Constitution of Italy in the context of "Comune"

The regions (Italian: regioni; sing. regione) are the first-level administrative divisions of the Italian Republic, constituting its second NUTS administrative level. There are twenty regions, five of which are autonomous regions with special status. Under the Constitution of Italy, each region is an autonomous entity with defined powers. With the exception of the Aosta Valley (since 1945) and Friuli-Venezia Giulia (since 2015), each region is divided into a number of provinces.

The Lateran Treaty (Italian: Patti Lateranensi; Latin: Pacta Lateranensia) was one component of the Lateran Pacts of 1929, agreements between Italy under King Victor Emmanuel III and Prime Minister Benito Mussolini and the Holy See under Pope Pius XI to settle the long-standing Roman question. The treaty and associated pacts were named after the Lateran Palace, where they were signed on 11 February 1929. The Italian Parliament ratified them on 7 June 1929.

The treaty recognised Vatican City as an independent state under the sovereignty of the Holy See. Italy also agreed to give the Catholic Church financial compensation for the loss of the Papal States. In 1948, the Lateran Treaty was recognized in the Constitution of Italy as regulating the relations between the Italian Republic and the Catholic Church. While the treaty was significantly revised in 1984, ending the status of Catholicism as the sole state religion of Italy, the Vatican remains a distinct sovereign entity to the present day.

The prime minister of Italy, officially the president of the Council of Ministers (Italian: Presidente del Consiglio dei ministri), is the head of government of the Italian Republic. The office of president of the Council of Ministers is established by articles 92–96 of the Constitution of Italy; the president of the Council of Ministers is appointed by the president of the Republic and must have the confidence of the Parliament to stay in office.

Prior to the establishment of the Italian Republic, the position was called President of the Council of Ministers of the Kingdom of Italy (Presidente del Consiglio dei ministri del Regno d'Italia). From 1925 to 1943 during the Fascist regime, the position was transformed into the dictatorial position of Head of the Government, Prime Minister, Secretary of State (Capo del Governo, Primo Ministro, Segretario di Stato) held by Benito Mussolini, Duce of Fascism, who officially governed on the behalf of the king of Italy. King Victor Emmanuel III removed Mussolini from office in 1943 and the position was restored with Marshal Pietro Badoglio becoming prime minister in 1943, although the original denomination of President of the Council was only restored in 1944, when Ivanoe Bonomi was appointed to the post of prime minister. Alcide De Gasperi became the first prime minister of the Italian Republic in 1946.

The Italian Parliament (Italian: Parlamento italiano) is the national parliament of the Italian Republic. It is the representative body of Italian citizens and is the successor to the Parliament of the Kingdom of Sardinia (1848–1861), the Parliament of the Kingdom of Italy (1861–1943), the transitional National Council (1945–1946) and the Constituent Assembly (1946–1948). It is a bicameral legislature with 600 elected members and a small number of unelected members (senatori a vita). The Italian Parliament is composed of the Chamber of Deputies (with 400 members or deputati elected on a national basis), as well as the Senate of the Republic (with 200 members or senatori elected on a regional basis, plus a small number of senators for life or senatori a vita, either appointed by the President of the Republic or former Presidents themselves, ex officio).

The two Houses are independent from one another and never meet jointly except under circumstances specified by the Constitution of Italy. By the Constitution, the two houses of the Italian Parliament possess the same powers, unlike in most parliamentary systems. Perfect bicameralism has been codified in its current form since the adoption of the Albertine Statute, and resurged after the overthrow of the fascist dictatorship of the 1920s and 1930s. No distinction is made between deputies and senators, notwithstanding that a member of parliament cannot be at the same time both a senator and a deputy; regarding presidents and vice-presidents, the precedence is given to the older one.

The Senate of the Republic (Italian: Senato della Repubblica), or simply the Senate (Italian: Senato [seˈnaːto]), is the upper house of the bicameral Italian Parliament, the lower house being the Chamber of Deputies. The two houses together form a perfect bicameral system, meaning they perform identical functions, but do so separately.

Pursuant to the Articles 57, 58, and 59 of the Italian Constitution, the Senate has 200 elective members, of which 196 are elected from Italian constituencies, and 4 from Italian citizens living abroad. Furthermore, a small number (currently 5) serve as senators for life (senatori a vita), either appointed or ex officio. It was established in its current form on 8 May 1948, but previously existed during the Kingdom of Italy as Senato del Regno (Senate of the Kingdom), itself a continuation of the Senato Subalpino (Subalpine Senate) of Sardinia established on 8 May 1848. Members of the Senate are styled Senator or The Honourable Senator (Italian: Onorevole Senatore) and they meet at Palazzo Madama, Rome.
