[2] His father and his younger brother, Publius, died at the Battle of Carrhae in 53 BC, after which time Marcus continued to be a partisan of Caesar.
[5] Both Ronald Syme and Elizabeth Rawson, however, have argued vigorously for a family dynamic that casts Marcus as the older but Publius as the more talented younger brother.
[10] In 49 BC, Caesar as dictator appointed Marcus governor of Cisalpine Gaul, the ethnically Celtic north of Italy.
The Augustan historian Pompeius Trogus, of the Celtic Vocontii, said that the Parthians feared especially harsh retribution in any war won against them by Caesar, because the surviving son of Crassus would be among the Roman forces, seeking revenge for the deaths of his father and brother.
Their son, the Marcus Licinius Crassus who was consul in 30 BC, seemed in his ambition and ability to have resembled his uncle Publius more than his father, in the reckoning made of the evidence by Ronald Syme.
