Mos maiorum

Social class in ancient Rome was hierarchical, with multiple and overlapping social hierarchies. An individual's relative position in one might be higher or lower than in another, which complicated the social composition of Rome.

Patronage (clientela) was the distinctive relationship in ancient Roman society between the patronus ("patron") and their cliens ("client"). The relationship was hierarchical, but obligations were mutual. The patron was the protector, sponsor, and benefactor of the client; the technical term for this protection was patrocinium. Although typically the client was of inferior social class, a patron and client might even hold the same social rank, but the former would possess greater wealth, power, or prestige that enabled him to help or do favors for the client. From the emperor at the top to the commoner at the bottom, the bonds between these groups found formal expression in legal definition of patrons' responsibilities to clients. Patronage relationship were not exclusively between two people and also existed between a general and his soldiers, a founder and colonists, and a conqueror and a dependent foreign community.

A Roman governor was an official either elected or appointed to be the chief administrator of Roman law throughout one or more of the many provinces constituting the Roman Empire.

The patricians were originally a group of ruling class families in ancient Rome. The distinction was highly significant in the Roman Kingdom, and the early Republic, but its relevance waned after the Conflict of the Orders. By the time of the late Republic and Empire, membership in the patriciate was of only nominal significance.

In ancient Rome, the plebeians were the general body of free Roman citizens who were not patricians, as determined by the census, or in other words "commoners". Both classes were hereditary.

The Conflict of the Orders, sometimes referred to as the Struggle of the Orders, was a political struggle between the plebeians (commoners) and patricians (aristocrats) of the ancient Roman Republic lasting from 500 BC to 287 BC in which the plebeians sought political equality with the patricians. It played a major role in the development of the Constitution of the Roman Republic. Shortly after the founding of the Republic, this conflict led to a secession from Rome by Plebeians to the Sacred Mount at a time of war. The result of this first secession was the creation of the office of plebeian tribune, and with it the first acquisition of real power by the plebeians.

The Roman Republic was a form of government of Rome and the era of the classical Roman civilization when it was run through public representation of the Roman people. Beginning with the overthrow of the Roman Kingdom and ending in 27 BC with the establishment of the Roman Empire, Rome's control rapidly expanded during this period—from the city's immediate surroundings to hegemony over the entire Mediterranean world.

Marcus Tullius Cicero was a Roman statesman, lawyer, scholar, philosopher, and academic skeptic, who tried to uphold optimate principles during the political crises that led to the establishment of the Roman Empire. His extensive writings include treatises on rhetoric, philosophy and politics. He is considered one of Rome's greatest orators and prose stylists. He came from a wealthy municipal family of the Roman equestrian order, and served as consul in 63 BC.

Quintus Aurelius Symmachus signo Eusebius was a Roman statesman, orator, and man of letters. He held the offices of governor of proconsular Africa in 373, urban prefect of Rome in 384 and 385, and consul in 391. Symmachus sought to preserve the traditional religions of Rome at a time when the aristocracy was converting to Christianity, and led an unsuccessful delegation of protest against Emperor Gratian's order to remove the Altar of Victory from the curia, the principal meeting place of the Roman Senate in the Forum Romanum. Two years later he made a famous appeal to Gratian's successor, Valentinian II, in a dispatch that was rebutted by Ambrose, the bishop of Milan. Symmachus's career was temporarily derailed when he supported the short-lived usurper Magnus Maximus, but he was rehabilitated and three years later appointed consul. After the death of Theodosius I, he became an ally of Stilicho, the guardian of emperor Honorius. In collaboration with Stilicho he was able to restore some of the legislative powers of the Senate. Much of his writing has survived: nine books of letters; a collection of Relationes or official dispatches; and fragments of various orations.

The fall of the Western Roman Empire was the loss of central political control in the Western Roman Empire, a process in which the Empire failed to enforce its rule, and its vast territory was divided into several successor polities. The Roman Empire lost the strengths that had allowed it to exercise effective control over its Western provinces; modern historians posit factors including the effectiveness and numbers of the army, the health and numbers of the Roman population, the strength of the economy, the competence of the emperors, the internal struggles for power, the religious changes of the period, and the efficiency of the civil administration. Increasing pressure from invading barbarians outside Roman culture also contributed greatly to the collapse. Climatic changes and both endemic and epidemic disease drove many of these immediate factors. The reasons for the collapse are major subjects of the historiography of the ancient world and they inform much modern discourse on state failure.

The barbarian kingdoms, also known as the post-Roman kingdoms, the western kingdoms or the early medieval kingdoms, were the states founded by various non-Roman, primarily Germanic, peoples in Western Europe and North Africa following the collapse of the Western Roman Empire in the fifth century. The formation of the barbarian kingdoms was a complicated, gradual and largely unintentional process, as the Roman state failed to handle barbarian migrants on the imperial borders, leading to both invasions and invitations into imperial territory, but simultaneously denied barbarians the ability to properly integrate into the imperial framework. The influence of barbarian rulers, at first local warlords and client kings without firm connections to any territories, increased as Roman emperors and usurpers used them as pawns in civil wars. It was only after the collapse of effective Western Roman central authority that the barbarian realms transitioned into proper territorial kingdoms.

The Germanic peoples were historical groups of people that once occupied Central Europe and Scandinavia during antiquity and into the early Middle Ages. Since the 19th century, they have traditionally been defined by the use of ancient and early medieval Germanic languages and are thus equated at least approximately with Germanic-speaking peoples, although different academic disciplines have their own definitions of what makes someone or something "Germanic". The Romans named the area belonging to North-Central Europe in which Germanic peoples lived Germania, stretching East to West between the Vistula and Rhine rivers and north to south from Southern Scandinavia to the upper Danube. In discussions of the Roman period, the Germanic peoples are sometimes referred to as Germani or ancient Germans, although many scholars consider the second term problematic since it suggests identity with present-day Germans. The very concept of "Germanic peoples" has become the subject of controversy among contemporary scholars. Some scholars call for its total abandonment as a modern construct since lumping "Germanic peoples" together implies a common group identity for which there is little evidence. Other scholars have defended the term's continued use and argue that a common Germanic language allows one to speak of "Germanic peoples", regardless of whether these ancient and medieval peoples saw themselves as having a common identity.

Feudalism, also known as the feudal system, is a term used to describe the legal, economic, military, cultural and political customs that flourished in medieval Europe between the 9th and 15th centuries. Broadly defined, it was a way of structuring society around relationships that were derived from the holding of land in exchange for service or labour. Although it is derived from the Latin word feodum or feudum (fief), which was used during the Medieval period, the term feudalism and the system which it describes were not conceived of as a formal political system by the people who lived during the Middle Ages. The classic definition, by François Louis Ganshof (1944), describes a set of reciprocal legal and military obligations which existed among the warrior nobility and revolved around the three key concepts of lords, vassals, and fiefs.

Roman law is the legal system of ancient Rome, including the legal developments spanning over a thousand years of jurisprudence, from the Twelve Tables, to the Corpus Juris Civilis ordered by Eastern Roman emperor Justinian I. Roman law forms the basic framework for civil law, the most widely used legal system today, and the terms are sometimes used synonymously. The historical importance of Roman law is reflected by the continued use of Latin legal terminology in many legal systems influenced by it, including common law.

Personification is the representation of a thing or abstraction as a person. In the arts, many things are commonly personified. These include numerous types of places, especially cities, countries, and continents, elements of the natural world such as the months or four seasons, four elements, four cardinal winds, five senses, and abstractions such as virtues, especially the four cardinal virtues and seven deadly sins, the nine Muses, or death.

The Capitolium or Capitoline Hill, between the Forum and the Campus Martius, is one of the Seven Hills of Rome.

In Greco-Roman mythology, Aeneas was a Trojan hero, the son of the Dardanian prince Anchises and the Greek goddess Aphrodite. His father was a first cousin of King Priam of Troy, making Aeneas a second cousin to Priam's children. He is a minor character in Greek mythology and is mentioned in Homer's Iliad. Aeneas receives full treatment in Roman mythology, most extensively in Virgil's Aeneid, where he is cast as an ancestor of Romulus and Remus. He became the first true hero of Rome. Snorri Sturluson identifies him with the Norse god Vidarr of the Æsir.

The Aeneid is a Latin epic poem, written by Virgil between 29 and 19 BC, that tells the legendary story of Aeneas, a Trojan who fled the fall of Troy and travelled to Italy, where he became the ancestor of the Romans. It comprises 9,896 lines in dactylic hexameter. The first six of the poem's twelve books tell the story of Aeneas' wanderings from Troy to Italy, and the poem's second half tells of the Trojans' ultimately victorious war upon the Latins, under whose name Aeneas and his Trojan followers are destined to be subsumed.

The Latin term religiō, the origin of the modern lexeme religion, is of ultimately obscure etymology. It is recorded beginning in the 1st century BC, i.e. in Classical Latin at the end of the Roman Republic, notably by Cicero, in the sense of "scrupulous or strict observance of the traditional cultus". In classic antiquity, it meant conscientiousness, sense of right, moral obligation, or duty towards anything and was used mostly in secular or mundane contexts.

Religion in ancient Rome consisted of varying imperial and provincial religious practices, which were followed both by the people of Rome as well as those who were brought under its rule.

Gaius Mucius Cordus, better known with his later cognomen Scaevola, was an ancient Roman youth, possibly mythical, famous for his bravery.
