Historical Foundations and Merger
The origins of the party are rooted in the distinct political landscapes of West and East Germany. The Greens were established in West Germany on January 13, 1980, built upon four primary pillars: ecological wisdom, social justice, grassroots democracy, and nonviolence.
Following German reunification in 1990, the West German Greens merged with the East German Green Party. Simultaneously, Alliance 90 was formed in East Germany on September 21, 1991. These two entities eventually merged on May 14, 1993, to create the unified Alliance 90/The Greens.

The Path to Power
The party's trajectory has been marked by periods of rapid growth and strategic shifts. After entering the Bundestag in 1983, the party spent years in opposition before entering its first term as a governing party from 1998 to 2002 in coalition with the Social Democratic Party (SPD). This was followed by a second term from 2002 to 2005.

Following a period in opposition between 2005 and 2021, the party returned to the federal government in 2021 as part of a "traffic light" coalition with the SPD and the FDP. However, as of 2025, the party has returned to the opposition.

Political Platform and Ideology
Alliance 90/The Greens advocate for a comprehensive overhaul of economic and environmental policies to combat climate change. Their platform emphasizes a transition to renewable energy and a strict stance against nuclear power.
The party's anti-nuclear identity has been a defining characteristic since its inception. This commitment culminated in the permanent shutdown of eight nuclear power reactors on August 6, 2011, following the Fukushima disaster in Japan.
