🇩🇪 1. Christian Democratic Union (CDU) & Christian Social Union (CSU)
Founding & ideological roots
CDU was founded in 1945 after WWII by Christian democrats, conservatives, and liberals to unify anti-socialist forces and rebuild West Germany. (Wikipedia)
Predecessors include the Catholic Centre Party and conservative factions of the Weimar Republic.
Linked to “Christian democracy”: human dignity, social market economy, and integration into Europe. (Deutschland)
CSU is the regional sister-party in Bavaria, formed in 1945 from the Bavarian People’s Party. (Wikipedia)
Internal factions & schisms
CDU has historically spanned the moderate center-right to more conservative wings, with occasional internal disputes over migration and EU policy.
CSU often pushes more conservative policies than CDU, especially on social/migration issues.
Funding & voter coalition changes
Strong support from business, industry leaders, older voters, and rural constituencies.
According to the 2025 financial reporting, CDU/CSU received the largest share of significant donations among parties. (DIE WELT)
Coalition strategies have shifted: from sole CDU governments in the early postwar era to grand coalitions with the SPD in recent decades. (German Campus)
Continuities vs. breaks
Continuity in support for the social market economy and European integration.
Breaks from earlier stances include more restrictive migration policies in recent years.
Historians & contested views
The mainstream view credits the CDU leadership with Germany’s postwar stability.
Critics argue its shift rightward on migration reflects electoral competition with AfD proponents.
🟥 2. Social Democratic Party of Germany (SPD)
Founding & ideological roots
One of the world's oldest political parties, with roots in the 19th-century labour movement. (German Campus)
Formal name since 1890; historically affiliated with trade unions and working-class politics.
Internal factions & schisms
Divisions over economic reforms: “Agenda 2010” under Gerhard Schröder sparked long-running ideological rifts between centrist moderates and traditional social democrats. (Deutsche Welle)
Funding & voter coalition changes
Historically, it drew from industrial workers and unions.
Recent decades have seen aging demographics and losses for Greens on environmental issues, and for AfD in some regions.
Continuities vs. breaks
Continues emphasis on social welfare, workers’ rights, and equality.
Some scholars see recent SPD ideology as moderated by coalition politics, thereby diluting the party's traditional social democratic character.
Contested interpretations
Some historians view SPD’s reform record (e.g., Hartz labour reforms) as adaptive modernization; critics see it as a betrayal of core principles.
💚 3. Alliance 90/The Greens
Founding & ideological roots
Originated in anti-nuclear and environmental movements of the 1970s–1980s; formalized as a political party after German reunification. (Deutsche Welle)
Combines ecological priorities with progressive social policies.
Internal factions & schisms
Early tensions between realpolitik pragmatists and radical eco-activists softened as parties entered government coalitions.
Funding & voter coalition changes
Initially supported by younger, urban, and educated voters.
As climate policy moved mainstream, Greens drew broader electorates but also faced backlash over costs and regulatory approaches.
Continuities vs. breaks
Core environmental commitments have remained stable even as the party entered government.
Historians’ perspectives
Some commentators see the Greens’ evolution as a “success story” of a movement becoming institutionalized; others warn that governing responsibilities dilute the movement's activist roots.
🟡 4. Free Democratic Party (FDP)
Founding & ideological roots
Founded in 1948 as a classical liberal party advocating individual freedoms, free markets, and civil liberties. (Deutsche Welle)
Internal factions & schisms
Internal disagreements often center on balances between civil liberties and economic liberalism.
Funding & voter coalition changes
Traditionally appeals to entrepreneurs, professionals, and self-employed voters.
Continuities vs. breaks
Consistent advocacy for low taxes and deregulation.
Recent weakness: The 2025 federal election fell below 5% threshold, prompting the leader’s resignation. (The Guardian)
Contested views
Some see FDP as a vital liberal force; critics argue its neoliberal policies widen inequality.
🔵 5. Alternative for Germany (AfD)
Founding & ideological roots
Founded in 2013 initially as a Eurosceptic, economically liberal alternative to the mainstream centre-right. (Wikipedia)
Shifted sharply right after the 2015 refugee crisis toward national conservatism and right-wing populism, with strong anti-immigration stances.
Internal factions & schisms
Factions range from more moderate economic conservatives to hard-right nationalist elements; internal power struggles (e.g., former co-founder Gauland vs. later leadership) reflect ideological tension. (Wikipedia)
Funding & voter coalition changes
Rapid growth in eastern German states; broad support from voters disillusioned with mainstream parties.
Continuities vs. breaks
Continuity in fostering nationalist, Eurosceptic sentiments.
Break from original economic liberalism toward cultural nationalism.
Contested interpretations
Germany’s domestic intelligence agency classified parts of AfD as right-wing extremist, a significant point of debate about its democratic legitimacy. (Reddit)
🟥 6. Die Linke (The Left)
Founding & ideological roots
Formed in 2007 from the post-communist Party of Democratic Socialism (successor to the East German SED) and western left groups. (Wikipedia)
Democratic socialism with an emphasis on welfare and anti-militarism.
Internal factions & schisms
