Magnus Magnentius

Year 350 (CCCL) was a common year starting on Monday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Sergius and Nigrinianus (or, less frequently, year 1103 Ab urbe condita). The denomination 350 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.


By place[edit]

Roman Empire[edit]

  • January 18 – Western Roman Emperor Constans I makes himself extremely unpopular; one of his generals, Magnentius, is proclaimed emperor at Augustodunum in the Diocese of Galliae, with the support of the army on the Rhine frontier.
  • January – Constans I flees towards Spain, where he is subsequently assassinated at Castrum Helenae. Magnentius rules the Western portion of the Roman Empire and is far more tolerant towards Christians and Pagans alike.
  • March 1Vetranio is asked by Constantina, sister of Constantius II, to proclaim himself Caesar. Constantius accepts the new emperor and sends him funds to raise an army.
  • June 3Nepotianus, Roman usurper, proclaims himself emperor and enters Rome with a group of gladiators.[1]
  • June 30 – Nepotianus is defeated and killed by Marcellinus, a trusted general sent by Magnentius. His head is put on a spear and carried around the city.
  • December 25 – Vetranio meets Constantius II at Naissus (Serbia) and joins forces with him. Vetranio is forced to abdicate his title, and Constantius allows him to live as a private citizen on a state pension.
