Catuvellauni

The Catuvellauni were a tribe which existed in Britain before and during the occupation of the country by the Roman Empire in 43.

When Boudica, the Queen of the Iceni, encountered the Fourth Doctor and Leela in Norfolk in 60, she inquired if they belonged to the Catuvellauni. Leela told Boudicca that she was of the Sevateem, whom the Doctor claimed were located "as far north as you can go and then some." (BFA: The Wrath of the Iceni)
