Italy is located in Southern Europe and comprises the long, boot-shaped Italian Peninsula, the land between the peninsula and the Alps, and a number of islands including Sicily and Sardinia. Its total area is 301,230 km², of which 294,020 km² is land and 7,210 km² is water.
Including islands, Italy has a coastline and border of 7,600 km on the Adriatic, Ionian, Tyrrhenian seas (740 km), and borders shared with France (488 km), Austria (430 km), Slovenia (232 km) and Switzerland; San Marino (39 km) and the Vatican City (3.2 km), both entirely surrounded by Italy, account for the remainder.
The Apennine Mountains form the peninsula's backbone; the Alps form its northern boundary. The largest of its northern lakes is Garda (143 sq mi/370 km2); in the centre is Trasimeno Lake. The Po, Italy's principal river, flows from the Alps on the western border and crosses the great Padan plain to the Adriatic Sea. Several islands form part of Italy; the largest are Sicily (9,926 sq mi/25,708 km2) and Sardinia (9,301 sq mi/24,089 km2).

Volcanism
Main article: Volcanism in Italy
See also: List of volcanoes in Italy
Italy is a volcanically active country, containing the only active volcano in mainland Europe. The country's volcanism is due chiefly to the presence, a short distance to the south, of the boundary between the Eurasian Plate and the African Plate. The magma erupted by Italy's volcanoes is thought to result from the upward forcing of rocks melted by the subduction of one plate below another.
There are several active volcanoes in Italy: Etna, the second-largest active volcano in Europe;[49] Vulcano; Stromboli; and Vesuvius, the only active volcano on the mainland of Europe.

Climate

Main article: Climate of Italy
The climate in Italy is highly diverse and can be far from the stereotypical Mediterranean climate depending on the location. Most of the inland northern areas of Italy, for example Turin, Milan and Bologna, have a continental climate often classified as humid subtropical (Köppen climate classification Cfa). The coastal areas of Liguria and most of the peninsula south of Florence generally fit the Mediterranean stereotype (Köppen climate classification Csa). The coastal areas of the peninsula can be very different from the interior higher altitudes and valleys, particularly during the winter months when the higher altitudes tend to be cold, wet, and often snowy. The coastal regions have mild winters and warm and generally dry summers, although lowland valleys can be quite hot in summer.

Nature

Italy is one of the richest countries in Europe and in the Mediterranean basin in terms of species biodiversity. The Italian flora is the richest in Europe. Traditionally it was estimated to comprise about 5,500 vascular plant species. However, as of 2004, 6,759 species are recorded in the Data bank of Italian vascular flora.[50] (9,000 plant species if non-vascular species are included, half Europe’s total). The nation has one of the highest levels of faunal biodiversity in Europe with over 57,000 species recorded (more than a third of all European fauna). This is due to Italy’s *Southerly geographical position, surrounded by the Mediterranean and Aegean seas. There is 8,000 km of coastline and the Italian peninsula is in the centre of the Mediterranean Sea, forming a corridor between central Europe and North Africa. Italy also receives species from the Balkans, Eurasia and the Middle East.
Varied geological structure and soils.
High mountain ranges, especially the Alps and the Apennines.
Climate and habitat diversity.
86% of the Italian fauna is land-based, 14% is aquatic. Insects represent about two thirds of all of Italy’s fauna.

Government and politics
Main article: Politics of Italy
See also: List of Prime Ministers of Italy and List of Presidents of the Italian Republic

President of the Republic Giorgio Napolitano.
The politics of Italy take place in a framework of a parliamentary, democratic republic, and of a multi-party system. Executive power is exercised collectively by the Council of Ministers, which is led by a President (Presidente del Consiglio dei Ministri), informally referred to as "premier" or primo ministro (that is, "prime minister"). Legislative power is vested in the two houses of Parliament primarily, and secondarily in the Council of Ministers. The judiciary is independent of the executive and the legislative. Italy has been a democratic republic since 2 June 1946, when the monarchy was abolished by popular referendum (see "birth of the Italian Republic"). The constitution was promulgated on 1 January 1948.
Giorgio Napolitano is the President of the Italian Republic, whilst Silvio Berlusconi is the nation's Prime Minister (President of the Council of Ministers).
The President of the Italian Republic (Presidente della Repubblica) is elected for seven years by the parliament sitting jointly with a small number of regional delegates. As the head of state, the President of the Republic represents the unity of the nation and has many of the duties previously given to the King of Italy. The president serves as a point of connection between the three branches of power: he is elected by the lawmakers, he appoints the executive, he is the president of the judiciary and he is also the commander-in-chief of the armed forces.

The Quirinal Palace, which is the official residence of the President of the Italian Republic.
The president nominates the Prime Minister, who proposes the other ministers (formally named by the president). The Council of Ministers must obtain a confidence vote from both houses of Parliament. Legislative bills may originate in either house and must be passed by a majority in both.
Italy elects a parliament consisting of two houses, the Chamber of Deputies (Camera dei Deputati), which has 630 members and the Senate of the Republic (Senato della Repubblica), comprising 315 elected members and a small number of senators for life). Legislation may originate in either house and must be passed in identical form by a majority in each. The houses of parliament are popularly and directly elected through a complex electoral system (latest amendment in 2005) which combines proportional representation with a majority prize for the largest coalition. All Italian citizens 18 years of age and older can vote. However, to vote for the Senate, the voter must be 25 or older.
The electoral system for the Senate is based upon regional representation. As of 15 May 2006 there are seven life senators (of which three are former Presidents). Both houses are elected for a maximum of five years, but both may be dissolved by the President before the expiration of their normal term if the Parliament is unable to elect a stable government. In post-war history, this has happened in 1972, 1976, 1979, 1983, 1994, 1996, and 2008.
A peculiarity of the Italian Parliament is the representation given to Italian citizens permanently living abroad (about 2.7 million people). Among the 630 Deputies and the 315 Senators there are respectively 12 and 6 elected in four distinct overseas constituencies. Those members of Parliament were elected for the first time in April 2006, and they have the same rights as members elected in Italy.

Law
The Italian judicial system is based on Roman law modified by the Napoleonic code and later statutes. The Supreme Court of Cassation is the court of last resort for most disputes. The Constitutional Court of Italy (Corte Costituzionale) rules on the conformity of laws with the Constitution and is a post-World War II innovation.

US President Barack Obama meets with Italian Prime Minister Silvio Berlusconi
Italy was a founding member of the European Community—now the European Union (EU). Italy was admitted to the United Nations in 1955 and is a member and strong supporter of the North Atlantic Treaty Organization (NATO), the Organisation for Economic Co-operation and Development (OECD), the General Agreement on Tariffs and Trade/World Trade Organization (GATT/WTO), the Organization for Security and Co-operation in Europe (OSCE), the Council of Europe, and the Central European Initiative. Its recent turns in the rotating Presidency of international organisations include the Conference for Security and Co-operation in Europe (CSCE), the forerunner of the OSCE, in 1994; G8; and the EU in 2001 and from July to December 2003.
Italy supports the United Nations and its international security activities. Italy deployed troops in support of UN peacekeeping missions in Somalia, Mozambique, and East Timor and provides support for NATO and UN operations in Bosnia, Kosovo and Albania. Italy deployed over 2,000 troops to Afghanistan in support of Operation Enduring Freedom (OEF) in February 2003. Italy still supports international efforts to reconstruct and stabilize Iraq, but it has withdrawn its military contingent of some 3,200 troops as of November 2006, maintaining only humanitarian workers and other civilian personnel. In August 2006 Italy sent about 2,450 soldiers to Lebanon for the United Nations' peacekeeping mission UNIFIL.[51] Furthermore, since 2 February 2007 an Italian, Claudio Graziano, is the commander of the UN force in the country.

“
Italy rejects war as an instrument of aggression against the freedoms of other peoples and as a means for settling international controversies; it agrees, on conditions of equality with other states, to the limitations of sovereignty necessary for an order that ensures peace and justice among Nations; it promotes and encourages international organizations having such ends in view.
”
—Article 11 of Italian Constitution
The Italian armed forces are under the command of the Supreme Defence Council, presided over by the President of the Italian Republic. In 2008 the military had 186,798 personnel on active duty, along with 114,778 in the national gendarmerie.[52] As part of NATO's nuclear sharing strategy Italy also hosts 90 United States nuclear bombs, located in the Ghedi Torre and Aviano air bases.[53] Total military spending in 2007 was $33.1 billion, equal to 1.8% of national GDP.[54]
The Italian armed forces are divided into four branches:

Main article: Aeronautica Militare

The Eurofighter is built by a consortium of Italy and three other countries.
The Italian Air Force in 2008 has a strength of 43,882 and operates 585 aircraft, including 219 combat jets and 114 helicopters. As a stopgap and as replacement for leased Tornado ADV interceptors, the AMI has leased 30 F-16A Block 15 ADF and four F-16B Block 10 Fighting Falcons, with an option for more.
The coming years also will see the introduction of 121 EF2000 Eurofighter Typhoons, replacing the leased F-16 Fighting Falcons. Further updates are foreseen in the Tornado IDS/IDT and AMX fleets. A transport capability is guaranteed by a fleet of 22 C-130Js and Aeritalia G.222s of which 12 are being replaced with the newly developed G.222 variant called the C-27J Spartan.

Gendarmerie
Main article: Carabinieri
The Carabinieri are the gendarmerie and military police of Italy, providing the republic with a national police service. At the Sea Islands Conference of the G8 in 2004, the Carabinieri was given the mandate to establish a Center of Excellence for Stability Police Units (CoESPU) to spearhead the development of training and doctrinal standards for civilian police units attached to international peacekeeping missions.[56]
