Germany is a federal parliamentary republic, in which the Chancellor serves as the powerful head of government and the President acts as a largely ceremonial head of state. Lawmaking is shared between two chambers — the directly elected Bundestag and the Bundesrat, which represents the 16 federal states (Länder). The whole system is anchored by the Basic Law (Grundgesetz), Germany's constitution adopted in 1949, and policed by the Federal Constitutional Court in Karlsruhe.
How the Federal System Works
Germany is a federation, meaning power is deliberately divided between the central government in Berlin and 16 states, each with its own constitution, parliament, and government. States hold real authority over education, policing, and cultural affairs, while the federal level handles defence, foreign policy, currency, and most economic regulation. This division was a conscious reaction to the over-centralisation of the Nazi era, when a single regime concentrated total control.
The Basic Law sets out this structure and is intentionally difficult to undermine. Certain core principles — democracy, federalism, human dignity, and the rule of law — are protected by an "eternity clause" (Article 79.3) that cannot be amended even by a parliamentary supermajority. This guards the constitution against the kind of legal self-destruction that ended the Weimar Republic in the 1930s.
The Chancellor and the President
Real executive power rests with the Federal Chancellor, who is elected by the Bundestag and almost always leads a coalition of parties. The Chancellor sets the broad lines of government policy and appoints federal ministers. To keep the office stable, the Bundestag can only remove a sitting Chancellor through a "constructive vote of no confidence" — it must elect a replacement at the same moment, preventing a leadership vacuum.
The Federal President, by contrast, is the head of state but holds mostly ceremonial and representational duties: signing laws, formally appointing ministers, and representing Germany abroad. The President is chosen not by voters directly but by the Federal Convention, a special assembly of Bundestag members and state delegates. The result is a clear split between symbolic authority (the President) and day-to-day governing power (the Chancellor).
The Bundestag and Bundesrat
Germany has a bicameral legislature. The Bundestag is the main parliament, directly elected by citizens and home to at least 598 seats, though "overhang" and "levelling" seats can push the total higher — it reached 736 members in 2021. Voters cast two votes under a mixed-member proportional system: one for a local constituency candidate and one for a party list. This produces a parliament that closely mirrors the national share of the vote, which is why single-party majorities are rare and coalitions are the norm.
The Bundesrat represents the 16 state governments rather than voters. State cabinets send delegations whose votes must be cast as a bloc, giving the Länder a direct say over federal legislation that affects them — particularly anything touching state finances or administration. Many bills cannot pass without Bundesrat consent, making cooperation between federal and state levels essential.
The Federal Constitutional Court
The Federal Constitutional Court (Bundesverfassungsgericht), based in Karlsruhe rather than Berlin, is one of the most powerful constitutional courts in the world. It can strike down laws that violate the Basic Law, settle disputes between the federal government and the states, and even ban political parties judged hostile to the democratic order. Ordinary citizens can bring a "constitutional complaint" directly to the court if they believe their basic rights have been breached, making it a genuine guardian of individual liberties. Its rulings carry enormous weight and have repeatedly reshaped German law and policy.
From Division to Reunification
Modern German governance grew out of a turbulent history: unification under Bismarck in 1871, the fragile Weimar Republic, the Nazi dictatorship, and post-war division into East and West. West Germany adopted the Basic Law in 1949 as a supposedly temporary framework. When the Berlin Wall fell, reunification in 1990 simply extended that constitution to the formerly communist East, uniting the country under one democratic system. Today Germany is the European Union's most populous member and largest economy, and a central force in EU decision-making. For more background, see our germany country guide.
