Abgeordnetenhaus of Berlin

Abgeordnetenhaus of Berlin is the unicameral state parliament for the federal state of Berlin. It functions as both a city council and a Landtag under the unique constitutional status of Berlin as a city-state. The parliament is responsible for enacting state laws, electing the Governing Mayor of Berlin, and overseeing the Senate of Berlin.

History

The institution traces its origins to the Prussian estates and the city magistrates of historic Berlin. After World War II, the Allied occupation led to the division of the city, with the Berlin City Council operating in the Soviet sector. Following the Berlin Blockade and the city's formal division, the Constitution of Berlin was adopted in West Berlin in 1950, establishing the Abgeordnetenhaus as its parliament. During the Cold War, its authority was limited by the Four-Power status, with federal laws requiring approval by the Allied Kommandatura. The Peaceful Revolution of 1989 and German reunification in 1990 led to the first all-Berlin election in 1990, merging the eastern city assembly with the western Abgeordnetenhaus, a process formalized by the Unification Treaty.

Composition and election

The Abgeordnetenhaus consists of at least 130 members, though the current 20th electoral term has 159 due to leveling seats. Members are elected for a five-year term through a mixed-member proportional representation system based on the state election law. Voters cast two ballots: one for a direct candidate in one of Berlin's 78 constituencies and one for a party list. The five-percent threshold applies, though parties winning three direct mandates are exempt. Notable parties represented include the CDU, the SPD, Alliance 90/The Greens, AfD, The Left, and the FDP.

Functions and powers

As the central legislative body, the Abgeordnetenhaus passes laws on all matters within the state's competence as defined by the Basic Law, such as education, police, and cultural policy. It elects the Governing Mayor of Berlin, who then appoints the Senators to form the executive Senate of Berlin. The parliament exercises oversight through the right to interpellate members of the Senate, establish investigative committees, and receive reports from the Court of Audit. It also ratifies major international agreements affecting the state and participates in Bundesrat decisions via the Berlin government.

Building

Since 1993, the parliament has been housed in the former Prussian Landtag building on Niederkirchnerstraße in the Berlin-Mitte district, near the Martin Gropius Bau and the Topography of Terror memorial. The historic building, constructed between 1892 and 1898 by architect Friedrich Schulze, originally served the Prussian House of Representatives. It survived World War II with significant damage and was later used by the GDR's Academy of Sciences. After German reunification, it underwent extensive renovation to accommodate the merged parliament. The plenary chamber is a modern addition designed by architect Dieter G. Baumewerd.

Presidents of the Abgeordnetenhaus

The President of the Abgeordnetenhaus presides over sessions, represents the parliament, and oversees its administration. The position is traditionally held by a member of the strongest parliamentary party. Notable presidents include Otto Suhr (SPD), the first president who later became Governing Mayor of Berlin; Walter Sickert (SPD); and Ralf Wieland (SPD), who served from 2011 to 2023. The current president, elected in 2023, is Dennis Buchner of the SPD. The president is assisted by several vice presidents from other parliamentary groups.
