Geoffrey of Monmouth was a Catholic cleric from Monmouth, Wales, and one of the major figures in the development of British historiography and the popularity of tales of King Arthur. He is best known for his chronicle The History of the Kings of Britain which was widely popular in its day, being translated into other languages from its original Latin. It was given historical credence well into the 16th century, but is now considered historically unreliable.
The Battle of Badon, also known as the Battle of Mons Badonicus, was purportedly fought between Britons and Anglo-Saxons in Post-Roman Britain during the late 5th or early 6th century. It was credited as a major victory for the Britons, stopping the westward encroachment of the Anglo-Saxon kingdoms for a period.
Maelgwn Gwynedd was King of Gwynedd during the early 6th century. Surviving records suggest he held a pre-eminent position among the Brythonic kings in Wales and their allies in the "Old North" along the Scottish coast. Maelgwn was a generous supporter of Christianity, funding the foundation of churches throughout Wales and even far beyond the bounds of his own kingdom. Nonetheless, his principal legacy today is the scathing account of his behavior recorded in De Excidio et Conquestu Britanniae by Gildas, who considered Maelgwn a usurper and reprobate. The son of Cadwallon Lawhir ap Einion and great-grandson of Cunedda, Maelgwn was buried on Ynys Seiriol, off the eastern tip of Anglesey, having died of the "yellow plague"; quite probably the arrival of Plague of Justinian in Britain.
Uther Pendragon (Brittonic), also known as King Uther, was a legendary King of the Britons and father of King Arthur.
The Annales Cambriae is the title given to a complex of Latin chronicles compiled or derived from diverse sources at St David's in Dyfed, Wales. The earliest is a 12th-century presumed copy of a mid-10th-century original; later editions were compiled in the 13th century. Despite the name, the Annales Cambriae record not only events in Wales, but also events in Ireland, Cornwall, England, Scotland and sometimes further afield, though the focus of the events recorded especially in the later two-thirds of the text is Wales.
Cunedda ap Edern, also called Cunedda Wledig, was an important early Welsh leader, and the progenitor of the Royal dynasty of Gwynedd, one of the very oldest of Western Europe.
Cadwaladr, Cadwalader or Cadwallader is a given name and surname of Welsh origin meaning "battle-leader". It was most notably held by Cadwaladr, a seventh-century king of Gwynedd, who was the last Welsh king to claim lordship over all of Britain.
Cadwallon ap Cadfan was the King of Gwynedd from around 625 until his death in battle. The son and successor of Cadfan ap Iago, he is best remembered as the King of the Britons who invaded and conquered Northumbria, defeating and killing its king, Edwin, prior to his own death in battle against Oswald of Bernicia. His conquest of Northumbria, which he held for a year or two after Edwin died, made him one of the last recorded Celtic Britons to hold substantial territory in eastern Britain until the rise of the Welsh House of Tudor. He was thereafter remembered as a national hero by the Britons and as a tyrant by the Anglo-Saxons of Northumbria.
Myrddin Wyllt is a figure in medieval Welsh legend. In Middle Welsh poetry he is accounted a chief bard, the speaker of several poems in The Black Book of Carmarthen and The Red Book of Hergest. He is called Wyllt—"the Wild"—by Elis Gruffydd, and elsewhere Myrddin Emrys ("Ambrosius"), Merlinus Caledonensis or Merlin Sylvestris("of the woods"). Myrddin Wylt was born in 540 CE.
Cadafael was King of Gwynedd. He came to the throne when his predecessor, King Cadwallon ap Cadfan, was killed in battle, and his primary notability is in having gained the disrespectful sobriquet Cadafael Cadomedd.
Historia regum Britanniae, originally called De gestis Britonum, is a pseudohistorical account of British history, written around 1136 by Geoffrey of Monmouth. It chronicles the lives of the kings of the Britons over the course of two thousand years, beginning with the Trojans founding the British nation and continuing until the Anglo-Saxons assumed control of much of Britain around the 7th century. It is one of the central pieces of the Matter of Britain.
Peredur is the name of a number of men from the boundaries of history and legend in sub-Roman Britain. The Peredur who is most familiar to a modern audience is the character who made his entrance as a knight in the Arthurian world of Middle Welsh prose literature.
Cadfan ap Iago was King of Gwynedd. Little is known of the history of Gwynedd from this period, and information about Cadfan and his reign is minimal.
Iago ap Beli was King of Gwynedd. Little is known of him or his kingdom from this early era, with only a few anecdotal mentions of him in historical documents.
Idwal Iwrch, or Idwal ap Cadwaladr, reigned c. 682 – c. 720, is a figure in the genealogies of the kings of Gwynedd. He was the son of King Cadwaladr and the father of King Rhodri Molwynog. William Wynne places Cynan Dindaethwy as his son, but other sources have Cynan as the son of Rhodri. The records of this era are scanty, and Idwal's name appears only in the pedigrees of later kings and in a prophecy found in two 14th century Welsh manuscripts, which says that he will succeed his father Cadwaladr as king.
Rhodri Molwynog, also known as Rhodri ap Idwal was an 8th century king of Gwynedd. He was listed as a King of the Britons by the Annals of Wales.
Conan Meriadoc is a legendary British Celtic leader credited with founding Brittany. Versions of his story circulated in both Brittany and Great Britain from at least the early 12th century, and supplanted earlier legends of Brittany's foundation. His story is known in two major versions, which appear in the Welsh text known as The Dream of Macsen Wledig, and in Geoffrey of Monmouth's Historia Regum Britanniae. Both texts associate him with Magnus Maximus, a Roman usurper against the Valentinianic dynasty who was widely regarded as having deprived Britain of its defences when he took its legions to claim the imperial throne. Conan's cousin or sister, Saint Elen, is said to have been Macsen Wledic's wife.
The Battle of Chester was a major victory for the Anglo-Saxons over the native Britons near the city of Chester, England in the early 7th century. Æthelfrith of Northumbria annihilated a combined force from the Welsh kingdoms of Powys and Rhôs, and possibly from Mercia as well. It resulted in the deaths of Welsh leaders Selyf Sarffgadau of Powys and Cadwal Crysban of Rhôs. Circumstantial evidence suggests that King Iago of Gwynedd may have also been killed. Other sources state the battle may have been in 613 or even as early as 607 or 605 AD.
Lludd and Llefelys is a Middle Welsh prose tale written down in the 12th or 13th century; it was included in the Mabinogion by Lady Charlotte Guest in the 19th century. It tells of the Welsh hero Lludd Llaw Eraint, best known as King Lud son of Heli in Geoffrey of Monmouth's Historia Regum Britanniae, and his brother Llefelys.
Alain II Hir, "Alain II the tall",, also known as Alan Hir was a king of Brittany who succeeded his father Iudicael as King of Cornouaille; not to be confused with the contemporary Judicael, the King of Domnonee who was son of Iudhael, King of Domnonee.
