supports: The Early Middle Ages (or early medieval period) marked the start of the Middle Ages of European History, lasting from the 6th to the 10th century C.E. 
  The Early Middle Ages followed the decline of the Western Roman Empire and preceded the High Middle Ages (c. 10th to 13th centuries). 
  The Early Middle Ages largely overlap with Late Ant1iquity. The term "Late Antiquity" is used to emphasize elements of continuity with the Roman Empire, while "Early Middle Ages" is used to emphasize developments characteristic of the later medieval period.  Glywys is a legendary early 5th century Welsh king , an important character in early Welsh genealogies as the eponymous founder king of Glywysing , a south - east Welsh kingdom whose heartland lay between the Tawe and the Usk . In one genealogy Glywys is reckoned the eldest son of Solor , son of Mor . He is said to have married Gwawl , the daughter of Ceredig of Ceredigion : one legend states they had twenty two children , all male bar one . fathered and the churchmen Pedrog and Edelig . According to twelfth century sources , after the death of Glywys the kingdom was divided into three cantrefi , Gwynllwg , Penychen and Gorfynydd , by his sons Gwynllyw father of Cadoc , Pawl and Merchwyn respectively , though Glwysing still existed and would later become Glamorgan . Gwynllyw gave his name to Newport Cathedral and also to Wentlooge , while Pawl may have been mixed up with Paul Aurelian . Glywys ' name may be a back - formation from the name of the kingdom and Glywysing 's name may continue that of the Romano - British * Glevenses , the territory and citizens of Glevum , or Gloucester . Such invented founding kings are not uncommon in British genealogy . `` Gloucester '' ( Glowancestre , 1282 ) derives from the Old English ceaster , `` fort '' , preceded by the Roman stem Glev - ( pronounced glaiw ) . In Old Welsh , the city was known as Caerloyw , caer = castle , and loyw from gloyw = glowing / bright . Hence Gloucester has been given a similar founder , Gloyw : genealogies of Vortigern make him a descendant of Gloyw through his father Vitalus and his grandfather Vitalinus , while a lineage in the Bonedd y Saint makes saint Mechyll fab Echwys the grandson of Gwyn Glohoyw and the great - grandson of Gloyw Wallt - Lydan . In the Mabinogi , similarly , Pryderi marries Cigfa , `` daughter of Gwyn Glohoyw , son of Gloyw Wallt - Lydan , son of Casnar Wledig '' . Nevertheless Glywys is believed to have become a hermit in his later life and travelled to Cornwall where he founded the church of Penryn . He is sometimes referred to as the Cornish Glywys , Glywys Cernyw . The Silures were a powerful and warlike tribe or tribal confederation of ancient Britain, occupying what is now south east Wales and perhaps some adjoining areas. They were bordered to the north by the Ordovices; to the east by the Dobunni; and to the west by the Demetae. Glywysing was, from the sub-Roman period to the Early Middle Ages, a petty kingdom in south-east Wales. Its people were descended from the Iron Age tribe of the Silures. A petty kingdom is a kingdom described as minor or "petty" by contrast to an empire or unified kingdom that either preceded or succeeded it (e.g. the numerous kingdoms of Anglo-Saxon England unified into the Kingdom of England in the 10th century, or the numerous Gaelic kingdoms of Ireland unified under the Kingdom of England as the Kingdom of Ireland in the 16th). Alternatively, a petty kingdom would be a minor kingdom in the immediate vicinity of larger kingdoms, such as the medieval Kingdom of Mann and the Isles relative to the kingdoms of Scotland or England or the Viking kingdoms of Scandinavia.
