Publius Licinius Crassus was one of two sons of Marcus Licinius Crassus, the so-called "triumvir", and Tertulla, daughter of Marcus Terentius Varro Lucullus. He belonged to the last generation of Roman nobiles who came of age and began a political career before the collapse of the Republic. His peers included Marcus Antonius, Marcus Junius Brutus, Decimus Junius Brutus Albinus, the poet Gaius Valerius Catullus, and the historian Gaius Sallustius Crispus.

Marcus Licinius Crassus was a Roman general and statesman who played a key role in the transformation of the Roman Republic into the Roman Empire. He is often called "the richest man in Rome".
