Caracalla was a brutal fratricide
Not all of Septimius Severus' children were named Caracalla. Geta, his younger brother, was just eleven months younger than him. Over royal ownership, there was perpetual contention. Caracalla and Geta shared control of the Empire after the passing of their father. The two do not, however, have a connection like that of Marcus Aurelius and Lucius Verus. To become the single ruler, the two brothers continuously plotted against one another. Every time they attempted to decide on the future of the country as a whole, they clashed.
Herodian claims that the brothers partitioned the royal palace once things became worse. They even attempted to get their cooks to taint the meals of the opposition. Only Julia Domna, their mother, intervened to halt her son's wrongdoings. Otherwise, they succeeded in dividing the entire Empire.
Caracalla attempted to kill his brother once the partition of the Empire was disbanded. But his objective was a failure. A meeting with his mother and brother was then scheduled for the royal residences. Caracalla had his brother killed before Geta and his mother arrived. On December 26, 211, he accomplished it with the aid of centurions. His mother frequently sobbed.
Even though his sibling sought to hide in his mother's arms, Caracalla nonetheless managed to kill him. Caracalla didn't remain here. He gave the order to murder 20,000 of Geta's supporters.
