390

Year 390 (CCCXC) was a common year starting on Tuesday of the Julian calendar. At the time, it was known as the Year of the Consulship of Augustus and Neoterius (or, less frequently, year 1143 Ab urbe condita). The denomination 390 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.

April – Massacre of Thessalonica: Resentment among the citizens of Thessalonica (Macedonia) breaks out into violence after the arrest of a popular charioteer. Butheric, military commander of Illyricum, is murdered. Emperor Theodosius I orders vengeance, despite the pleas for mercy by Ambrose, bishop of Milan; more than 7,000 inhabitants are massacred by the Roman army.
