Green Party faction (Bundestag)
The German Green Party (German: Bündnis 90/Die Grünen – following a 1993 merger with former East German Alliance 90) has been present in the German parliament (Bundestag) continuously since 29 March 1983 as a parliamentary party. The status as a Fraktion was lost from 1990 to 1994, being demoted to a Gruppe (group), after only the East German wing managed to pass the 5% election threshold in the December 1990 German federal election.
