Quintus Caecilius Metellus Pius (c. 130 BC – 63 BC) was a pro-Sullan politician and general who was Roman consul in 80 BC. He was the principal Senatorial commander during the Sertorian War, fighting alongside Pompeius Magnus. He was given the agnomen (nickname) “Pius” because of his constant and unbending attempts to have his father officially recalled from exile.
Metellus Pius, a member of the distinguished plebeian gens Caecilia was the son of Quintus Caecilius Metellus Numidicus, who was consul in 109 BC. His career began in that same year, when he accompanied his father to Numidia as his contubernalis (cadet) during the Jugurthine War, returning to Rome in 107 BC, when his father was forcibly recalled by the actions of Gaius Marius. In 100 BC, after his father was banished as a result of the political manoeuvrings of Gaius Marius and Lucius Appuleius Saturninus, Metellus Pius launched a campaign to have his father brought back from exile. He produced a petition in 99 BC to this effect, and his constant pleading on the subject resulted in Quintus Calidius, the Plebeian Tribune of 98 BC passing a law which allowed his father to return. As a result of his fidelity, he was given the agnomen “Pius” for the constancy and inflexibility with which he fought for his father's political rehabilitation and return to Rome.
Sometime during 90s BC, Metellus Pius was elected to the College of Pontiffs as a result of his family's eminence and influence. The outbreak of the Social War saw him employed as a legate in late 89 BC, probably of the consul Pompeius Strabo, where he won some battles against the Marsi. As a result of these victories, he was elected Praetor in the following year (88 BC). During his praetorship, he was tasked with enrolling the Italian allies as new Roman citizens within sixty days, in accordance with the Lex Plautia Papiria. Once this was completed, Metellus Pius was again posted to the Social War, replacing Gaius Cosconius on the southern front. He harassed the territory around Apulia, captured the town of Venusia, and defeated the leading Italian leader, Quintus Poppaedius Silo, who died in the storming of Venusia.Cicero, at the time a young man, also remembered hearing Metellus speak at contiones in Rome during this period, most likely during his praetorship. Cicero remarked of Metellus' ability: 'although no real orator, he was nonetheless not without some capacity for public speech'.
