Caracalla is presented in ancient sources as a tyrant and cruel leader with psychopathic tendencies. He ruled jointly with his brother, until shortly after the death of his father Septimius Severus, when he ordered the murder of Geta. His greatest legacy was the Edict of Caracalla, granting Roman citizenship to nearly all freemen throughout the Roman Empire. He debased the coinage and introduced a new denomination called the antoninianus. The Baths of Caracalla were the second largest baths in Rome. He was murdered at the start of a campaign against Persia, by a disgruntled soldier passed over for promotion.
