Year 313 (CCCXIII) was a common year starting on Thursday of the Julian calendar. At the time, it was known as the Year of the Consulship of Constantinus and Licinianus (or, less frequently, year 1066 Ab urbe condita). The denomination 313 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years. This year is notable for ending of the persecution of Christians in the Roman Empire.
Events
By place
Roman Empire
- At the end of 312 or in early 313, the retired Emperor Diocletian dies in his palace in Split, most likely from natural causes.
- February: Emperors Constantine I and Licinius convene in Mediolanum (modern Milan). Licinius marries Constantine's half-sister Constantia, and they issue the Edict of Milan. This edict ends the Great Persecution against the Christians and is the first piece of legislation in western history to decree freedom of religion. It also returns property confiscated from Christians.[1] The edict is posted in Nicomedia on June 13.
- Emperor Maximinus Daza crosses the Bosphorus with an army of 70,000 men and lays siege to Heraclea in Thrace. He captures the city after eight days.
- Battle of Tzirallum: Licinius defeats his rival Maximinus in Thrace, who then flees to Cilicia. After losing the Cilician Gates to Licinius' forces, Maximinus commits suicide.
- Licinius conducts a purge of the wider Tetrarchic dynasty. He executes Galerius' son Candidianus, Valerius Severus' son Severianus (whom he accuses of conspiracy), and Maximinus' wife, son and daughter. Diocletian's wife Prisca and daughter Galeria Valeria go into hiding.
