Quick Summary

Branwen is a figure in Welsh mythology, appearing in the Mabinogi, a collection of medieval Welsh narratives rooted in Celtic myth and folklore. She is the daughter of Llyr, a sea deity, and sister to Brân the Blessed.12

Branwen's story, detailed in the "Branwen ferch Llŷr" branch of the Mabinogi, recounts her marriage to Matholwch, the king of Ireland. This union leads to conflict due to the treachery of Branwen's half-brother, Efnisien, resulting in a devastating war between Ireland and Britain. Branwen survives this war, along with a few others, and returns to Wales. She is also associated with the sun god Matholwch.12
