Quick Summary

Manawydan fab Llŷr is a central figure in Welsh mythology, particularly within the tales of the Mabinogi. He is the son of Llyr, a sea god, and brother to Branwen and Bran the Blessed.12

Manawydan is associated with the sea, similar to his Irish mythological counterparts. He plays a significant role in the second branch of the Mabinogi, "Branwen Daughter of Llŷr," where he joins his brother Bran in avenging the mistreatment of their sister Branwen in Ireland. Following a devastating war that leaves few survivors, Manawydan marries Rhiannon, the mother of Pryderi, and becomes involved in further adventures that combat enchantments placed over Pryderi's realm.21
