the three civic groups of the Bündnis 90 took office alone. In other states, the Greens also successfully took part in the electoral alliances. In Brandenburg from 1990 until 1994, Bündnis 90 formed part of a traffic light coalition with the Social Democrats and Free Democrats.
