King Lud

Lud (Welsh: Lludd map Beli Mawr), according to Geoffrey of Monmouth's legendary History of the Kings of Britain and related medieval texts, was a king of Britain in pre-Roman times who founded London and was buried at Ludgate. He was the eldest son of Geoffrey's King Heli, and succeeded his father to the throne. He was succeeded, in turn, by his brother Caswallon (Latinised as 'Cassibelanus'). Lud may be connected with the Welsh mythological figure Lludd Llaw Eraint, earlier Nudd Llaw Eraint, cognate with the Irish Nuada Airgetlám, a king of the Tuatha Dé Danann, and the Brittonic god Nodens. However, he was a separate figure in Welsh tradition and is usually treated as such.^[1]

His name appears in the words Ludgate, Ned Ludd, and subsequently in 'luddite'.
