According to Livy, Quintus was the only male to escape the slaughter of the gens Fabia at the Battle of the Cremera in 477 BC, since he was too young to be sent to war.
[1] He was consul of the Roman Republic three times: In his first consulship there was popular agitation for an agrarian law, which had been the cause of much social conflict at Rome for many years.
Fabius successfully brought an end to the conflict by passing a law that the lands of the Volsci at the new Roman colony of Antium be distributed amongst the plebs.
Three commissioners were named for the purpose of dividing the lands Titus Quintius, Aulus Verginius, and Publius Furius.
[15][16][17] In 450 BC, Appius Claudius named him one of the second set of decemviri, ten men given absolute authority in Rome while they compiled the Law of the Twelve Tables.
