274
Year 274 was a common year starting on Thursday of the Julian calendar. At the time, it was known as the Year of the Consulship of Aurelianus and Capitolinus. The denomination 274 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
- Battle of Châlons: The Emperor Aurelian invades Gaul to campaign against the Gallic Empire. In the Catalaunian Plains, the Romano-Gallic Emperor Tetricus I surrenders to Aurelian and leaves his army without an emperor. The Gallic army is then crushed by Aurelian in a major battle. With the conquests of the Palmyrene Empire and the Gallic Empire, the Roman Empire is united again. However, the heavy losses incurred by the Gallic forces compromises the Rhine frontier.
- Rome greets Aurelian as Restitutor Orbis and accords him a magnificent triumph, which is graced by his captives Zenobia, Tetricus I, and his son Tetricus II.
- Aurelian reforms the Roman currency, replacing the denarius with a new version of the antoninianus that has a slightly improved silver-to-copper ratio. This overhaul of the currency system causes hyper-inflation.
- Germanic tribes take advantage of the destroyed Roman forces of the Rhine to raid Gaul.
- December 25 - Aurelian has the Temple of the Sun dedicated to Sol Invictus, on the third day after the solstice and day of rebirth of the sun. This religion, which is in essence monotheistic, becomes the state religion of Rome.
Africa
- The Kingdom of Aksum attains great prosperity thanks to its control of Red Sea trade.
