Geta was Roman emperor alongside his father Septimius Severus and his older brother Caracalla from 209, and until 211 when he was murdered by Caracalla.
Following Geta's assassination, Caracalla ordered his brother's name to be removed from all inscriptions. The now sole emperor also took the opportunity to get rid of his political enemies, on grounds of conspiracy. Cassius Dio stated that around 20,000 men and women were killed or proscribed during this time.
Very few marble portraits attributable to Geta survive to date, presumably due to the very thorough damnatio memoriae which resulted in the erasing of his images. However Roman coins with his image are plentiful, and can reflect how his father Septimius Severus and later Geta himself wanted him to be seen by the Roman people (and especially the Roman military).
