Name[edit] Glywysing
Glywysing
is said to be named after Glywys, a real or legendary early monarch, whose name may continue that of the Romano-British *Glevenses, the territory and citizens of Glevum
Glevum
(modern Gloucester).[2] According to 12th-century sources, after the death of Glywys, the kingdom was divided into seven cantrefs named for his sons:[3] Cydweli, Gwyr, Margam, Penychen, Gwynllwg, Gorfynydd, and another. These were typically ruled together by the head of the family and sometimes treated as appenage subkingdoms. Location[edit] The borders changed over time, but it is generally thought that its lands originally lay between the Afon Llwyd
Afon Llwyd
and the River Towy. At times they expanded eastwards to encompass both Gwent and Ergyng, but some time before the early 8th century, Cydweli
Cydweli
and Gwyr
Gwyr
(Gower) were lost to Dyfed. Today the area of Glywysing
Glywysing
is known as Glamorgan. Morgannwg[edit] In the mid 10th century, the kingdom merged with Gwent and changed its name to Morgannwg
Morgannwg
or Gwlad Morgan in honour of King Morgan the Old (r. 942–74)[citation needed] or his ancestor King Morgan the Generous (fl. c. 730).[4] Glywysing
Glywysing
seems to have been a sub-kingdom or principality of the Kingdom of Morgannwg, along with Gwent. After the death of Morgan the Old, Gwent and Glywysing
Glywysing
were separated again from 974 to 1055, but Glywysing
Glywysing
alone was often referred to as Morgannwg. Both areas were conquered by Gruffydd ap Llywelyn
Gruffydd ap Llywelyn
in about 1055, but on his death in 1063, Morgannwg, the union between Gwent and Glywysing, was reconstituted. How this occurred is unclear; possibly the Kings of Glywysing
Kings of Glywysing
were also Kings of Morgannwg
Morgannwg
and the Kings of Gwent were semi-independent under-Kings. The last native ruler of these areas was Iestyn ap Gwrgan, King of Morgannwg
Morgannwg
(1081-1090), who was deposed by Robert Fitzhamon. The name Morgannwg
Morgannwg
is still used in Wales
Wales
for the former county of Glamorgan
Glamorgan
(itself a corruption of the term Gwlad Morgan) and its successor counties. See also[edit]
