Berlin is not only a city but also a federal state of Germany and therefore has its own parliament. In Berlin, it is called the House of Representatives (Abgeordnetenhaus). It is located in the former Prussian State Parliament building in Berlin-Mitte.

It has at least 130 seats, which are filled by elected members. These belong to different parties and form parliamentary groups. Together, they decide on laws and important political issues for Berlin. The composition of the parliament depends on the election results.

The House of Representatives primarily deals with issues that directly affect Berlin, such as schools, public transport, or housing.
