Passage: The Parliament of Austria is located in Vienna, the country's largest city and capital. Austria became a federal, representative democratic republic through the Federal Constitution of 1920. The political system of the Second Republic with its nine states is based on the constitution of 1920, amended in 1929, which was reenacted on 1 May 1945.The head of state is the Federal President (Bundespräsident), who is directly elected by popular vote. The chairman of the Federal Government is the Federal Chancellor, who is appointed by the President. The government can be removed from office by either a presidential decree or by vote of no confidence in the lower chamber of parliament, the Nationalrat. Voting for the Federal President and for the Parliament used to be compulsory in Austria, but this was abolished in steps from 1982 to 2004.The Parliament of Austria consists of two chambers. The composition of the Nationalrat (183 seats) is determined every five years (or whenever the Nationalrat has been dissolved by the federal president on a motion by the federal chancellor, or by Nationalrat itself) by a general election in which every citizen over 16 years (since 2007) has voting rights. While there is a general threshold of 4% for all parties at federal elections (Nationalratswahlen), there remains the possibility to gain a direct seat, or Direktmandat, in one of the 43 regional election districts.
