Hywel Dha (DDA) `the Good' ap CADELL  (887? - 948)  *
first, merged Dyfed and Seisyllwg into Deheubarth.
Like his grandfather, Rhodri, Hywel would come to rule most of Wales;

After Hywel's death Gwynedd regained its independence.
Hywel's three sons split the kingdom of Deheubarth,
but after Rhodri died in 953 and Edwin in 954,
Owain was able to reconsolidate it.    

Deheubarth

Owain ap Hywel (died 987) was king of Deheubarth in south Wales and probably also controlled Powys.
Rhodri ap Hywel (died 953) was a king of Deheubarth in south Wales, and son of Hywel Dda.
Edwin ap Hywel (d. 954) was a king of Deheubarth in south Wales, and son of Hywel Dda.

On Hywel's death in 950 Deheubarth was shared between Edwin, Rhodri and Owain. The sons of Hywel were not able to keep hold of Gwynedd, which was reclaimed for the traditional dynasty of Aberffraw by Iago ap Idwal and Ieuaf ap Idwal, the sons of Idwal Foel.  In 952 Iago and Ieuaf invaded the south, penetrating as far as Dyfed. The sons of Hywel retaliated by invading the north in 954, reaching as far north as the Conwy valley before being defeated in a battle at Llanrwst and being obliged to retreat to Ceredigion.

 Gwynedd

Iago ap Idwal (ruled 950 - 979) was a King of Gwynedd and possibly Powys, also referred to as "King of the Britons" by the Annals of Ulster.  Son of Idwal Foel, and on his father's death in battle in 942 would have expected to succeed to the rule of Gwynedd together with his brother Ieuaf ab Idwal. However Hywel Dda King of Deheubarth took the opportunity to invade Gwynedd and dispossess the young princes.

On Hywel's death in 950 Iago and Ieuaf were able to claim the throne of Gwynedd, driving out the sons of Hywel.

Ieuaf ap Idwal (ruled 950 - 969) was a king of part of Gwynedd and possibly part of Powys (in what today is called Wales).

The sons of Idwal Foel quarrelled and Iago took Ieuaf prisoner in 969, ruling Gwynedd alone until 979 when Ieuaf's son Hywel ap Ieuaf seized the throne from his uncle. According to J.E. Lloyd, Ieuaf remained in captivity until 988, which would imply that he was kept captive by his son.

Hywel ap Ieuaf (died 985) was a King of Gwynedd in north-west Wales from 979 to 985.

Cadwallon ap Ieuaf (died 986) was a King of Gwynedd.  Cadwallon was the son of Ieuaf ab Idwal and succeeded to the throne of Gwynedd on the death of his brother Hywel ab Ieuaf in 985. He only reigned for a year, for in 986 Maredudd ab Owain of Deheubarth invaded Gwynedd, slew Cadwallon and annexed his kingdom.


 

 

Maredudd ab Owain   986-99 999 also annexed Gwynedd from 986    

After Maredudd's death the combined kingdoms of Gwynedd and Deheubarth were ruled from Gwynedd by Cynan ap Hywel from 999-1005.

 Gwynedd (and sometimes Deheubarth)


 Cynan ap Hywel (ruled 999 - 1005) was a Prince of Gwynedd, one of the kingdoms or principalities of medieval Wales. After the death in 999 of Maredudd ab Owain who had seized Gwynedd from the line of Idwal Foel, the rule of Gwynedd returned to the original dynasty in the form of Idwal's great-grandson, Cynan ap Hywel.

Aeddan ap Blegywryd (died 1018) was a Prince of Gwynedd in medieval Wales.

After the death of Cynan ap Hywel in 1005, the throne of Gwynedd fell to Aeddan ap Blegywryd, who was apparently out of the direct line of succession. It is not known whether or not Aeddan seized the throne by force, but his lack of connection to the ruling family of Gwynedd suggests that he did. He reigned until 1018, when he was defeated in battle by Llywelyn ap Seisyll and killed together with his four sons.

Llywelyn ap Seisyllt, ruler of Gwynedd.

Iago ab Idwal ap Meurig (died 1039) was a Prince of Gwynedd.

Gruffydd ap Llywelyn (c. 1007 – August 5, 1063), was the ruler of all Wales from 1055 until his death, one of very few able to make this boast. He was great-great-grandson to Hywel Dda and King Anarawd ap Rhodri of Gwynedd.

Bleddyn ap Cynfyn (died 1075) was a Prince of the Welsh Kingdoms of Gwynedd and of Powys.

Trahaearn ap Caradog (died 1081) was a King of Gwynedd.

Gruffydd ap Cynan (standard Welsh: Gruffydd ap Cynan) (c. 1055 – 1137) was a King of Gwynedd.

 Two princes carried Wales through these difficult years, Owain Gwynedd in the north and Rhys ap Gruffydd in south Wales. Both were aware of the complex problems to be faced: to deal with rival Welsh dynasties, to deal with marcher lords, and to live in the shadow of a rich and powerful neighbor. Owain gauged the political realities of the day quickly and, however often he had to yield, he did not lose the initiative.

Rhys (II) ap GRUFFYDD  (1132? - 1197),  Lord Rhys, ruled Deheubarth and Wales, but paid homage to the King of England, Henry II
