Aureus of Postumus, within a pendant

Year 265 (CCLXV) was a common year starting on Sunday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Valerianus and Lucillus (or, less frequently, year 1018 Ab urbe condita). The denomination 265 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]

  • Emperor Gallienus tries twice to crush the usurper Postumus, but on the first occasion Aureolus, commander of the elite cavalry, carelessly lets him escape. The second time, Gallienus sustains an arrow wound and has to break off his siege of a Gallic town where Postumus has holed up. He makes no other serious attempt to overcome his rival, devotes his attention to the political and military problems in the Danube and eastern parts of the Roman Empire.
  • Postumus makes no move to march on Rome and claim his territory south of Gaul.
  • Gallienus gives the order to fortify Milan and Verona.
  • Gallienus repels the invasion of the Goths in the Balkans.
  • A general of Gallienus' army, Victorinus, defects to Postumus.
