Plautilla ? - 211
Plautilla was the wife of Caracalla. This unhappy union came about by insistence of Septimius Severus, Caracalla's father, who wanted to show his appreciation and support for Plautianus, his Praetorian Prefect. Caracalla apparently hated her for her imperious and snobby ways and warned her that the only reason she was with him in the first place was in deference to his father's wishes.
Alarmed at what Caracalla might do to her, Plautianus then set up a hasty plot to kill his friend Severus but the plot was revealed and he was executed. Shortly after Severus's death Caracalla made good on his threats and exiled her to an island. This not being good enough he had her executed sometime after.
