Constantine the Great [SEP] Early life
Flavius Valerius Constantinus, as he was originally named, was born in the city of Naissus, (today Niš, Serbia) part of the Dardania province of Moesia on 27 February, probably AD 272. His father was Flavius Constantius, an Illyrian, and a native of Dardania province of Moesia (later Dacia Ripensis). Constantine probably spent little time with his father who was an officer in the Roman army, part of the Emperor Aurelian's imperial bodyguard. Being described as a tolerant and politically skilled man, Constantius advanced through the ranks, earning the governorship of Dalmatia from Emperor Diocletian, another of Aurelian's companions from Illyricum, in 284 or 285.
