Where was the Emperor born, under whom Rufrius Crispinus was commander of the Praetorian Guard ?
Claudius Claudius ( ; Latin: "Tiberius Claudius Caesar Augustus Germanicus" ; 1 August 10 BC – 13 October 54 AD) was Roman emperor from 41 to 54. A member of the Julio-Claudian dynasty, he was the son of Drusus and Antonia Minor. He was born at Lugdunum in Gaul, the first (and until Trajan, the only) Roman Emperor to be born outside Italy. Because he was afflicted with a limp and slight deafness due to sickness at a young age, his family ostracized him and excluded him from public office until his consulship, shared with his nephew Caligula in 37.
Constantine the Great Constantine the Great (Latin: "Flavius Valerius Aurelius Constantinus Augustus" ; Greek: Κωνσταντῖνος ὁ Μέγας ; 27 February 272 AD – 22 May 337 AD), also known as Constantine I or Saint Constantine (in the Orthodox Church as Saint Constantine the Great, Equal-to-the-Apostles), was a Roman Emperor of Illyrian-Greek origin from 306 to 337 AD. He was the son of Flavius Valerius Constantius, a Roman Army officer, and his consort Helena. His father became "Caesar", the deputy emperor in the west, in 293 AD. Constantine was sent east, where he rose through the ranks to become a military tribune under Emperors Diocletian and Galerius. In 305, Constantius raised himself to the rank of "Augustus", senior western emperor, and Constantine was recalled west to campaign under his father in Britannia (Britain). Constantine was acclaimed as emperor by the army at Eboracum (modern-day York) after his father's death in 306 AD, and he emerged victorious in a series of civil wars against Emperors Maxentius and Licinius to become sole ruler of both west and east by 324 AD.
