Gorboduc (Welsh:Gorwy or Goronwy) was a legendary king of the Britons as recounted by Geoffrey of Monmouth. He was married to Judon. When he became old, his sons, Ferrex and Porrex, feuded over who would take over the kingdom. Porrex tried to kill his brother in an ambush, but Ferrex escaped to France. With the French king Suhardus, he invaded Britain, but was defeated and killed by Porrex. Porrex was killed in revenge by his own mother Judon, then the high strata of society killed his mother and then there was a war between high strata and low strata leading to an anarchy in the society. This anarchy led to civil war denouncing Gorboduc.[1]Geoffrey does not state when Gorbuduc died, but he is not mentioned after the account of the strife between his sons.
