The Tiber (/ˈtaɪbər/ TY-bər; Italian: Tevere [ˈteːvere]; Latin: Tiberis) is the third-longest river in Italy and the longest in Central Italy, rising in the Apennine Mountains in Emilia-Romagna and flowing 406 km (252 mi) through Tuscany, Umbria, and Lazio, where it is joined by the River Aniene, to the Tyrrhenian Sea, between Ostia and Fiumicino. It drains a basin estimated at 17,375 km (6,709 sq mi). The river has achieved lasting fame as the main watercourse of the city of Rome, which was founded on its eastern banks.

The river rises at Mount Fumaiolo in Central Italy and flows in a generally southerly direction past Perugia and Rome to meet the sea at Ostia. The Tiber has advanced significantly at its mouth, by about 3 km (2 mi), since Roman times, leaving the ancient port of Ostia Antica 6 kilometres (4 miles) inland. However, it does not form a proportional delta, owing to a strong north-flowing sea current close to the shore, due to the steep shelving of the coast, and to slow tectonic subsidence.

The Etruscans (/ɪˈtrʌskən/ ih-TRUS-kən) created a civilization in Etruria in ancient Italy, with a common language and culture, and formed a federation of city-states. After adjacent lands had been conquered, its territory covered, at its greatest extent, roughly what is now Tuscany, western Umbria and northern Lazio, as well as what are now the Po Valley, Emilia-Romagna, south-eastern Lombardy, southern Veneto and western Campania.

A large body of literature has flourished on the origins of the Etruscans, but the consensus among modern scholars is that the Etruscans were an indigenous population. The earliest evidence of a culture that is identifiably Etruscan dates from about 900 BC. This is the period of the Iron Age Villanovan culture, considered to be the earliest phase of Etruscan civilization, which itself developed from the previous late Bronze Age Proto-Villanovan culture in the same region, part of the central European Urnfield culture system. Etruscan civilization dominated Italy until it fell to the expanding Rome beginning in the late 4th century BC as a result of the Roman–Etruscan Wars; Etruscans were granted Roman citizenship in 90 BC and in 27 BC the whole Etruscan territory was incorporated into the newly established Roman Empire.

The Duchy of Milan (Italian: Ducato di Milano; Lombard: Ducaa de Milan) was a state in Northern Italy, created in 1395 by Gian Galeazzo Visconti, then the lord of Milan, and a member of the important Visconti family, which had been ruling the city since 1277. At that time, it included twenty-six towns and the wide rural area of the middle Padan Plain east of the hills of Montferrat. During much of its existence, it was wedged between Savoy to the west, Republic of Venice to the east, the Swiss Confederacy to the north, and separated from the Mediterranean by the Republic of Genoa to the south. The duchy was at its largest at the beginning of the 15th century, at which time it included almost all of what is now Lombardy and parts of what are now Piedmont, Veneto, Tuscany, and Emilia-Romagna.

Under the House of Sforza, Milan experienced a period of great prosperity with the introduction of the silk industry, becoming one of the wealthiest states during the Renaissance. From the late 15th century, the Duchy of Milan was contested between the forces of the Habsburg Monarchy and the Kingdom of France. It was ruled by Habsburg Spain from 1556 and it passed to Habsburg Austria in 1707 during the War of the Spanish Succession. The duchy remained an Austrian possession until 1796 when a French army under Napoleon Bonaparte conquered it, and it ceased to exist a year later as a result of the Treaty of Campo Formio, when Austria ceded it to the new Cisalpine Republic.

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.

The Tiber Valley (Italian: Valle del Tevere) is the largest geographical part of the Tiber basin [Wikidata] of the Tiber river included in the Emilia-Romagna, Tuscany, Umbria, and the Lazio regions; it is characterized by river terraces and floodplain areas that extend from the Apennine belt up to the delta of the Tiber river in the Lazio coast [it] of the Tyrrhenian Sea.

Ravenna (/rəˈvɛnə/ rə-VEN-ə; Italian: [raˈvenna], also locally [raˈvɛn(n)a] ; Romagnol: Ravèna, Ravêna) is the capital city of the Province of Ravenna, in the Emilia-Romagna region of Northern Italy. It was the capital city of the Western Roman Empire during the 5th century until its collapse in 476, after which it served as the capital of the Ostrogothic Kingdom and then the Byzantine Exarchate of Ravenna. It has 156,444 inhabitants as of 2025.

Initially settled by the Umbri people, Ravenna came under Roman Republic control in 89 BC. Octavian built the military harbor of Classis at Ravenna, and the city remained an important seaport on the Adriatic until the early Middle Ages. The city prospered under imperial rule. In 401, Western Roman emperor Honorius moved his court from Mediolanum to Ravenna; it then served as capital of the empire for most of the 5th century.

The Ligures (Latin sg. Ligus; also Ligustici or Ligustini) or in English Ligurians, were an ancient people after whom Liguria, a region of present-day north-western Italy, is named. Because of the strong Celtic influences on their language and culture, they were also known in antiquity as Celto-Ligures and hence in English as Celto-Ligurians.

In pre-Roman times, the Ligurians occupied the present-day Italian region of Liguria, Piedmont, northern Tuscany, western Lombardy, western Emilia-Romagna, and northern Sardinia, reaching also Elba and Sicily. They inhabited also the French region of Provence-Alpes-Côte d'Azur and Corsica; however, it is generally believed that around 2000 BC the Ligurians occupied a much larger area, extending as far as what is today Catalonia (in the north-eastern corner of the Iberian Peninsula).
