Cymbeline (Cunobelin) Chief of the Catuvellauni 
- Marriage: Unknown
- Died: 0042
Ruler of a large area of southeastern Britain from about AD 10 to 42. He is the Cymbeline in William Shakespeare's play of the same name, although the play's fanciful plot bears no relation to the events in Cunobelinus' career.
Cunobelinus succeeded his father, Tasciovanus, as chief of the Catuvellauni, a tribe centred north of what is now London. Either shortly before or shortly after his accession, Cunobelinus conquered the territory of the Trinovantes, in modern Essex. He made Camulodunum (Colchester) his capital and the seat of his mint. His power and influence were so extensively felt in Britain that the Roman biographer Suetonius referred to him as "Britannorum rex." About Ad 40 Cunobelinus banished his son Adminius, who thereupon fled to Rome and persuaded the emperor Caligula to make preparations to invade Britain. The expedition was assembled, but it never left the continent. After Cunobelinus' death, his two other sons, Caratacus and Togodumnus, displayed the hostility toward Rome that gave the emperor Claudius an excuse to impose Roman rule on the island.
Cymbeline reigned 26 B.C. to 17 A.D., according to one source. Wesbter's Biographical Dictionary (1st Ed.): "Cunobelinus or Cymbeline d. about 43 A.D. British king; ally of Augustus and chief ruler in Britain. Shakespeare's Cymbeline, named for him, is not historical."
