QUINTUS FABIUS AMBUSTUS (TRIBUNE)

'Quintus Fabius Ambustus' (flourished early 4th century BCE) was a politician in the Roman Republic, the son of Marcus Fabius Ambustus. In 390 BCE, when his father was pontifex maximus, he and two of his brothers, Numerius and Caeso, were sent as emissaries to a Gaulish army besieging Clusium. Instead of entering into negotiations, however, the three Fabii gathered their forces and aided the citizens of Clusium in a sally against the Gauls. Quintus Fabius himself killed one of the Gaulish leaders.
Outraged, the Gauls demanded that the senate hand over the three brothers for violating "the law of nations". Instead, all three were honoured by election as consular tribunes. Further incensed, the Gauls marched on Rome, defeated the Roman Army at the battle of the Allia, and sacked the city.
