Its capital is Bologna. It has a population of over 4.4 million in an area of 22,509.67 km (8,691 sq mi).

Emilia-Romagna is one of the wealthiest and most developed regions in Europe, with the third highest gross domestic product per capita in Italy. It is also a cultural center, being the home of the University of Bologna, the oldest university in the world. Some of its cities, such as Modena, Parma, Ferrara, and Ravenna, are UNESCO heritage sites. It is a center for food and automobile production (such as Ferrari, Lamborghini, and Maserati). It has coastal resorts such as Cervia, Cesenatico, and Rimini. In 2018, the Lonely Planet guide named Emilia-Romagna as the best place to see in Europe.

The University of Modena and Reggio Emilia (Italian: Università degli Studi di Modena e Reggio Emilia), located in Modena and Reggio Emilia, Emilia-Romagna, Italy, is one of the oldest universities in Europe, founded in 1175, with a population of 20,000 students.

The medieval university disappeared by 1338 and was replaced by "three public lectureships" which did not award degrees and were suspended in the 1590s "for lack of money". The university was not reestablished in Modena until the 1680s and did not receive an imperial charter until 1685.

Castelfranco Emilia (Western Bolognese: Castèl; Modenese: Castèlfrànc) is a town and comune in Modena, Emilia-Romagna, north-central Italy. The town lies about 25 kilometres (16 mi) northwest of Bologna.

Castelfranco either occupies or lies near the site of the ancient Forum Gallorum, a place on the via Aemilia between Modena and Bologna. Near the town, on 14 April 43 BC, Octavian and Hirtius defeated Mark Antony in a battle during the War of Mutina. The village never gained prominence in ancient times. While it was included in the Tabula Peutingeriana, it was omitted from all other Roman road itineraries.

The Cantino planisphere or Cantino world map is a manuscript Portuguese world map preserved at the Biblioteca Estense in Modena, Italy. It is named after Alberto Cantino, an agent for the Duke of Ferrara, who successfully smuggled it from Portugal to Italy in 1502. It measures 220 x 105 cm.

The planisphere is the earliest surviving map showing Portuguese geographic discoveries in the east and west and is particularly notable for portraying a fragmentary record of the Brazilian coast, which the Portuguese explorer Pedro Álvares Cabral explored in 1500, the southern coast of Greenland, studied in the late 1490s, and the African coast of the Atlantic and Indian Oceans with remarkable accuracy and detail.

An elliptical dome, or an oval dome, is a dome whose bottom cross-section takes the form of an ellipse. Technically, an ellipsoidal dome has a circular cross-section, so is not quite the same.

While the cupola can take different geometries, when the ceiling's cross-section takes the form of an ellipse, and due to the reflecting properties of an ellipse, any two persons standing at a focus of the floor's ellipse can have one whisper, and the other hears; this is a whispering gallery.

The Battle of Forum Gallorum was fought on 14 April 43 BC between the forces of Mark Antony and legions loyal to the Roman Senate under the overall command of consul Gaius Pansa, aided by his fellow consul Aulus Hirtius. The untested Caesar Octavian (the future emperor Augustus) guarded the Senate's camp. The battle occurred on the Via Aemilia near a village in northern Italy, perhaps near modern-day Castelfranco Emilia.

Antony was attempting to capture the province of Cisalpine Gaul from its appointed governor, Decimus Brutus. Brutus was besieged by Antony in Mutina (modern Modena), just south of the Padus (Po) River on the Via Aemilia. The Roman Senate sent all its available forces to confront Antony and relieve Brutus. Hirtius and Octavian arrived near Mutina with five veteran legions, where they waited for Pansa, who was marching north from Rome with a further four legions of recruits. Antony had four veteran legions in addition to the troops that were besieging Mutina. Aware that he would soon be outnumbered, Antony sought to defeat his opponents in detail before they could link up. After failing to provoke a battle with Hirtius, Antony marched two of his legions between the two Senatorial armies and laid an ambush on Pansa's approaching recruits. Unknown to Antony, Pansa had already been joined by one of Hirtius' veteran legions and Octavian's praetorian cohorts.

The Battle of Mutina took place on 21 April 43 BC between the forces loyal to the Senate under consuls Gaius Vibius Pansa and Aulus Hirtius, supported by the forces of Caesar Octavian, versus the forces of Mark Antony which were besieging the troops of Decimus Brutus. The latter, one of Caesar's assassins, held the city of Mutina (present-day Modena) in Cisalpine Gaul.

Six days earlier, the Battle of Forum Gallorum had ended with heavy losses on both sides and the mortal wounding of consul Pansa. Hirtius and Octavian then launched an attack on Antony's camp, seeking to break the siege. Amid bloody fighting, Hirtius was killed, leaving the army and republic leaderless. Octavian saw action in the battle, recovered Hirtius' body, and managed to avoid defeat. Decimus Brutus also participated in the fighting with part of his forces locked up in the city. Command of Hirtius' legions then devolved to Caesar Octavian. Decimus Brutus, marginalized after the battle, soon fled Italy in the hopes of joining fellow assassins Marcus Junius Brutus and Gaius Cassius Longinus; he was, however, captured and executed en route.

The Apuani were one of the most formidable and powerful of the Ligurian tribes who lived in ancient north-western Italy, mentioned repeatedly by Livy. From the circumstances related by him, it appears that they were the most easterly of the Ligurian tribes, who inhabited the lofty group of mountains bordering on Etruria, and appear to have occupied the valleys of the Macra (modern Magra) and Ausar (modern Serchio). Although they extended eastwards along the chain of the Apennines to the frontiers of the Arretines and the territory of Mutina (modern Modena) and Bononia (modern Bologna), the upper valley of the Macra about Pontremoli, including the area later known as Lunigiana where the Tuscan towns of Aulla, Fivizzano, Fosdinovo, Villfranca and Pontremoli are now found, and the adjoining Upper Garfagnana and Ligurian districts of Sarzana and La Spezia were their center.

To oppose their inroads, the Romans generally made Pisae (modern Pisa) the headquarters of one of their armies, and from thence carried their arms into the heart of the mountains: but their successes seldom effected more than to compel the enemy to disperse and take refuge in their villages and mountain strongholds in which they were generally able to defy the Roman arms.

Reggio di Calabria (Sicilian: Riggiu; Calabrian Greek: Ρήγι, romanized: Rìji), commonly and officially referred to as Reggio Calabria, or simply Reggio by its inhabitants, is the largest city in Calabria as well as the seat of the Metropolitan City of Reggio Calabria.

The Modena Codex (Modena, Biblioteca Estense, α.m.5,24; often referred to with the siglum Mod A) is an early fifteenth-century Italian manuscript of medieval music. The manuscript is one of the most important sources of the ars subtilior style of music. It is held in the Biblioteca Estense library in Modena.

The precise origin of Mod A is controversial, with Pavia/Milan, Pisa and Bologna all being proposed. Firm evidence of ownership of the book by the Biblioteca Estense only occurs in the early nineteenth century, although a 1495 catalogue of the Este family library in Ferrara might refer to it. It was rediscovered by the philologist Antonio Cappelli in 1868.
