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.
Battle of Philippi The Battle of Philippi was the final battle in the Wars of the Second Triumvirate between the forces of Mark Antony and Octavian (of the Second Triumvirate) and the leaders of Julius Caesar's assassination, Marcus Junius Brutus and Gaius Cassius Longinus in 42 BC, at Philippi in Macedonia. The Second Triumvirate declared this civil war ostensibly to avenge Julius Caesar's assassination in 44 BC, but the underlying cause was a long-brewing class conflict between the "ancien regime" represented in the Senate (Optimates), and the rising class (Populares).
