The name 'Caracalla' originates from the Latin term 'caracalla,' which referred to a type of hooded tunic worn by the Gauls. It was later adopted as the agnomen, or nickname, of the 3rd-century Roman emperor Marcus Aurelius Antoninus, who is more commonly known by this name. The name is historically significant due to its association with the emperor's reign, which included notable events such as the issuance of the Antonine Constitution and the construction of the Baths of Caracalla.
