Publius Licinius Crassus Mucianus was the son of Publius Mucius Scaevola and Licinia, the sister of
Publius Licinius Crassus, consul in 171 BC. His paternal uncle,
Quintus Mucius Scaevola, had been consul in 174 BC. His elder brother,
Publius Mucius Scaevola, became consul in 133 BC. Thus, Crassus Mucianus was related to several consuls. His paternal grandfather,
Quintus Mucius Scaevola, had been
praetor in 215 BC, but had fallen ill and died before he could stand for election to the consulship. Crassus Mucianus was probably born around 180 BC. The date of his adoption is unknown. He married Clodia, (possibly the sister of
Appius Claudius Pulcher consul in 143 BC as well as censor and
Princeps Senatus in 136 BC). He had several children with her, of whom at least one son and two daughters outlived him. His younger daughter, Licinia, was wife of
Gaius Sempronius Gracchus, the would-be reformer who died in 121 BC. A cousin was
Quintus Mucius Scaevola Augur, consul in 117 BC, and friend, patron and tutor of
Cicero. Crassus Mucianus's nephew was the
rhetorician and jurist
Quintus Mucius Scaevola Pontifex, son of Publius Mucius Scaevola. Both relatives died or were killed during the
Social War. The family Mucii gained several consulships between 175 BC and 95 BC, including no less than three consuls who became
Pontifex Maximus (including Crassus Mucianus who was adopted out). ==See also==
