Cicero, however, suggested an additional factor: the ambitions of the talented Publius Crassus, who had commanded successful campaigns in Gaul under Caesar. Upon his return to Rome as a highly decorated officer, Publius took steps to establish his own political career. Roman sources view the Battle of Carrhae not only as a calamity for Rome and a disgrace for Marcus Crassus but also as a tragedy that cut short Publius Crassus's promising career.
