Year 390 BC was a year of the pre-Julian Roman calendar. At the time, it was known as the Year of the Tribunate of Ambustus, Longus, Ambustus, Fidenas, Ambustus and Cornelius (or, less frequently, year 364 Ab urbe condita). The denomination 390 BC 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 Republic

• July 18 – Battle of the Allia: Brennus, a chieftain of the Senones of the Adriatic coast of Italy, leads an army of Cisalpine Gauls in their attack on Rome. They capture the entire city of Rome except for the Capitoline Hill, which is successfully held against them. However, seeing their city devastated, the Romans attempt to buy their salvation from Brennus. The Romans agree to pay one thousand pounds weight of gold.
• While Brennus is arguing over the weight of the gold with the Romans, the exiled dictator Marcus Furius Camillus appears with an army and refuses to allow him to take the gold. In an initial battle through Rome's streets, the Gauls are ejected from the city and in a second battle away from the city, Camillus defeats the invaders, earning the title of the "Second Founder of Rome" for saving the city.
