Hywel "had a look of keen intelligence. This man was no fool."
- Hywel Dda (Hywel the Good) was born Hywel ap Cadell (Hywel son of Cadell).
- He inherited the whole kingdom of Seisyllwg (parts of modern Carmarthenshire and Ceredigion) in 911. Prior to this, Hywel became the legal heir to the southern kingdom of Dyfed, due to his marraige to Elen, the only child of King Llywarch ap Hyfaidd of Dyfed. From this would Hywel Dda work to form the new Kingdom of Deheubarth, which would form the south-western quarter of modern Wales.
