Caracalla was not his official name
First of all, one of the most interesting facts about Caracalla is Caracalla was not his original name. Caracalla was born on April 4, 188, as Lucius Septimius Bassianus in Lugdunum. During the latter years of the reign of emperor Commodus, Septimius Severus served as the governor of Gallia Lugdunensis. At age 5, he received the title "Augustus," indicating that he belonged to a wealthy social elite. Caracalla's name was changed to Marcus Aurelius Antoninus when he reached the age of seven.
His father, who was now an emperor, oversaw it. His father desired a link between the current Nerva-Antonine Dynasty and the upcoming Severan Dynasty. As a result, the word Caracalla continued to describe a certain kind of cloak. While engaged in battle with Germanic tribes along the Roman Empire's boundary with the Danube River, he donned the tunic. The historians made derogatory use of this moniker. During the period, similar cloaks were worn by Roman emperors. As a result, the emperor's given name was never Caracalla.
The emperor was referred to as "Tarautas" by the ancient historian Cassius Dio. One of the most vicious and ferocious gladiators is mentioned. It offers a sense of how people at the time perceived Caracalla.
