  • Notes 


    • Llywarch ap Hyfaidd (died c. 904) was a king of Dyfed, an independent k i n g d o m in southwest Wales. Sometime after his death, Dyfed became part o f t h e n e w k ingdom of Deheubarth, ruled by Hywel Dda who was married to L l y w a r ch's daughter Elen.

      Upon Llywarch's death, the kingdom passed briefly to his brother Rhodri , b u t H y w el soon consolidated his rule, eventually merging Dyfed with h is p a t e r nal inheritance as the new kingdom of Deheubarth. Later Welsh t rad i t i o n held that Hywel inherited Dyfed peacefully through his suppose d m a r r i age to Llywarch's daughter Elen in a manner similar to the stori es t o l d a b out his great-grandfather Merfyn's acquisition of Gwynedd, hi s g r a n d father Rhodri's acquisition of Powys, and his father's acquisiti on o f C e r e digion, all of this despite female inheritance of land having n o p l a c e i n the Welsh law of the period. However, the repeated attacks o f C a d e l l and Hywel were recorded in Asser's Life of King Alfred, where i t s t a t e s Hyfaidd was replaced by his brother Rhodri, although the cause o f h i s d e a th is unknown.
