History of Rome in the context of "Auctoritas"

Rome is the capital city and most populated comune (municipality) of Italy. It is also the administrative centre of the Lazio region and of the Metropolitan City of Rome. A special comune named Roma Capitale with 2,746,984 residents in 1,287.36 km (497.1 sq mi), Rome is the third most populous city in the European Union by population within city limits. The Metropolitan City of Rome Capital, with a population of 4,223,885 residents, is the most populous metropolitan city in Italy. Its metropolitan area is the third-most populous within Italy. Rome is located in the central-western portion of the Italian Peninsula, within Lazio (Latium), along the shores of the Tiber Valley. Vatican City (the smallest country in the world and headquarters of the worldwide Catholic Church under the governance of the Holy See) is an independent country inside the city boundaries of Rome, the only existing example of a country within a city. Rome is often referred to as the City of Seven Hills due to its geography, and also as the "Eternal City". Rome is generally considered to be one of the cradles of Western civilization and Western Christian culture, and the centre of the Catholic Church.

Rome's history spans 28 centuries. While Roman mythology dates the founding of Rome at around 753 BC, the site has been inhabited for much longer, making it a major human settlement for over three millennia and one of the oldest continuously occupied cities in Europe. The city's early population originated from a mix of Latins, Etruscans, and Sabines. Eventually, the city successively became the capital of the Roman Kingdom, the Roman Republic and the Roman Empire, and is regarded by many as the first-ever Imperial city and metropolis. It was first called The Eternal City (Latin: Urbs Aeterna; Italian: La Città Eterna) by the Roman poet Tibullus in the 1st century BC, and the expression was also taken up by Ovid, Virgil, and Livy. Rome is also called Caput Mundi (Capital of the World).

Marcus Porcius Cato (/ˈkɑːtoʊ/, KAH-toe; 234–149 BC), also known as Cato the Censor (Latin: Censorius), the Elder and the Wise, was a Roman soldier, senator, and historian known for his conservatism and opposition to Hellenization. He was the first to write history in Latin with his Origines, a now fragmentary work on the history of Rome. His work De agri cultura, a treatise on agriculture, rituals, and recipes, is the oldest extant prose written in the Latin language. His epithet "Elder" distinguishes him from his great-grandson Senator Cato the Younger, who opposed Julius Caesar.

He came from an ancient plebeian family who were noted for their military service. Like his forefathers, Cato was devoted to agriculture when not serving in the army. Having attracted the attention of Lucius Valerius Flaccus, he was brought to Rome. He was successively military tribune (214 BC), quaestor (204), aedile (199), praetor (198), consul (195) together with Flaccus, and censor (184). As praetor, he expelled usurers from Sardinia. As censor, he tried to save Rome's ancestral customs and combat Hellenistic influences.

In Roman mythology, Romulus and Remus (Latin: [ˈroːmʊlʊs], [ˈrɛmʊs]) are twin brothers whose story tells of the events that led to the founding of the city of Rome and the Roman Kingdom by Romulus, following his fratricide of Remus. The image of a she-wolf suckling the twins in their infancy has been a symbol of the city of Rome and the ancient Romans since at least the 3rd century BC. Although the tale takes place before the founding of Rome in 753 BC, the earliest known written account of the myth is from the late 3rd century BC. Possible historical bases for the story, and interpretations of its local variants, are subjects of ongoing debate.

The Capitoline Museums (Italian: Musei Capitolini) are a group of art and archaeological museums located on the Capitoline Hill in Rome, Italy. Their principal buildings are the Palazzo dei Conservatori and the Palazzo Nuovo, which face each other across Piazza del Campidoglio, the square designed by Michelangelo in 1536 and completed over the course of the following centuries.

The museums are primarily dedicated to the art and history of ancient Rome, with a particular emphasis on Roman sculpture. The collection include celebrated works such as the Equestrian Statue of Marcus Aurelius, the Capitoline Wolf and the Dying Gaul, alongside inscriptions, coins, and other artifacts illustrating the civic and religious life of the city. The museums also include Renaissance and Baroque paintings, as well as the richly frescoed walls of the Conservators' Apartment in the Palazzo dei Conservatori, which depict scenes from Rome's early history.

The Crisis of the Third Century, also known as the Military Anarchy or the Imperial Crisis, was a period in Roman history during which the Roman Empire nearly collapsed under the combined pressure of repeated foreign invasions, civil wars and economic disintegration. At the height of the crisis, the Roman state split into three distinct and competing polities. The period is usually dated between the death of Severus Alexander (235) and accession of Diocletian (284).

The crisis began in 235 with the assassination of Emperor Severus Alexander by his own troops. During the following years, the empire saw barbarian invasions and migrations into Roman territory, civil wars, peasant rebellions and political instability, with multiple usurpers competing for power. This led to the debasement of currency and a breakdown in both trade networks and economic productivity, with the Plague of Cyprian contributing to the disorder. Roman armies became more reliant over time on the growing influence of the barbarian mercenaries known as foederati. Roman commanders in the field, although nominally loyal to the state, became increasingly independent of Rome's central authority.

Ostia Antica (lit. 'Ancient Ostia') is an ancient Roman city and the port of Rome located at the mouth of the Tiber. It is near modern Ostia, 25 km (16 mi) southwest of Rome. Due to silting and the invasion of sand, the site now lies 3 km (2 mi) from the sea. The name Ostia (the plural of ostium) derives from Latin os 'mouth'.

Ostia is now a large archaeological site noted for the excellent preservation of its ancient buildings, magnificent frescoes and impressive mosaics. The city's decline after antiquity led to harbor deterioration, marshy conditions, and reduced population. Sand dunes covering the site aided its preservation. Its remains provide insights into a city of commercial importance. As in Pompeii, Ostia's ruins provide details about Roman urbanism that are not accessible within the city of Rome itself.

Regillus was an ancient lake of Latium, Italy, famous in the legendary history of Rome as the lake near which the Battle of Lake Regillus took place in 496 B.C. between the Romans and the Latins which finally decided the hegemony of Rome in Latium. The lake, now drained, was near the present-day town of Frascati.

During the battle, so the story runs, the Roman dictator Postumius vowed to build a temple to the twin gods Castor and Pollux, who were specially venerated in Tusculum, the chief city of the Latins (it being a Roman custom to invoke the aid of the gods of the enemy). The pair duly appeared during the battle dressed in white armour riding white horses, helped the Romans to prevail, and afterwards took the news of the victory to Rome. There they watered their horses at the spring of Juturna, close to which their temple in the Forum was subsequently erected.
