The 2025 Bundestagswahl: What You Need to Know
The German federal election on February 23, 2025 was one of the most consequential in decades. The SPD-led traffic light coalition (Ampelkoalition) of SPD, Greens, and FDP collapsed in November 2024 over budget disputes, forcing snap elections. The CDU/CSU won the most votes, the AfD came second, and the FDP failed to pass the 5% threshold for the first time since 2013.
German Electoral System: How Seats Are Allocated
Germany uses a mixed-member proportional representation (MMPR) system. Voters cast two votes: the Erststimme (first vote) for a direct constituency candidate, and the Zweitstimme (second vote) for a party list. The second vote determines the overall seat distribution via the Sainte-Lague method. The 2023 Wahlrechtsreform capped the Bundestag at exactly 630 seats.
Frequently Asked Questions
What happened in the German federal election 2025?
The German Bundestagswahl took place on February 23, 2025. The CDU/CSU won approximately 28.5%, the AfD came second with 20.8%, and the SPD fell to 16.4%. The Greens received 11.6%, the FDP failed to pass the 5% threshold at 4.3%, and the BSW also failed with 4.97%. The new Bundestag had to form a new government without the old SPD-led coalition.
How does the German coalition formation work?
After a German federal election, the party with the most seats typically gets the first chance to form a coalition government. A coalition needs a majority of 316+ seats in the 630-seat Bundestag. Coalition negotiations (Koalitionsverhandlungen) can take weeks or months. The Koalitionsvertrag (coalition treaty) must then be signed, and a Chancellor (Bundeskanzler) is elected by the Bundestag.
What is the 5% threshold in German elections?
The Funf-Prozent-Hurde (5% threshold) requires political parties to receive at least 5% of the second votes (Zweitstimmen) nationally to enter the Bundestag. Alternatively, a party can enter if it wins at least 3 direct constituency seats (Direktmandate). The FDP famously failed to pass this threshold in 2025, leaving the Bundestag for the first time since 2013.
What is a grand coalition (Groe Koalition) in Germany?
A Groe Koalition (GroKo) is a coalition between the two largest parties, typically CDU/CSU and SPD. Germany has had several GroKo governments: 1966-69, 2005-09, 2013-17, and 2018-21. A GroKo is generally seen as politically less dynamic but more stable, as it commands a large parliamentary majority but reduces the visible political opposition.
Who became German Chancellor after the 2025 election?
Friedrich Merz of the CDU became German Chancellor (Bundeskanzler) in April 2025 after the CDU/CSU negotiated a coalition with the SPD, forming a new grand coalition (GroKo). This was despite initial resistance from both parties. The coalition agreement covers key topics including migration policy, economic stimulus, and defense spending increases to meet NATO 2% targets.
How many seats are in the German Bundestag?
The German Bundestag was reformed to have exactly 630 seats from the 2025 election onward, following the Wahlrechtsreform (electoral reform). Previously, the Bundestag had grown to 736 seats due to overhang and leveling mandates. A majority government requires 316+ seats. The reform eliminated overhang seats by allowing direct mandate winners to be allocated to party list seats.
