Publius Decius Mus (consul 312 BC)

Publius Decius Mus (died 295 BC), of the plebeian gens Decia, was a Roman consul in the years 312 BC, 308 BC, 297 BC and 295 BC. He was a member of a family that was renowned for sacrificing themselves on the battlefield for Rome.

Publius Decius Mus, born the son of the consul of 340 BC Publius Decius Mus, was elected consul in 312 BC together with Marcus Valerius Maximus Corvinus. When war broke out with the Samnites, Mus had to stay in Rome due to an illness and it was his colleague who was sent to manage the war. When the Etruscans joined in the war on the side of Rome's enemies, Mus was ordered by the Senate to appoint a dictator.

In 309 BC he served as a legate under the dictator Lucius Papirius Cursor and the next year he was elected consul again, this time with Quintus Fabius Maximus Rullianus as his colleague. While his colleague handled the war against Samnium, Mus was entrusted with the war against the Etruscans in which he was so successful that the Etruscans sued for a truce.

In 306 BC Mus was appointed as the Master of the Horse to the dictator Publius Cornelius Scipio Barbatus. In 304 BC, Mus and Rullianus were elected censor. In 300 BC Mus successfully espoused the cause of opening the pontificate to the plebeians against Appius Claudius Caecus.

In 297 BC Mus and Rullianus were again elected consul. This time both consuls were to go to Samnium to make war. In this campaign Mus was able to defeat a Samnite army near Maleventum. The next year saw his command in Samnium prorogued as proconsul.
