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.
Augustus Augustus (Latin: "Imperātor Caesar Dīvī Fīlius Augustus" ; 23 September 63 BC – 19 August 14 AD) was the founder of the Roman Principate and considered the first Roman emperor, controlling the Roman Empire from 27 BC until his death in AD 14. He was born Gaius Octavius into an old and wealthy equestrian branch of the plebeian "gens" Octavia. His maternal great-uncle Julius Caesar was assassinated in 44 BC, and Octavius was named in Caesar's will as his adopted son and heir, then known as Octavianus (Anglicized as Octavian). He, Mark Antony, and Marcus Lepidus formed the Second Triumvirate to defeat the assassins of Caesar. Following their victory at the Battle of Philippi, the Triumvirate divided the Roman Republic among themselves and ruled as military dictators. The Triumvirate was eventually torn apart by the competing ambitions of its members. Lepidus was driven into exile and stripped of his position, and Antony committed suicide following his defeat at the Battle of Actium by Octavian in 31 BC.
