310
year
Year 310 (CCCX) was a common year starting on Sunday of the Julian calendar. At the time, it was known as the Year of the Consulship of Andronicus and Probus (or, less frequently, year 1063 Ab urbe condita). The denomination 310 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
Maximian, retired emperor, rebels against Constantine I in Arles while the latter is campaigning against the Franks.
Maximinus Daza, caesar under Emperor Galerius, is acclaimed augustus by his troops. Galerius is forced to recognize him as co-ruler of the East. The Roman Empire is thus divided between seven simultaneous emperors: Galerius (East), Maximinus II (East), Licinius (Middle), Constantine I (West), Maximian (West), Maxentius (Italy), and Domitius Alexander (Africa).
July – Maximian flees to Marseille where he is besieged and surrenders. Constantine encourages his suicide and Maximian, age 60, hangs himself. Emperor Maxentius condemns the killing of his father.
This brief starts where responsible research should: with the source description of “310” as year. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as year. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Apr 16, 2026. The linked authority identifier is Q32427. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1063.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
