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.

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.

[1] The nomen Pompeius (frequently anglicized as Pompey) is generally believed to be derived from the Oscan praenomen Pompo, equivalent to the Latin Quintus, and thus a patronymic surname.

[5][1] The other branch, which played a conspicuous role in the final decades of the Republic and under the early Empire, mainly used personal cognomina, such as Strabo, Magnus, Pius, and Faustulus.

[8][9] Magnus, or "great", was originally an epithet of the triumvir, who won renown as a general under Sulla's command, and later on his own; his sons and some of their descendants also used the name to signify their connection to him.
