Milan in the context of "Italian Fasces of Combat"

The functional urban area (FUA), previously known as larger urban zone (LUZ), is a measure of the population and expanse of metropolitan and surrounding areas which may or may not be exclusively urban. It consists of a city and its commuting zone, which is a contiguous area of spatial units that have at least 15% of their employed residents working in the city.

The FUA represents an attempt at a harmonised definition of the metropolitan area. Eurostat's objective was to have an area from which a significant share of the residents commute into the city, a concept known as the "functional urban region." To ensure a good data availability, Eurostat adjusts the FUA boundaries to administrative boundaries that approximate the functional urban area.

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.

Urban areas usually experience the urban heat island (UHI) effect; that is, they are significantly warmer than surrounding rural areas. The temperature difference is usually larger at night than during the day, and is most apparent when winds are weak, under block conditions, noticeably during the summer and winter.The main cause of the UHI effect is from the modification of land surfaces, while waste heat generated by energy usage is a secondary contributor. Urban areas occupy about 0.5% of the Earth's land surface but host more than half of the world's population. As a population center grows, it tends to expand its area and increase its average temperature. The term heat island is also used; the term can be used to refer to any area that is relatively hotter than the surrounding, but generally refers to human-disturbed areas.

Monthly rainfall is greater downwind of cities, partially due to the UHI. Increases in heat within urban centers increases the length of growing seasons, decreases air quality by increasing the production of pollutants such as ozone, and decreases water quality as warmer waters flow into area streams and put stress on their ecosystems.

In Christian theology and ecclesiology, the apostles, particularly the Twelve Apostles (also known as the Twelve Disciples or simply the Twelve), were the primary disciples of Jesus according to the New Testament. During the life and ministry of Jesus in the 1st century AD, the apostles were his closest followers and became the primary teachers of the gospel message of Jesus. There is also an Eastern Christian tradition derived from the Gospel of Luke that there were seventy apostles during the time of Jesus' ministry.

The commissioning of the Twelve Apostles during the ministry of Jesus is described in the Synoptic Gospels. After his resurrection, Jesus sent eleven of them (as Judas Iscariot by then had died) by the Great Commission to spread his teachings to all nations.

The Milan metropolitan area, also known as Grande Milano ("Greater Milan"), is the largest metropolitan area in Italy and the 54th largest in the world.

Northern Italy (Italian: Italia Settentrionale, Nord Italia, Alta Italia) is a geographical and cultural region in the northern part of Italy. The Italian National Institute of Statistics defines the region as encompassing the four northwestern regions of Piedmont, Aosta Valley, Liguria and Lombardy in addition to the four northeastern regions of Trentino-Alto Adige/Südtirol, Veneto, Friuli-Venezia Giulia and Emilia-Romagna.

With a population of 27.5 million in an area of 120,312.72 km (46,453.00 sq mi) as of 2025, the region covers roughly 40% of Italy and contains 46% of its population. Two of Italy's largest metropolitan areas, Milan and Turin, are located in the region. Northern Italy's GDP was estimated at €1 trillion in 2021, accounting for 56.5% of the Italian economy.

Mediolanum, the ancient city where Milan now stands, was originally an Insubrian city, but afterwards became an important Roman city in Northern Italy.

The city was settled by a Celtic tribe belonging to the Insubres group and belonging to the Golasecca culture under the name Medhelanon around 590 BC, conquered by the Romans in 222 BC, who Latinized the name of the city into Mediolanum, and developed into a key centre of Western Christianity and informal capital of the Western Roman Empire. It declined under the ravages of the Gothic War, its capture by the Lombards in 569, and their decision to make Ticinum the capital of their Kingdom of Italy.

Naples (/ˈneɪpəlz/ NAY-pəlz; Italian: Napoli [ˈnaːpoli] ; Neapolitan: Napule [ˈnɑːpələ]) is the regional capital of Campania and the third-largest city of Italy, after Rome and Milan, with a population of 908,082 within the city's administrative limits as of 2025, while its province-level municipality is the third most populous metropolitan city in Italy with a population of 2,958,410 residents, and the eighth most populous in the European Union. Its metropolitan area stretches beyond the boundaries of the city wall for approximately 30 kilometres (20 miles). Naples also plays a key role in international diplomacy, since it is home to NATO's Allied Joint Force Command Naples and the Parliamentary Assembly of the Mediterranean.

Founded by Greeks in the first millennium BC, Naples is one of the oldest continuously inhabited urban areas in the world. In the eighth century BC, a colony known as Parthenope (Ancient Greek: Παρθενόπη) was established on the Pizzofalcone hill. In the sixth century BC, it was refounded as Neápolis. The city was an important part of Magna Graecia, played a major role in the merging of Greek and Roman society, and has been a significant international cultural centre ever since with particular reference to the development of the arts.

Lombardy (Lombard and Italian: Lombardia; Romansh: Lumbardia) is an administrative region of Italy that covers 23,844 km (9,206 sq mi); it is located in northern Italy and has a population of about 10 million people, constituting more than one-sixth of Italy's population. Lombardy is located between the Alps mountain range and tributaries of the river Po, and includes Milan, its capital, the largest metropolitan area in the country, and among the largest in the EU.

Its territory is divided into 1,502 comuni (the region with the largest number of comuni in the entire national territory), distributed among 12 administrative subdivisions (11 provinces plus the Metropolitan City of Milan). The region ranks first in Italy in terms of population, population density, and number of local authorities, while it is fourth in terms of surface area, after Sicily, Piedmont, and Sardinia.
