The Abgeordnetenhaus of Berlin is the state parliament of Berlin, Germany according to the city-state's constitution. In 1993 the parliament moved from Rathaus Schöneberg to its present house on Niederkirchnerstraße in Mitte, which until 1934 was the seat of the Prussian Landtag. The current president of the parliament is Ralf Wieland (SPD).HistoryThe Abgeordnetenhaus parliament was established by the new constitution of West Berlin in 1951. It replaced the former city legislature called Stadtverordnetenversammlung, established by the Prussian Reforms in 1808 and re-established by Allied-initiated state elections of 1946.Between 1951 and 1990 the Abgeordnetenhaus was a parliament of restricted autonomy, since the Allied Control Council required that all its legislation and its elections, such as those of mayors and the senators, be subject to Western Allied confirmation or rejection. After reunification the Abgeordnetenhaus continued to be the parliament of united Berlin.
