Caracalla (in full: Marcus Aurelius Antoninus Caracalla) (188–217 A.D.), a Roman emperor. He is remembered for the Baths of Caracalla, large enough for 1,600 bathers, which he had built in Rome.
Caracalla was the eldest son of the emperor Septimius Severus. After their father's death in 211, Caracalla and his brother Geta became joint emperors. To secure the reign for himself, Caracalla had Geta and about 20,000 of his followers slain in 212. Caracalla, in turn, was killed by Macrinus, who became emperor.
