Italy, officially the Italian Republic, is a country in Southern and Western Europe. It consists of a peninsula that extends into the Mediterranean Sea, with the Alps on its northern land border, as well as nearly 800 islands, notably Sicily and Sardinia. Italy shares land borders with France to the west; Switzerland and Austria to the north; Slovenia to the east; and the two enclaves of Vatican City and San Marino. It is the tenth-largest country in Europe by area, covering 301,340 km (116,350 sq mi), and the third-most populous member state of the European Union, with nearly 59 million inhabitants. Italy's capital and largest city is Rome; other major cities include Milan, Naples, Turin, Palermo, Bologna, Florence, Genoa, and Venice.

The history of Italy goes back to numerous Italic peoples – notably including the ancient Romans, who conquered the Mediterranean world during the Roman Republic and ruled it for centuries during the Roman Empire. With the spread of Christianity, Rome became the seat of the Catholic Church and the Papacy. Barbarian invasions and other factors led to the decline and fall of the Western Roman Empire between late antiquity and the Early Middle Ages. By the 11th century, Italian city-states and maritime republics expanded, bringing renewed prosperity through commerce and laying the groundwork for modern capitalism. The Italian Renaissance flourished during the 15th and 16th centuries and spread to the rest of Europe. Italian explorers discovered new routes to the Far East and the New World, contributing significantly to the Age of Discovery.

The Adriatic Sea (/ˌeɪdriˈætɪk/) is a body of water separating the Italian Peninsula from the Balkan Peninsula. The Adriatic is the northernmost arm of the Mediterranean Sea, extending from the Strait of Otranto (where it connects to the Ionian Sea) to the northwest and the Po Valley. The countries with coasts on the Adriatic are Albania, Bosnia and Herzegovina, Croatia, Italy, Montenegro, and Slovenia.

The Adriatic contains more than 1,300 islands, mostly located along its eastern coast. It is divided into three basins, the northern being the shallowest and the southern being the deepest, with a maximum depth of 1,233 metres (4,045 ft). The prevailing currents flow counterclockwise from the Strait of Otranto. Tidal movements in the Adriatic are slight, although larger amplitudes occur occasionally. The Adriatic's salinity is lower than the Mediterranean's because it collects a third of the fresh water flowing into the Mediterranean, acting as a dilution basin. The surface water temperatures generally range from 30 °C (86 °F) in summer to 12 °C (54 °F) in winter, significantly moderating the Adriatic Basin's climate. The Adriatic Sea sits on the Apulian or Adriatic Microplate. In the Late Oligocene, the Italian Peninsula first formed, separating the Adriatic Basin from the rest of the Mediterranean. The western coast is alluvial or terraced, while the eastern coast is highly indented with pronounced karstification. There are dozens of marine protected areas in the Adriatic, designed to protect the sea's habitats and biodiversity—more than 7,000 species are identified as native to the Adriatic, many of them endemic, rare and threatened ones.

The Slavs or Slavic people are a major ethnic group in Europe. They speak Slavic languages and preserve Slavic culture. There are 13 Slavic countries in Europe, which include: Poland, the Czech Republic, Slovakia, Russia, Belarus, Ukraine, Slovenia, Croatia, Bosnia and Herzegovina, Serbia, Montenegro, North Macedonia, and Bulgaria; the Slavs comprise a population of around 300 million people. There are three different Slavic ethnic groups: the West Slavs, the East Slavs, and the South Slavs; the Poles, Silesians, Kashubians, Sorbs, Czechs, and Slovaks are West Slavs; Russians, Belarusians, Ukrainians, and Rusyns are East Slavs; while Slovenes, Resians, Croats, Bosniaks, Serbs, Montenegrins, Torlakians, the Gorani, the Torbeši, Macedonians, and Bulgarians are South Slavs. Slavs are geographically distributed throughout the northern parts of Eurasia; they predominantly inhabit Central Europe, Eastern Europe, Southeastern Europe, and Northern Asia, though there is a large Slavic minority scattered across the Baltic states and Central Asia, and a substantial Slavic diaspora in the Americas, Western Europe, and Northern Europe.

Early Slavs lived during the Migration Period and the Early Middle Ages (approximately from the 5th to the 10th century AD), and came to control large parts of Central, Eastern, and Southeast Europe between the sixth and seventh centuries. Beginning in the 7th century, they were gradually Christianized. By the 12th century, they formed the core population of a number of medieval Christian states: East Slavs in the Kievan Rus', South Slavs in the Bulgarian Empire, the Principality of Serbia, the Duchy of Croatia and the Banate of Bosnia, and West Slavs in the Principality of Nitra, Great Moravia, the Duchy of Bohemia, and the Kingdom of Poland.

Southern Europe is also known as Mediterranean Europe, as its geography is marked by the Mediterranean Sea. Definitions of southern Europe include some or all of these countries and regions: Albania, Andorra, Bosnia and Herzegovina, Bulgaria, Croatia, Cyprus, Gibraltar, Greece, Italy, Kosovo, Malta, Monaco, Montenegro, North Macedonia, Portugal, San Marino, Serbia, Slovenia, southern France, southern Romania, Spain, Ticino (Switzerland), Turkey, and Vatican City.

Southern Europe is focused on the three peninsulas located in the extreme south of the European continent. These are the Iberian Peninsula, the Italian Peninsula, and the Balkan Peninsula. These three peninsulas are separated from the rest of Europe by towering mountain ranges, respectively by the Pyrenees, the Alps and the Balkan Mountains. The location of these peninsulas in the heart of the Mediterranean Sea, as well as their mountainous reliefs, provide them with very different types of climates (mainly subtropical Mediterranean) from the rest of the continent. So, the Sirocco hot wind that originates in the heart of the Sahara blows over Italy, going up to the interior of the Alpine arc (Po Valley). The Alps prevent the Sirocco from spreading to the rest of Europe. And, conversely, the Alps and the Pyrenees protect the Italian and Iberian Peninsulas from the rains and icy winds from the south of France such as the Mistral and the Tramontane. When the Mistral and the Tramontane are blowing, this provokes an "upwelling" phenomenon on the French coast. They push the surface waters out to sea and bring deeper, cooler waters up to the seaside. Consequently, the temperature of the waters of the French coasts are therefore very cool even in summer, and not representative of the rest of the Mediterranean.This same kind of phenomenon takes place between the two slopes of the Balkan mountain range. These mountains have, moreover, been a serious handicap to population displacement, focusing southern Europe mainly on the Mediterranean world. The climate and cultures are therefore very specific.

Italian (italiano, pronounced [itaˈljaːno] , or lingua italiana, pronounced [ˈliŋɡwa itaˈljaːna]) is a Romance language of the Indo-European language family. It evolved from the colloquial Latin of the Roman Empire, and is the least divergent language from Latin, together with Sardinian. It is spoken by 68 to 85 million people, including 64 million native speakers as of 2024. Some speakers of Italian are native bilinguals of both Italian (either in its standard form or regional varieties) and a local language of Italy, most frequently the language spoken at home in their place of origin.

Italian is an official language in Italy, San Marino, Switzerland (Ticino and the Grisons), and Vatican City, and it has official minority status in Croatia, Slovenia (Istria), Romania, Bosnia and Herzegovina, and in 6 municipalities of Brazil. It is also spoken in other European and non-EU countries, most notably in Malta (by 66% of the population), Albania and Monaco, as well as by large immigrant and expatriate communities in the Americas, Australia and on other continents.

The Italian geographic region, Italian physical region or Italian region is a geographical region of Southern Europe delimited to the north by the mountain chains of the Alps. This subregion is composed of a peninsular and continental part and an insular part. Located between the Balkan Peninsula and the Iberian Peninsula, it protrudes into the centre of the Mediterranean Sea and overlooks the Adriatic Sea, the Ionian Sea, the Ligurian Sea, the Sardinian Channel, the Sea of Corsica, the Sea of Sardinia, the Strait of Sicily, and the Tyrrhenian Sea.

The Italian geographic region, in its traditional and most widely accepted extent, has an area of approximately 324,000 square kilometres (125,000 sq mi), which is greater than the area of the entire Italian Republic (301,230 square kilometres (116,310 sq mi)). The region also includes territories that are sovereign parts of Croatia, France, Slovenia, and Switzerland, as well as the four small sovereign states of the Principality of Monaco, the Republic of Malta, the Republic of San Marino, and the Vatican City State (the Holy See).

The Alps (/ælps/) are some of the highest and most extensive mountain ranges in Europe, stretching approximately 1,200 km (750 mi) across eight Alpine countries (from west to east): Monaco, France, Switzerland, Italy, Liechtenstein, Germany, Austria and Slovenia.

The Alpine arch extends from Nice on the western Mediterranean to Trieste on the Adriatic and Vienna at the beginning of the Pannonian Basin. The mountains were formed over tens of millions of years as the African and Eurasian tectonic plates collided. Extreme shortening caused by the event resulted in marine sedimentary rocks rising by thrusting and folding into high mountain peaks such as Mont Blanc and the Matterhorn.

Austria, formally the Republic of Austria, is a landlocked country in Central Europe, lying in the Eastern Alps. It is a federation of nine states, of which the capital Vienna is the most populous city and state. Austria is bordered by Germany to the northwest, the Czech Republic to the north, Slovakia to the northeast, Hungary to the east, Slovenia and Italy to the south, and Switzerland and Liechtenstein to the west. The country occupies an area of 83,879 km (32,386 sq mi) and has a population of around 9 million.

The area of today's Austria has been inhabited since at least the Paleolithic period. Around 400 BC, it was inhabited by the Celts and then annexed by the Romans in the late 1st century BC. Christianization in the region began in the 4th and 5th centuries, during the late Roman period, followed by the arrival of numerous Germanic tribes during the Migration Period.

The Illyrians (Ancient Greek: Ἰλλυριοί, Illyrioi; Latin: Illyrii) were a group of Indo-European-speaking people who inhabited the western Balkan Peninsula in ancient times. They constituted one of the three main Paleo-Balkan populations, along with the Thracians and Greeks.

The territory the Illyrians inhabited came to be known as Illyria to later Greek and Roman authors, who identified a territory that corresponds to most of Albania, Montenegro, Kosovo, much of Croatia and Bosnia and Herzegovina, western and central Serbia and some parts of Slovenia between the Adriatic Sea in the west, the Drava river in the north, the Morava river in the east and the Ceraunian Mountains in the south. The first account of Illyrian people dates back to the 6th century BC, in the works of the ancient Greek writer Hecataeus of Miletus.
