Gnaeus Pompeius of Pompeia became a member of the First Triumvirate along with this general and politician who played a key role in the transformation of the Roman Republic into the Roman Empire and was the second wealthiest person next to which person?
Pompeia (gens) The gens Pompeia was a plebeian family at ancient Rome, first appearing in history during the second century BC, and frequently occupying the highest offices of the Roman state from then until imperial times. The first of the Pompeii to obtain the consulship was Quintus Pompeius in 141 BC, but by far the most illustrious of the gens was Gnaeus Pompeius, surnamed "Magnus", a distinguished general under the dictator Sulla, who became a member of the First Triumvirate, together with Caesar and Crassus. After the death of Crassus, the rivalry between Caesar and Pompeius led to the Civil War, one of the defining events of the final years of the Roman Republic.
Quintus Labienus Quintus Labienus Parthicus (died 39 BC), the son of Titus Labienus, was a Roman republican general, later in the service of Parthia. After the then main political power in Rome, Julius Caesar, was murdered by a conspiracy in 44 BC, Labienus took the side of the pro-republic conspirators, led by Brutus and Cassius, the latter of whom he served in the capacity of an ambassador to the Parthians. After Brutus and Cassius fled east to Macedonia and were defeated there in the Battle of Philippi by Caesar's imperialist successors (the Second Triumvirate, particularly Mark Antony and Caesar's heir Octavian, the future emperor Augustus), Labienus joined the Parthians.
