Emperor Diocletian

Year 284 (CCLXXXIV) was a leap year starting on Tuesday of the Julian calendar. At the time, it was known as the Year of the Consulship of Carinus and Numerianus (or, less frequently, year 1037 Ab urbe condita). The denomination 284 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.

Events

By place

Roman Empire

• Emperor Numerian travels through Bithynia (Asia Minor) on his way home to Rome. Suffering from an inflammation of the eyes, he travels in a closed litter in which soldiers find his decaying corpse.
• November 17 – Diocletian becomes emperor of Rome
• November 20 – The commander of Numerian's domestici (household troops), Diocles, is chosen to be the new emperor. In a military assembly outside Nicomedia (modern İzmit, Turkey), Diocles claims that the praetorian prefect (and rival for the throne) Arrius Aper murdered Numerian, and he personally stabs and kills the prefect on the spot. The new emperor changes his name to the Latinised 'Diocletian'. Building on existing trends, Diocletian presents his rule as that of a god-like dominus or autocrat.
• Sabinus Julianus, the praetorian prefect of Emperor Carinus, exploits the instability and usurps the throne in northern Italy.
