The Cantiaci or Cantii were an Iron Age Celtic people living in Britain before the Roman conquest and they lived in the area now called Kent. Their capital was Durovernum Cantiacorum, now Canterbury.
They were bordered by the Regnenses to the west, and the Catuvellaunito the north.
Julius Caesar landed in Cantium in 55 and 54 BCE, the first Roman expeditions to Britain. He regarded the Cantiaci as the most civilised and who similar to the Gauls in their customs.
Julius Caesar’sinvasion of Britain may have been triggered by the Britons' supply of arms to the Gauls, who were being subjugated by the Romans.
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 in 43 BCE, kings in Britain began to issue coins stamped with their names. The following kings of the Cantiaci are known:
Dubnovellaunus: May have been an ally or sub-king of Tasciovanus of the Catuvellauni, or a son of Addedomarus of the Trinovantes: Presented himself as a supplicant to Augustus c. 7 BCE.
Vosenius, ruled until c. 15 CE.
Eppillus, originally king of the Atrebates: Coins indicate he became king of the Cantiaci c. 15 CE, at the same time as his brother Verica became king of the Atrebates.
Cunobelinus, king of the Catuvellauni: Expanded his influence into Cantiaci territory.
Adminius, son of Cunobelinus: Seems to have ruled on his father's behalf, beginning c. 30 CE. He was exiled by Cunobelinus c. 40 CE, leading to Caligula's aborted invasion of Britain.
Anarevitos, known only from a coin discovered in 2010, probably a descendant of Eppillus and ruling c. 10 BCE - 20 CE.
