Brother of Quintus Minucius Esquilinus Augurinus, consul in 457 BC, he was a member of the Minucii Augurini branch of the gens Minucia.
[4][3] Once back in Rome, Augurinus abdicated and command of his army was given to the praefectus Urbi, Quintus Fabius Vibulanus.
This commission achieved the writing of the Law of the Twelve Tables, but under the influence of Crassus, they despotically maintained power after the end of their mission.
Quintus Fabius Vibulanus, Manius Rabuleius, and Quintus Poetelius Libo met the Sabines in battle while Lucius Minucius accompanied Marcus Cornelius Maluginensis, Lucius Sergius Esquilinus, and Titus Antonius Merenda in their fight with the Aequi.
[14] The example of Manius Marcius was soon followed by Spurius Maelius, a rich member of the Equestrian order, who had acquired great quantities of fresh wheat in Etruria, and then distributed it to the people for free.
[15] According to ancient authors, Lucius Minucius was rewarded with the erection of a statue for having alerted the patricians to the danger that Spurius Maelius posed.
