Issues and campaign
This was the first election conducted after German reunification which took place on 3 October. Almost 150 seats had been added to represent the newly re-established eastern states of Germany without reducing the number of Western members. The euphoria following the reunification gave the ruling CDU/CSU–FDP coalition a dramatic advantage in both Western and Eastern Germany throughout the campaign.
This was the one and only election for which the 5% threshold was not applied nationwide, but separately for East Germany (including East Berlin) and West Germany (including West Berlin). As a result, while the Western The Greens failed to gain representation, an ideologically similar party from the East, Alliance 90, did. They merged to form Alliance 90/The Greens in 1993.
