Publia Fulvia Plautilla, Fulvia Plautilla or Plautilla was a Roman Princess, briefly Roman Empress and the only wife to Roman Emperor Caracalla. Caracalla was her paternal second cousin.
Plautilla was born and raised in Rome. She belonged to the gens Fulvius of ancient Rome. The Fulvius family was of plebs origin, came from Tusculum, Italy and had been active in politics since the Roman Republic. Her mother was named Hortensia; her father was Gaius Fulvius Plautianus; the Commander of the Praetorian Guard, consul, maternal first cousin and close ally to Roman Emperor Lucius Septimius Severus (the father of Caracalla). She also had a brother, Gaius Fulvius Plautius Hortensianus.
Severus and Plautianus arranged for Plautilla and Caracalla to be married in a lavish ceremony in April 202. The forced marriage proved to be very unhappy; Caracalla despised her. According to Cassius Dio, Plautilla had a profligate character.
According to numismatic evidence, Plautilla bore Caracalla a daughter (whose name is unknown) in 204. In the same year, her father-in-law ordered the erection of the Arch of Septimius Severus, which honors Septimius Severus, Severus’ wife, Empress Julia Domna, Caracalla, Plautilla and her brother-in-law Publius Septimius Geta.
On January 22, 205 Gaius Fulvius Plautianus was executed for treachery and his family properties were confiscated. Plautilla and her daughter were exiled by Caracalla to Sicily and then to Lipari. They were treated very harshly, and were eventually strangled on Caracalla's orders after the death of Septimius Severus on February 4, 211.
