The Cantiaci or Cantii were an Iron Age Celtic people living in Britain before the Roman conquest, and gave their name to a civitas of Roman Britain. They lived in the area now called Kent, in south-eastern England. Their capital was Durovernum Cantiacorum, now Canterbury.
Julius Caesar named five Celtic tribes inhabiting the land that would become the "heartland of the Catuvellauni": the Ancalites, the Bibroci, the Cassi, the Cenimagni, and the Segontiaci, each with their own 'king' or chieftain. He found their way of life to be very similar to their cousins in Gaul with whom they were close - the invasion of Britain may have been triggered by the Britons' supply of arms to the Gauls, who were being subjugated by the Romans.[page needed]
Caesar mentions four kings, Segovax, Carvilius, Cingetorix, and Taximagulus, who held power in Cantium at the time of his second expedition in 54 BCE. The British leader Cassivellaunus, besieged in his stronghold north of the Thames, sent a message to these four kings to attack the Roman naval camp as a distraction. The attack failed, a chieftain called Lugotorix was captured, and Cassivellaunus was forced to seek terms.
In the century between Caesar's expeditions and the conquest under Claudius (starting in 43 CE), kings in Britain began to issue coins stamped with their names. The following kings of the Cantiaci are known:
According to Nennius, Gwrangon was King of Kent in the time of Vortigern, until Vortigern took away the kingdom and gave it to Hengist; but Nennius is regarded as an untrustworthy source, and "Gwrangon seems to have been transported by the story-teller into Kent from Gwent" and "is turned into an imaginary King of Kent, secretly disposed of his realm in favour of Hengist, whose daughter Vortigern wished to marry".
