Titus Labienus

Titus Labienus (c. 100 BC – March 17, 45 BC) was a professional Roman soldier in the late Roman Republic. He served as Tribune of the Plebs in 63 BC, and is remembered as one of Julius Caesar's lieutenants, mentioned frequently in the accounts of his military campaigns. He was the father of Quintus Labienus.

Reasoning from the fact that his praetorship was in 60 or 59 BC, Titus Labienus most likely was born in 99 or 98 BC. Many sources suggest that he came from the town of Cingulum in Picenum. His family was of equestrian status. He most likely had early ties with Pompey during his time as a patron for Picenum and his desire to rise in military rank. His early service was c. 78–75 BC in Cilicia under Publius Servilius Vatia Isauricus.

In 63 BC, Titus Labienus was a Tribune of the Plebs with close ties to Pompey. Gaius Julius Caesar was also working closely with Pompey and therefore he and Labienus occasionally cooperated. These interactions were the seed that eventually developed into a friendship between Labienus and Caesar.

At Caesar's instigation, Labienus accused Gaius Rabirius of high treason (perduellio) for the murder of the tribune Lucius Appuleius Saturninus and of his uncle Titus Labienus in 100 BC. The purpose of this trial was to discredit the so-called "final decree of the Senate" (senatus consultum ultimum), an emergency measure of the senate commonly used against the Populares and the Roman assemblies. Labienus used the antiquated procedure of the duumviri, used in the early republic, against Rabirius. The procedure bypassed normal criminal law and Rabirius would be tried without defense. Since tribunes were , it was seen as an act against the gods to kill one. Thus punishment of the culprit was seen as more of a cleansing to appease the gods. The killing was seen as a pollution so profound that a normal criminal trial was unnecessary and immediate cleansing was necessary to avoid the wrath of the gods. The duumviri were assigned to accuse under the pretense of obvious guilt and cleanse the culprit through scourging.
