Claim: Italy is a sovereign state.

Italy -LRB- Italia -LSB- iˈtaːlja -RSB- -RRB- , officially the Italian Republic -LRB- -LSB- Repubblica italiana , links = no -RSB- -RRB- , is a unitary parliamentary republic in Europe.The Italian peninsula is geographically located in Southern Europe , while North Italy can be placed partly or totally in Central Europe . Due to cultural , political and historical reasons , Italy is a Western European country . Located in the heart of the Mediterranean Sea , Italy shares open land borders with France , Switzerland , Austria , Slovenia , San Marino and Vatican City . Italy covers an area of 301338 km2 and has a largely temperate seasonal and Mediterranean climate . Due to its shape , it is often referred to in Italy as lo Stivale -LRB- the Boot -RRB- . With 61 million inhabitants , it is the fourth most populous EU member state .   Since classical times , ancient Phoenicians , Carthaginians and Greeks established settlements in the south of Italy , with Etruscans and Celts inhabiting the centre and north of Italy respectively and various different ancient Italian tribes and Italic peoples dispersed throughout the Italian Peninsula and insular Italy . The Italic tribe known as the Latins formed the Roman Kingdom , which eventually became a republic that conquered and assimilated other nearby civilisations . Rome ultimately emerged as the dominant power in the Mediterranean basin , conquering much of the ancient world and becoming the leading cultural , political and religious centre of Western civilisation . The legacy of the Roman Empire is widespread and can be observed in the global distribution of civilian law , republican governments , Christianity and the Latin script .   During the Middle Ages , Italy suffered sociopolitical collapse amid calamitous barbarian invasions , but by the 11th century numerous rival city-states and maritime republics rose to great prosperity through shipping , commerce and banking , laying down the groundwork for modern capitalism . These independent statelets , acting as Europe 's main trading hubs with Asia and the Near East , often enjoyed a greater degree of democracy and wealth in comparison to the larger feudal monarchies that were consolidating throughout Europe at the time , though much of central Italy remained under the control of the theocratic Papal States , while Southern Italy remained largely feudal until the 19th century , partially as a result of a succession of Byzantine , Arab , Norman , Spanish and Bourbon conquests of the region .   The Renaissance began in Italy and spread to the rest of Europe , bringing a renewed interest in humanism , science , exploration and art . Italian culture flourished at this time , producing famous scholars , artists and polymaths such as Leonardo da Vinci , Galileo , Michelangelo and Machiavelli . Italian explorers such as Marco Polo , Christopher Columbus , Amerigo Vespucci and Giovanni da Verrazzano discovered new routes to the Far East and the New World , helping to usher in the European Age of Discovery . Nevertheless , Italy 's commercial and political power significantly waned with the opening of the Atlantic trade route and the route to the Indian Ocean via the Cape of Good Hope , which bypassed the Mediterranean . Furthermore , the Italian city-states constantly engaged one another in bloody warfare , culminating in the Italian Wars of the 15th and 16th centuries that left them exhausted , with no one emerging as a dominant power . The weakened sovereigns soon fell victim to conquest by European powers such as France , Spain and Austria .   By the mid-19th century , a rising movement in support of Italian nationalism and independence from foreign control led to a period of revolutionary political upheaval known as the Risorgimento , which sought the formation of a unified nation-state . After various unsuccessful attempts , the Italian Wars of Independence and the Expedition of the Thousand resulted in the eventual unification of the country in 1861 , now a great power after centuries of foreign domination and political division . From the late 19th century to the early 20th century , the new Kingdom of Italy rapidly industrialised , although mainly in the north , and acquired a colonial empire , while the south remained largely impoverished and excluded from industrialisation , fuelling a large and influential diaspora . Despite being one of the main victors in World War I , Italy entered a period of economic crisis and social turmoil , leading the way to the rise of a fascist dictatorship in 1922 . The subsequent participation in World War II on the Axis side ended in military defeat , economic destruction and an Italian civil war . Following the liberation of Italy and the rise of the resistance , the country abolished the monarchy , reinstated democracy , enjoyed a prolonged economic boom and , despite periods of sociopolitical turmoil -LRB- e.g. Anni di piombo , Mani pulite , the Second Mafia War , the Maxi Trial and subsequent assassinations of anti-mafia officials -RRB- , became a major developed country .   Today , Italy has the third largest economy in the Eurozone and the eighth largest in the world . It has a very high level of human development and is ranked sixth in the world for life expectancy . The country plays a prominent role in regional and global economic , military , cultural and diplomatic affairs , and it is both a regional power and a great power . Italy is a founding and leading member of the European Union and the member of numerous international institutions , including the UN , NATO , the OECD , the OSCE , the WTO , the G7/G8 , G20 , the Union for the Mediterranean , the Council of Europe , Uniting for Consensus and many more . As a reflection of its cultural wealth , Italy is home to 51 World Heritage Sites , the most in the world , and is the fifth most visited country .
