Germany holds some of the most consequential elections in Europe. As the continent's largest economy and a founding member of the European Union, the outcome of German federal elections reverberates far beyond its borders — shaping trade policy, climate commitments, defense strategy, and the future of European integration. For anyone seeking to understand European politics, a solid grasp of how German elections work is essential.
How Germany's Electoral System Operates
Germany uses a mixed-member proportional (MMP) representation system for federal elections, widely regarded as one of the most balanced democratic designs in the world. Voters cast two votes on a single ballot:
- First vote (Erststimme): Voters choose a direct candidate to represent their local constituency. Germany has 299 constituencies, and the candidate with the most votes in each one wins a seat, similar to the "first past the post" model used in the United Kingdom.
- Second vote (Zweitstimme): Voters select a political party. This second vote is the more decisive one, as it determines the overall proportional composition of the Bundestag, Germany's federal parliament.
The 598 base seats in the Bundestag are allocated so that the party breakdown reflects the share of second votes. However, the system frequently produces overhang seats (Überhangmandate) and balance seats (Ausgleichsmandate), which can push the total number of lawmakers well beyond 598. After the 2021 election, the Bundestag swelled to a record 736 members — a figure that prompted reforms in 2023 aimed at shrinking the chamber back to a more manageable size.
A party must clear a 5% threshold or win at least three direct constituency seats to gain proportional representation in the Bundestag. This rule prevents excessive fragmentation while still allowing smaller parties a path into parliament.
The Major Political Parties
Understanding German elections requires familiarity with the country's political landscape, which features several established parties across the ideological spectrum.
CDU/CSU (Christian Democratic Union / Christian Social Union): The center-right bloc that has governed Germany for most of its postwar history. The CDU operates in all states except Bavaria, where its sister party, the CSU, takes its place. Friedrich Merz has led the CDU since 2022 and guided the bloc to victory in the February 2025 federal election.
SPD (Social Democratic Party): Germany's oldest party, positioned center-left. The SPD led the government under Olaf Scholz from 2021 to 2025 in a coalition with the Greens and the Free Democrats. The party has roots in the labor movement and traditionally emphasizes social justice and workers' rights.
The Greens (Bündnis 90/Die Grünen): A center-left party with environmental protection and climate action at its core. Under Annalena Baerbock and Robert Habeck, the Greens entered government for the first time at the federal level in 2021, holding key portfolios including foreign affairs and economic affairs.
FDP (Free Democratic Party): A liberal party focused on free-market economics, digital modernization, and civil liberties. The FDP's refusal to compromise on fiscal policy was a central factor in the collapse of the Scholz coalition in late 2024, which triggered early elections.
AfD (Alternative for Germany): A right-wing populist party that has gained significant traction, particularly in eastern Germany. The AfD has been classified as a suspected extremist organization by Germany's domestic intelligence agency, and mainstream parties have maintained a "firewall" against cooperating with it.
BSW (Bündnis Sahra Wagenknecht — Reason and Justice): Founded in 2024 by former Left Party figure Sahra Wagenknecht, BSW combines left-leaning economic positions with a more restrictive stance on immigration and a skeptical approach to foreign military engagements. The party made a notable debut in several state elections before competing in its first federal election in 2025.
Die Linke (The Left): A democratic socialist party that has struggled with declining support and internal divisions, especially after Wagenknecht's departure to form BSW.
The February 2025 Federal Election
Germany's most recent federal election took place on February 23, 2025, months ahead of the originally scheduled date. The early vote was necessitated by the dramatic collapse of Chancellor Olaf Scholz's three-party "traffic light" coalition — named after the parties' traditional colors (red for SPD, yellow for FDP, green for Greens).
The coalition had been under strain for months over disagreements on budget policy, economic strategy, and support for Ukraine. When Scholz dismissed Finance Minister Christian Lindner of the FDP in November 2024, the coalition effectively disintegrated, and snap elections were called.
The CDU/CSU, under Friedrich Merz, won the largest share of the vote and set about forming a coalition government. The election was marked by debates over Germany's sluggish economic performance, energy costs, migration policy, and the country's role in European defense amid the ongoing war in Ukraine.
The Role of the Federal President and Coalition Building
Germany's Federal President (Bundespräsident) plays a ceremonial but constitutionally important role in elections. After a federal election, the President proposes a candidate for Chancellor to the Bundestag. A candidate must win an absolute majority of votes in the Bundestag to be elected.
This requirement almost always necessitates coalition building, since no single party has won an outright majority in modern German history. Coalition negotiations can take weeks or even months, as parties must reconcile their policy positions on everything from taxation to defense spending. Coalition agreements are typically detailed documents, sometimes exceeding 150 pages, that outline the new government's policy agenda.
If the Bundestag fails to elect a Chancellor after multiple rounds of voting, the President can either appoint a minority government or dissolve the parliament and call new elections.
State Elections and Their Federal Significance
Beyond federal elections, Germany's 16 states (Länder) hold their own parliamentary elections on varying schedules. These state elections (Landtagswahlen) carry significant weight because:
- They shift the balance in the Bundesrat, Germany's upper legislative chamber, where state governments are represented. Changes in state government composition can either ease or complicate federal legislation.
- They serve as barometers of public sentiment between federal elections, often foreshadowing national trends.
- They influence internal party dynamics, with state-level success or failure affecting leadership contests and policy direction at the national level.
In 2024, state elections in Thuringia, Saxony, and Brandenburg drew international attention as the AfD achieved strong results, while BSW made an immediate impact in its first electoral tests.
Voter Turnout and Participation
German federal elections typically see voter turnout between 70% and 77%, which is higher than in many other Western democracies but has shown a gradual long-term decline. The February 2025 election saw a turnout of approximately 82.5%, the highest in decades, reflecting the heightened political stakes.
German citizens aged 18 and older are eligible to vote. The country does not have compulsory voting. Citizens living abroad can vote by mail if they have lived in Germany at some point in the past or have never resided there but have a close connection to the country.
Election Administration and Transparency
Elections in Germany are administered by federal and state returning officers, with oversight by volunteer election committees at the local level. Voting takes place primarily at polling stations on paper ballots, with postal voting widely available as an alternative.
Germany does not use electronic voting machines. After the Federal Constitutional Court raised concerns about the verifiability of electronic voting in 2009, the country returned entirely to paper ballots, prioritizing transparency and public trust in the electoral process.
International observers, including those from the Organization for Security and Co-operation in Europe (OSCE), have consistently assessed German elections as free, fair, and well-administered.
Common Misunderstandings About German Elections
A few misconceptions deserve clarification:
"The second vote is less important." In reality, the second vote is the one that determines how many seats each party receives. While the first vote matters for individual constituencies, the second vote shapes the overall parliament.
"Coalition governments are inherently unstable." While coalition negotiations can be lengthy, Germany's coalitions have generally proven durable. The postwar system was designed to encourage consensus-building, and most Germans view coalition governance as a normal and functional part of their democracy.
"The 5% threshold is undemocratic." The threshold exists to prevent the kind of extreme parliamentary fragmentation that undermined the Weimar Republic in the 1920s and 1930s. While it does limit very small parties, it has contributed to political stability in the Federal Republic for over seven decades.
Why German Elections Matter Beyond Germany
Germany is the world's third-largest economy and a driving force in the European Union. Electoral outcomes in Berlin influence EU trade negotiations, sanctions policy, migration frameworks, and climate regulation. The country's defense posture — particularly regarding NATO commitments and military aid to Ukraine — is shaped directly by whoever holds power at the federal level.
For businesses, investors, and policymakers worldwide, German elections are not merely domestic affairs. They are inflection points that signal the direction of European economic and foreign policy for years to come.
