Italy was a monarchy from its unification in the second half of the 19th century until 1946, when it became a parliamentary republic following a national referendum. On 1st January 1948, it adopted a constitutional charter, which defines the political and civil liberties of citizens and the principles of government. Italy is headed by a President who appoints a Prime Minister, the elected head of government. The seat of government is Rome, where the President resides in the Palazzo del Quirinale, the chamber of deputies sits in the Palazzo Montecitorio and the senate occupies the Palazzo Madama.
The President of the Italian Republic (Italian: Presidente della Repubblica Italiana) is the head of state of Italy and, in that role, represents national unity and guarantees that Italian politics comply with the Constitution. The president's term of office lasts for seven years. The 11th President of the Republic, Giorgio Napolitano, was elected on 10 May 2006, and elected to a second term for the first time in Italian Republic history, on 20 April 2013. On 31 January 2015, the incumbent President, former Constitutional judge Sergio Mattarella, was elected at the fourth ballot with 665 votes out of 1,009.
