In the 1980s and 1990s, a dispute between the Fundis and the Realos with the German Green Party arose. While the Realos, the group around Joschka Fischer , were in favor of moderate policies and cabinet cooperation, the Fundis opposed cabinet cooperation.

The term was first used in the Hessen Green party. In the 1982 state elections the party gained 8% of vote, and neither the SPD or the CDU had a majority of their own. In their program Hessen Greens had claimed that there was a “fundamental opposition between the anti-life and anti-democratic policies of the SPD, CDU and FDP.” Those who had a coalition with the SPD were called Fundis. The Greens tolerated an SPD- minority government for three years and in 1985 they entered the coalition, a victory for the Realos. Joschka Fischer became their minister.
During the party congress on 22-23 June 1985 in Hagen, the Realos won a victory on the federal level when they adopted a motion, saying that the Greens could “use the full bandwidth of parliamentary possibilities” “. At the end of the 1980s the Fundis founded the Left Forum. In 1990 a group of prominent eco-socialists left the party, in 1991 a group of deep greens also left. Some of those joined the PDS and others
In 1998 the Greens joined the federal cabinet, a final victory for the Realos. In the following years the division between realos and Fundis becomes less important. [ quote needed ]
