\b0 He was born at Lyons in 188 to Septimius Severus and
Julia Domna. His name derives from a mantle used by the Gauls that the young emperor liked to wear. At the age of fourteen he married Plautilla, whom he later confined to the island of Lipari, and at the age of twenty-three became co-emperor with his br
other Geta, for whom he nursed a deep hatred. In fact in February 212 he had him killed by two centurions. He was a ruthless and cruel ruler. He liked to imitate Alexander the Great and the invincible Achilles of the Iliad. He promulgated the famous Cons
titutio Antoniana that gave Roman citizenship to all the subjects of the Empire. To restore faith in the currency he created the ½Antonine,╗ containing a larger proportion of silver, but this measure proved insufficient to check inflation. He began the c
onstruction of the Baths in Rome that are named after him. He died at Carrae in Mesopotamia at the age of twenty-nine, murdered on the orders of the Praetorian prefect Macrinus. In 218 he was deified by Elagabalus.\par
