Three sons of Cunobelinus are known to history. Adminius, whose power-base appears from his coins to have been in Kent, was exiled by his father shortly before AD 40 according to Suetonius, prompting the emperor Caligula to mount his abortive invasion of Britain. Two other sons, Togodumnus and Caratacus, are named by Dio Cassius. No coins of Togodumnus are known, but Caratacus's rare coins suggest that he followed his uncle Epaticcus in completing the conquest of the lands of the Atrebates. It was the exile of the Atrebatic king, Verica, that prompted Claudius to launch a successful invasion, led by Aulus Plautius, in AD 43.
