Einion Yrth, Venedos (Gwynedd), reigned 470s - 480s.  Little is recorded of Einion's period of authority. As one of the sons
                of Cunedda he must have been highly respected, and the fact that he inherited the core territory of North Wales, may
                suggest he was the senior of the sons who accompanied Cunedda to Wales.  With the help of his brothers, especially
                Ceredig, and his nephew Merion, Einion was able to build upon the conquests of his father and carve out the
                territories which became the later kingdoms of Gwynedd, Ceredigion and Meirionydd.
* Cadwallon Lawhir (Longhand), Gwynedd, reigned abt. 500-534.  A grandson of Cunedda and father of the notorious
                Maelgwyn, Cadwallon succeeded his father Einion as ruler of the Venedotian territory in north Wales.  We can
                derive some understanding of Cadwallon from his name and nickname.  Cadwallon became a common Welsh
                name, especially amongst rulers, because it translates as "battle leader", though this is its first appearance amongst
                the post-Roman rulers. Lawhir means longhand, and almost certainly refers to a physical attribute rather than
                meaning his power extended over a large area.  It was during Cadwallon's reign that Arthur gained his victory
                over the Saxons at Badon.  One noted episode remembered by the Welsh bards is that Cadwallon led his army
                into Anglesey to defeat the Irish and claim the island, which later became his base.  It is possible that Cadwallon was
                succeeded by a brother, whose name we do not know, who was subsequently murdered by Maelgwn.
* Maelgwn Hir, born abt. 497, Gwynedd, reigned abt. 520s-549, died in a plague.  Maelgwyn was one of the most
                powerful rulers of early sixth century Britain, so much so that he has been regarded by some as the original of king
                Arthur, especially as Gildas, who rebuked Maelgwyn severely in his Ruin of Britain, called him the "dragon of the
                island", a reference to the title of Pendragon or high king.  Neverless, with Maelgwyn, we have a king whose reign
                coincides with the height of Arthur's fame and who was certainly the senior king amongst the British after Arthur's
                death.  Maelgwyn's nickname, Hir means Tall, and his name, gwyn, means fair, so we can picture him as a tall,
                powerful, blond man, probably quite handsome.  Maelgwyn's life was turbulent.  Called by Gildas "first in evil",
                he was regarded as a vicous tyrant, but he also had a period of repentance during which he turned to the church,
                before he once again took up a life of tyranny.  Gildas records that in his youth he killed his uncle.  He is reputed to
                have founded the bishopric of Bangor and to have built or strengthened other churches.  He married, but soon his
                passions turned to his nephew's wife as his own.  His son and successor, Rhun, was almost certainly a child of the
                first marriage.  Maelgwyn was also the father of Brude, who was chosen by the Picts to be their leader.  By the
                time of his death Maelgwyn was firmly established as the primary ruler of the British, and a natural seccessor
                to Arthur.
* Rhun Hir, born abt. 520, Gwynedd, reigned abt. 549-580s. Sometime after his father's death, presumably around 500,
                Elidyr, the ruler of Rheged, who had married Rhun's sister, believed he had claim to Gwynedd, and more especially
                the island of Anglesey.  At this time Elidyr almost certainly ruled the Isle of Man as well and the islands of Man and
                Anglesey have a long historic association.  Elidyr's attempt at conquest, however, failed, for he was killed by Rhun.
                Rhun's half brother Brude, had recently been elected ruler of the Picts, which meant that Rhydderch and Clydno
                were trapped between a growing dynastic power to north and south. Mustering forces from all over north Wales,
                Rhun led an army, probably the greatest force that had been seen since the days of Arthur, and marched from
                Wales up through Rheged (Lancashire) and across the Pennines to York.  In all that march, which lasted several
                months, Rhun was unopposed.  In effect he exercised authority over all of north Wales and northern Britian and,
                in alliance with Brude, extending into the lands of the Picts.  Rhun could have sought to establish a major kingdom.
                But he did not have a sufficient power base back in Wales to sustain such rule, and though his authority was
                recognized, he did not take control of the territory.  Instead he made peace with Peredur of York, apparently
                marrying his cousin Perwyr, and then returned to Gwynedd.  One can conjecture that during that period he
                established Gwynedd as a prosperous and strong kingdom not threatened by any outside powers.
* Beli, Gwynedd, reigned 580s-599.  Little is known about the reign of Beli, even though he inherited a powerful and stable
                Kingdom.  He was succeeded by his son Iago.
* Iago, Gwynedd, reigned abt. 599-613. The name Iago is the Welsh equivalent of Jacob or James.  It was during his reign
                that the power of the Angles in Mercia grew under Pybba and his son Penda.  In 604, Athelfrith had driven Edwin
                out of Northumbria and the young king sought refuge at the courts of Iago and Selyf of Powys.  Athelfrith,
                determined to be rid of Edwin turned his wrath against the Welsh; it seems that the Mercians provided little
                assistance.  Althelfrith slaughtered the monks of a monastery at Bangor and then his forces defeated and killed
                Selyf at the Battle of Chester.  It is not recorded that Iago took part in this battle; in fact it is suggested that
                Iago may already have abdicated as king and died that same year in a monastery.  He was succeeded by Cadfan.
* Cadfan, Gwynedd, reigned abt. 615-620, died abt. 625.  Cadfan is remembered as a wise king, which suggests that not
                only did he adminster the laws justly to his subjects, but that he also succeeded in maintaining peace at a time of
                growing hostility between the Welsh and the Angles, especially the Northumbrian king Athelfrith. Despite Athelfrith's
                victory at the Battle of Chester, Cadfan continued to shelter Edwin, the Northumbrian prince whom Athelfrith was
                intent on killing.  When Athelfrith was himself killed in battle four years later, Edwin was restored to his throne.
                He did not show any particular favouritism to his saviours, however; he bacame intent on conquering other Celtic
                land, including Elmet, Rheged and Man, and was eventually killed by Cadfan's son Cadwallon.
* Cadwallon, born 590s, Gwynedd, reigned 620s-634, in exile 620-627, killed in battle.  Once restored to the throne, Edwin
                determined to conquer Britain.  He soon captured the British kingdom of Elmet and deposed its king Ceredig.
                With the death of Cadfan, Edwin invaded North Wales, driving the Welsh back toward the sea.  Cadwallon,
                unprepared, fled to the islet of Priestholm, off Anglesey, and from there escaped to Ireland.  His elile lasted about
                seven years, during which time Edwin's authority spread over all of northern England and Wales and the Isle of Man.
                Around 626 Edwin was converted to Christianity and ceased his conquests.  Cadwallon returned from Wales and
                was restored to his kingdom, though as a vassal to Northumbria.  Cadwallon entered into alliance with Penda,
                and Edwin was killed, as were most of his family and many of his nobles. Cadwallon had regained the old
                kingdom of his forebears, for it was from Northumbria that Cunedda had come two centuries before.  Cadwallon
                could have been a great king.  He was remembered as such by the Welsh because, for one brief period, he
                re-established the might of the British against the Saxons.  Had he been a wise king he could have restored
                British might and glory.  But he lost this chance, and the British never again regained such power.  At his death
                he was only in his late thirties.  His son, Cadwaladr was too young to take power, and Gwynedd was lost to
                an adventurer called Cadfael.
* Cadfael Cadomedd ap Cynfeddw, reigned 634-abt. 655, usurper, later deposed.  On the death of Cadwallon in
                battle, Cadfael seized the throne of Gwynedd.  Cadfael may have been raised in the court of Gwynedd and been      given some degree of authority when Cadwallon went to war with Edwin of Northumbria in 630 or 631.  Whatever his origins, he clearly had strong control of Gwynedd as he remained in power for over twenty years.  He fought alongside Penda in the
                fatal battle of Winwaed in 655 where Penda fell.  Cadfael fled the battlefield.  He may have died soon after,
                possibly killed by Cadwaladr, or he may have fled into exitle.
* Cadwaladr Fendigiad (the Blessed), Gwynedd,  reigned abt. 655-682, died in a plague. Cadwaladr was perhaps the
                last great British hero, remembered in Welsh texts almost like another Arthur.  He was presumably raised in
                exile either in Ireland, or in one of the neighbouring Welsh kingdoms.  The native Venedotians of Gwynedd did
                not like their usurper king Cadfeal; they hailed Cadwaladr as a promised saviour to deliver them from his yoke
                and to conquer the English again, echoing the achievements of Cadwallon.  Unfortunately he did not live up to
                their expectations.  In 658 he led an army against the West Saxons at Peonne in Somerset and was soundly
                defeated.  Thereafter he seems to have spent his years establishing peace and prosperity in Gwynedd, rather
                than attempting to conquer to English.  He is the last British king recorded by Geoffrey of Monmouth in his
                History of the Kings of Britian, and his death seems to mark the end of the last chapter of British resistance
                against the Saxons.
* Idwal Iwrch (Roebuck),  Gwynedd, reigned abt. 682-720.  After the death of Cadwaladr the history of the Welsh
                ruling houses enters a dark period for over a century until the emergence of Merfyn Frych and Rhodri (the
                Great).  Like his father, therefore, he was probably not warlike, but preferred to rule wisely and pay
                countenance to the church.
* Rhodri Molwynog, reigned abt. 720-754.  His reign concides with that of Athelbald of Mercia who, by 736 was
                styling himself King of Britain.  There were no other strong Welsh chieftains at this time and we can imagine
                Rhodri and his family clinging proudly to their heritage, which they could trace back to Cunedda and Coel.
                It is suggested that he was succeeded by a distant cousin, Caradog ap Meirion.
* Caradog ap Meirion, reigned abt. 754-798, killed in 798.  It is likely that during this period the royal house of Gwynedd
                withdrew to their stronghold on Anglesey.  Caradog was the ruler of Rhos and claimed descent from Einion's
                son Owain.  Caradog was almost certainly ruler in 768, the year in which Elfoddw, the bishop of Gwynedd,
                persuaded the Welsh church to adopt the church of Rome's method of calculating Easter, which had been the
                main rift between the Roman and Celtic churches since the Synod of Whitby under Oswy of Northumbria in 664.
                Caradog faced increasing encroachment from the Saxons who were invading Powys during this period.  Caradog
                seems to have met his death from the Mercians under Cenwulf, although other records state that he was strangled.
* Cynan ap Rhodri, reigned abt. 798-816.  It is not exactly clear who ruled Gwynedd in the last years of the eighth century.
                Although it is not clear when he came to power, certainly by the year 813 it is recorded that he was waging a
                civil war with Hywel, who was either his brother or a distant cousin.  Hywel gained the upper hand in 814, but
                Cynan won back control in 816, only to die later that year.  Cynan almost certainly sought help in his war from
                Gwriad, the ruler of the Isle of Man, who had married Cynan's daughter Essyllt.  Essyllt became the mother of
                Merfyn Frych who established a new dynasty in Gwynedd and began the re-establishment of Gwynedd's power.
* Hywel, Gwynedd, reigned 814-825.  Hywel has variously been identified as the son (or grandson) of Rhodri ap Idwal or
                the son of Caradog ap Meirion.  Whichever was the case, he appeared on the scene in a dynastic struggle with
                his brother or distant cousin Cynan ap Rhodri over the rulership of Gwynedd, and in particular over the
                heartland of Anglesey.  Hywel either left no children or all had died in the many skirmishes during these dark
                days for, after his death, power was taken by Cynan's grandson Merfyn Frych.
* Essyllt
   = Gwriad
* Merfyn Frych (the Freckled), Gwynedd, reigned abt. 825-844 son of Gwriad of Man. After the reign of Hywel 814-825.
                Merfyn came to power following the death of Hywel ap Caradog, and his accession marked the end of a period
                of turmoil in Gwynedd's affairs and the start of a new dynast.   Merfyn was the son of Gwriad, the king of the
                Isle of Man, through whom he could claim descent from Llywarch Hen.  His mother was Essyllt, the daughter
                of Cynan ap Rhodri, who was descended from the main line of Venedotian kings since the days of Cunedda.
                Merfyn married Nest, the daughter of Cadell ap Brochfael of Powys.  His alliance with Powys meant that the
                two kingdoms presented a powerful front to the Saxons in the east.  Merfyn thus established a stable, if uneasy
                peace.  Merfyn Frych died in 844 passing his reign to his son Rhodri Mawr who would become king of all
                North Wales.
* Rhodri, Rhodri, succeeded to the kingdoms of Powys in 855 and that of Seisyllwg in 872, becoming king of all
                North Wales. Under him and his successors Gwynedd entered its period of greatness.  After Cynan's death
                Powys passed to his nephew Rhodri Mawr and formed part of the kingdom of Gwynedd until the death of
                Bleddyn ap Cynfyn in 1075.
