Rud Hud Hudibras (Welsh: Run baladr bras) was a legendary king of the Britons as recounted by Geoffrey of Monmouth. He came to power in 974BC.
He was the son of King Leil and ruled during a civil war.
Story
During the waning years of Leil's reign, the kingdom of the Britons became unstable, and civil war broke out. Rud Hud Hudibras became king after his father's death and reigned for 39 years, ending the civil war and restoring peace to the kingdom. During his reign, he founded Kaerreint, later renamed Canterbury by the Angles. He is also said to have founded Kaerguenit (Winchester) and Paladur Castle (Shaftesbury). He was succeeded by his son Bladud.
