Tiber

The Umbri were an ancient people, considered an Italic people, attested during the Iron Age in inner central Italy, approximately between the middle Tiber river and the central Apennines. A region called Umbria still exists and is now occupied by Italian speakers. It is somewhat smaller than the ancient Umbria. Most ancient Umbrian cities were settled in the 9th-4th centuries BC on easily defensible hilltops. Umbria was bordered by the Tiber and Nar rivers and included the Apennine slopes on the Adriatic. The ancient Umbrian language belongs to the Osco-Umbrian branch of the Italic languages, an Indo-European subfamily that also includes the Latino-Faliscan languages.

The Battle of the Allia was fought c. 387 BC between the Senones – a Gallic tribe led by Brennus, who had invaded Northern Italy – and the Roman Republic.

The battle was fought at the confluence of the Tiber river and Allia brook, 11 Roman miles (16 km, 10 mi) north of Rome. The Romans were routed and subsequently Rome was sacked by the Senones. According to scholar Piero Treves, "the absence of any archaeological evidence for a destruction-level of this date suggests that [this] sack of Rome was superficial only."

Città di Castello (Italian pronunciation: [tʃitˈta ddi kasˈtɛllo], lit. 'Castle Town') is a city and comune (municipality) in the province of Perugia, in the northern part of Umbria. It is situated on a slope of the Apennines, on the flood plain along the upper part of the river Tiber. The city is 56 km (35 mi) north of Perugia and 104 km (65 mi) south of Cesena, Emilia-Romagna, on the highway SS 3 bis. It is connected by the SS 73 with Arezzo, Tuscany, and the A1 highway, situated 38 km (23 mi) west. The comune of Città di Castello has an exclave named Monte Ruperto within Marche.

The Ponte Salario, also called Ponte Salaro during the Middle Ages, is a road bridge in Rome, Italy, whose origins date back to the Roman period. In antiquity, it lay outside the city limits, 3 km north of the Porta Collina, at the point where the Via Salaria (modern SS4) crossed the Aniene, a tributary of the Tiber. The visible side arches are assumed to originate from the first stone structure built during the 1st century BC.

In the Gothic War (535–554), the main arch was largely destroyed by the Ostrogothic king Totila, but repaired by his East Roman opponent Narses in 565, who recorded the extensive restoration works, including a river diversion, in an extant bridge inscription. At that time, the Ponte Salario was 72 m long and 6.52 m wide, with its semi-circular arch reaching a remarkable clear span of 24.86 m.

The Arno is a river in the Tuscany region of Italy. It is the most important river of central Italy after the Tiber.

Latin (lingua Latina or Latinum) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally spoken by the Latins in Latium (now known as Lazio), the lower Tiber area around Rome, Italy. Through the expansion of the Roman Republic, it became the dominant language in the Italian Peninsula and subsequently throughout the Roman Empire. It has greatly influenced many languages, including English, having contributed many words to the English lexicon, particularly after the Christianisation of the Anglo-Saxons and the Norman Conquest. Latin roots appear frequently in the technical vocabulary used by fields such as theology, the sciences, medicine, and law.

By the late Roman Republic, Old Latin had evolved into standardised Classical Latin. Vulgar Latin refers to the less prestigious colloquial registers, attested in inscriptions and some literary works such as those of the comic playwrights Plautus and Terence and the author Petronius. While often called a "dead language", Latin did not undergo language death. Between the 6th and 9th centuries, natural language change in the vernacular Latin of different regions evolved into distinct Romance languages. After the fall of the Western Roman Empire, Latin remained the common language of international communication, science, scholarship and academia in Europe into the early 19th century, by which time modern languages had supplanted it in common academic and political usage.

Sabina (Latin: Sabinum), also called the Sabine Hills, is a region in central Italy. It is named after Sabina, the territory of the ancient Sabines, which was once bordered by Latium to the south, Picenum to the east, ancient Umbria to the north and Etruria to the west. It was separated from Umbria by the River Nar, today's Nera, and from Etruria by the River Tiber.
