About Rhys ap Rhydderch
Rhys ap Rhydderch was a Welsh ruler.
Rhys ap Rhydderch was the brother of Gruffydd ap Rhydderch, king of Deheubarth from 1044 to 1052. Both were the sons of Rhydderch ab Iestyn, who had been able to take over the Welsh kingdom of Deheubarth from 1023 to 1033.
After his death, Rhys' head was brought to King Edward on 5 January 1053. This left his brother as the only ruler in Deheubarth, but this did not last long, as around 1055, Gruffydd ap Llywelyn attacked the south and killed Gruffydd ap Rhydderch. This left Gruffydd ap Llywelyn as the sole ruler of Wales, the first Welshman to be so.
