375
year
Year 375 (CCCLXXV) was a common year starting on Thursday of the Julian calendar. At the time, it was known in Rome as the Year after the Consulship of Augustus and Equitius (or, less frequently, year 1128 Ab urbe condita). The denomination 375 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.

Roman Empire
November 17 – Emperor Valentinian I concludes an enduring peace with the Alamanni in Germany, then marches into Illyricum to repel an invasion of the Quadi and the Sarmatians on the Danube frontier. While negotiating with the Quadi, Valentinian, age 54, becomes so enraged that he dies in a fit of apoplexy at Brigetio (Hungary). Extreme cruelty has marked his 11-year reign, but he has also founded schools and provided physicians to serve the poor of Constantinople.
The Quadi accept an uneasy peace from Merobaudes (Magister militum), which gives them land to settle on the Danube.
Gratian, age 16, takes over the government at Augusta Treverorum (modern Trier), but ministers wishing to retain the loyalty of the Illyrian army fear a usurper. They proclaim Valentinian's 4-year-old son Valentinian II co-emperor with his mother, Justina, as regent. Gratian reserves for himself the administration of the Gallic provinces, and hands over Italy, Illyrium, Hispania and Africa to his stepmother, who makes Mediolanum (Milan) her residence.
The public source identifies “375” as year. This brief keeps that definition visible, then builds a research path around year.
Why this record matters
A short description can identify a subject without explaining its stakes. For “375”, the useful work is to connect “year” to the records capable of establishing context and consequence.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Apr 16, 2026. The linked authority identifier is Q34902. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1128.
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.
