Roman senator in the context of "Senate of the Roman Kingdom"

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.

Egypt was established as a Roman province in consequence of the Battle of Actium, where Cleopatra as the last independent ruler of Egypt and her Roman ally Mark Antony were defeated by Octavian, the adopted heir of the assassinated Roman dictator Julius Caesar. Octavian then rose to supreme power with the title Augustus, ending the era of the Roman Republic and installing himself as princeps, the so-called "leading citizen" of Rome who in fact acted as an autocratic ruler. Although senators continued to serve as governors of most other provinces (the senatorial provinces), especially those annexed under the Republic, the role of Egypt during the civil war with Antony and its strategic and economic importance prompted Augustus to ensure that no rival could secure Aegyptus as an asset. He thus established Egypt as an imperial province, to be governed by a prefect he appointed from men of the equestrian order.

Lucius Julius Caesar (fl. 1st century BC) was a Roman politician and senator who was consul in 64 BC. A supporter of his cousin, the Roman dictator Gaius Julius Caesar, Lucius was a key member of the senatorial coalition which strove to avoid civil war between the Senate and his nephew Mark Antony in the aftermath of Caesar's assassination in 44 BC.

Lucius Antonius Saturninus was a Roman senator and general during the reign of Vespasian and his sons. While governor of the province called Germania Superior, motivated by a personal grudge against Emperor Domitian, he led a rebellion known as the Revolt of Saturninus, involving the legions Legio XIV Gemina and Legio XXI Rapax, camped in Moguntiacum (Mainz).

Lucius Junius Gallio Annaeanus or Gallio (Greek: Γαλλιων, Galliōn; c. 5 BC – c. AD 65) was a Roman senator and brother of the writer Seneca. He is best known for dismissing an accusation brought against Paul the Apostle in Corinth.

Gnaeus Octavius (died 87 BC) was a Roman senator who was elected consul of the Roman Republic in 87 BC alongside Lucius Cornelius Cinna. He died during the chaos that accompanied the capture of Rome by Cinna and Gaius Marius.

Pope Gregory I (Latin: Gregorius I; Gregorio I; c. 540 – 12 March 604), commonly known as Saint Gregory the Great (Latin: Sanctus Gregorius Magnus; Italian: San Gregorio Magno), was the 64th Bishop of Rome from 3 September 590 until his death on 12 March 604. He is known for instituting the first recorded large-scale mission from Rome, the Gregorian mission, to convert the then largely pagan Anglo-Saxons to Christianity. Gregory is also well known for his writings, which were more prolific than those of any of the previous popes. The epithet Saint Gregory the Dialogist has been attached to him in Eastern Christianity because of his Dialogues. English translations of Eastern texts sometimes list him as Gregory "Dialogos" from the Greek διάλογος (dialogos, conversation), or the Anglo-Latinate equivalent "Dialogus". He is the second of the three Popes listed in the Annuario Pontificio with the title "the Great", alongside Popes Leo I and Nicholas I.

A Roman senator's son, and himself the prefect of Rome at 30, Gregory lived in a monastery that he established on his family estate before becoming a papal ambassador and then pope. Before becoming Pope, he challenged the theological views of Patriarch Eutychius of Constantinople before the emperor Tiberius II. Although he was the first pope from a monastic background, his prior political experiences may have helped him to be a talented administrator. During his papacy, his administration greatly surpassed that of the emperors Maurice and Theodosius in improving the welfare of the people of Rome. Gregory regained papal authority in Spain and France and sent missionaries to England, including Augustine of Canterbury and Paulinus of York. The realignment of barbarian allegiance to Rome from their Arian Christian alliances shaped medieval Europe. Gregory saw Franks, Lombards, and Visigoths align with Rome in religion. He also combated the Donatist heresy, popular particularly in North Africa at the time.
