Roman governor

The Auxilia were introduced as non-citizen troops attached to the citizen legions by Augustus after his reorganisation of the Imperial Roman army from 27 BC. By the 2nd century, the Auxilia contained the same number of infantry as the legions and, in addition, provided almost all of the Roman army's cavalry and more specialised troops. The auxilia thus represented three-fifths of Rome's regular land forces at that time. Like their legionary counterparts, auxiliary recruits were mostly volunteers, not conscripts.

The Roman Senate was a governing and advisory assembly in ancient Rome. It was one of the most enduring institutions in Roman history, being established in the first days of the city of Rome. It survived the overthrow of the Roman monarchy in 509 BC; the fall of the Roman Republic in the 1st century BC; the division of the Roman Empire in AD 395; and the fall of the Western Roman Empire in 476; Justinian's attempted reconquest of the west in the 6th century, and lasted well into the Eastern Roman Empire's history.

A quaestor was a public official in Ancient Rome. There were various types of quaestors, with the title used to describe greatly different offices at different times.

Prefect is a magisterial title of varying definition, but essentially refers to the leader of an administrative area.

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.

In ancient Rome a promagistrate was a person who was granted the power via prorogation to act in place of an ordinary magistrate in the field. This was normally pro consule or pro praetore, that is, in place of a consul or praetor, respectively. This was expedient developed, starting in 327 BC and becoming regular by 241 BC, that was meant to allow consuls and praetors to continue their activities in the field without disruption.

A senatus consultum is a text emanating from the senate in Ancient Rome. It is used in the modern phrase senatus consultum ultimum.

The Roman Assemblies were institutions in ancient Rome. They functioned as the machinery of the Roman legislative branch, and thus passed all legislation. Since the assemblies operated on the basis of a direct democracy, ordinary citizens, and not elected representatives, would cast all ballots. The assemblies were subject to strong checks on their power by the executive branch and by the Roman Senate. Laws were passed by Curia, Tribes, and century.

Praetor, also pretor, was the title granted by the government of Ancient Rome to a man acting in one of two official capacities: (i) the commander of an army, and (ii) as an elected magistratus (magistrate), assigned to discharge various duties. The functions of the magistracy, the praetura (praetorship), are described by the adjective: the praetoria potestas, the praetorium imperium, and the praetorium ius, the legal precedents established by the praetores (praetors). Praetorium, as a substantive, denoted the location from which the praetor exercised his authority, either the headquarters of his castra, the courthouse (tribunal) of his judiciary, or the city hall of his provincial governorship.

A proconsul was an official of ancient Rome who acted on behalf of a consul. A proconsul was typically a former consul. The term is also used in recent history for officials with delegated authority.

A consul held the highest elected political office of the Roman Republic, and ancient Romans considered the consulship the second-highest level of the cursus honorum after that of the censor. Each year, the Centuriate Assembly elected two consuls to serve jointly for a one-year term. The consuls alternated in holding fasces – taking turns leading – each month when both were in Rome. A consul's imperium extended over Rome and all its provinces.

A lictor was a Roman civil servant who was an attendant and bodyguard to a magistrate who held imperium. Lictors are documented since the Roman Kingdom, and may have originated with the Etruscans.

Caesar Augustus, also known as Octavian, was the first Roman emperor; he reigned from 27 BC until his death in AD 14. He is known for being the founder of the Roman Principate, which is the first phase of the Roman Empire, and is considered one of the greatest leaders in human history. The reign of Augustus initiated an imperial cult as well as an era associated with imperial peace, the Pax Romana or Pax Augusta. The Roman world was largely free from large-scale conflict for more than two centuries despite continuous wars of imperial expansion on the empire's frontiers and the year-long civil war known as the "Year of the Four Emperors" over the imperial succession.

The Principate is the name sometimes given to the first period of the Roman Empire from the beginning of the reign of Augustus in 27 BC to the end of the Crisis of the Third Century in AD 284, after which it evolved into the so-called Dominate.

An imperial province was a Roman province during the Principate where the Roman Emperor had the sole right to appoint the governor. These provinces were often the strategically located border provinces.

A legatus Augusti pro praetore was the official title of the governor or general of some Imperial provinces of the Roman Empire during the Principate era, normally the larger ones or those where legions were based. Provinces were denoted imperial if their governor was selected by the emperor, in contrast to senatorial provinces, whose governors were elected by the Roman Senate.

Africa was a Roman province on the northern African coast that was established in 146 BC following the defeat of Carthage in the Third Punic War. It roughly comprised the territory of present-day Tunisia, the northeast of Algeria, and the coast of western Libya along the Gulf of Sirte. The territory was originally inhabited by Berber people, known in Latin as Mauri indigenous to all of North Africa west of Egypt; in the 9th century BC, Phoenicians built settlements along the Mediterranean Sea to facilitate shipping, of which Carthage rose to dominance in the 8th century BC until its conquest by the Roman Republic.

The Asia was a Roman province covering most of western Anatolia, which was created following the Roman Republic's annexation of the Attalid Kingdom in 133 BC. After the establishment of the Roman Empire by Augustus, it was the most prestigious senatorial province and was governed by a proconsul. That arrangement endured until the province was subdivided in the fourth century AD.

Egypt was a subdivision of the Roman Empire from Rome's invasion of the Ptolemaic Egyptian Kingdom after the battle of Alexandria in 30 BC to its loss by the Byzantine Empire to the Islamic conquests in AD 641. The province encompassed most of modern-day Egypt except for the Sinai, and was bordered by the provinces of Crete and Cyrenaica to the west and Judea, later Arabia Petraea, to the East. Egypt came to serve as a major producer of grain for the empire and had a highly developed urban economy. Aegyptus was by far the wealthiest Eastern Roman province, and by far the wealthiest Roman province outside of Italy. The population of Roman Egypt is unknown, although estimates vary from 4 to 8 million. Alexandria, its capital, was the largest port and second largest city of the Roman Empire.

During the Roman Empire, the governor of Roman Egypt (praefectus Aegypti) was a prefect who administered the Roman province of Egypt with the delegated authority (imperium) of the emperor.

Tiberius Claudius Caesar Augustus Germanicus was the fourth Roman emperor, ruling from AD 41 to 54. A member of the Julio-Claudian dynasty, Claudius was born to Drusus and Antonia Minor at Lugdunum in Roman Gaul, where his father was stationed as a military legate. He was the first Roman emperor to be born outside Italy. Nonetheless, Claudius was an Italian of Sabine origins.

The Dominate, also known as the late Roman Empire, is the name sometimes given to the "despotic" later phase of imperial government in the ancient Roman Empire. It followed the earlier period known as the "Principate". Until the empire was reunited in 313, this phase is more often called the Tetrarchy.

Diocletian, nicknamed "Jovius", was Roman emperor from 284 until his abdication in 305. He was born Diocles to a family of low status in the Roman province of Dalmatia. Diocles rose through the ranks of the military early in his career, eventually becoming a cavalry commander for the army of Emperor Carus. After the deaths of Carus and his son Numerian on a campaign in Persia, Diocles was proclaimed emperor by the troops, taking the name Diocletianus. The title was also claimed by Carus's surviving son, Carinus, but Diocletian defeated him in the Battle of the Margus.

Constantine I, also known as Constantine the Great, was Roman emperor from AD 306 to 337, the first one to convert to Christianity. Born in Naissus, Dacia Mediterranea, he was the son of Flavius Constantius, a Roman army officer of Illyrian origin who had been one of the four rulers of the Tetrarchy. His mother, Helena, was a Greek Christian of low birth. Later canonized as a saint, she is traditionally attributed with the conversion of her son. Constantine served with distinction under the Roman emperors Diocletian and Galerius. He began his career by campaigning in the eastern provinces before being recalled in the west to fight alongside his father in Britain. After his father's death in 306, Constantine became emperor. He was acclaimed by his army at Eboracum, and eventually emerged victorious in the civil wars against emperors Maxentius and Licinius to become the sole ruler of the Roman Empire by 324.

Augustus was an ancient Roman title given as both name and title to Gaius Julius Caesar Octavianus, Rome's first Emperor. On his death, it became an official title of his successor, and was so used by Roman emperors thereafter. The feminine form Augusta was used for Roman empresses and other female members of the Imperial family. The masculine and feminine forms originated in the time of the Roman Republic, in connection with things considered divine or sacred in traditional Roman religion. Their use as titles for major and minor Roman deities of the Empire associated the Imperial system and Imperial family with traditional Roman virtues and the divine will, and may be considered a feature of the Roman Imperial cult.

Caesar is a title of imperial character. It derives from the cognomen of Julius Caesar, a Roman dictator. The change from being a familial name to a title adopted by the Roman emperors can be traced to AD 68, following the fall of the Julio–Claudian dynasty.

A corrector is a person or object practicing correction, usually by removing or rectifying errors.

Dux is Latin for "leader" and later for duke and its variant forms. During the Roman Republic and for the first centuries of the Roman Empire, dux could refer to anyone who commanded troops, both Roman generals and foreign leaders, but was not a formal military rank.

Magister militum was a top-level military command used in the later Roman Empire, dating from the reign of Constantine the Great. The term referred to the senior military officer of the empire. In Greek sources, the term is translated either as strategos or as stratelates.

Flavius Julius Constans, sometimes called Constans I, was Roman emperor from 337 to 350. He held the imperial rank of caesar from 333, and was the youngest son of Constantine the Great.
