Editing Gwenwynwyn (section)

==Lineage==
Gwenwynwyn ruled southern [[kingdom of Powys|Powys]] ([[Powys Wenwynwyn]]) from 1195, and was given charge of the kingdom following the retirement of his father [[Owain Cyfeiliog]]. Prior to this, in 1187, he had made an attack on [[Carreghofa Castle]] with his brother Cadwallon, in the course of which they killed their father's cousin and former ally, [[Owain Fychan]].<ref name=Acts/> He had assisted [[Maelgwn ap Rhys]] in taking [[Aberystwyth Castle]] and capturing Maelgwn's brother [[Gruffydd ap Rhys II]], whom he handed over to the English. His military ambitions were temporarily thwarted by his failure at the siege of [[Painscastle]], when Gruffydd returned to battle.<ref>{{cite book|author=Juliet Gardiner|title=The History Today Who's who in British History|url=https://books.google.com/books?id=dDMYAQAAIAAJ|year=2000|publisher=Collins & Brown|isbn=978-1-85585-771-1|page=377}}</ref>

Owain Cyfeiliog had been a notable poet as well as a leader of the resistance against English invasion, and chose to enter the abbey of [[Strata Marcella]] in later life; he died in 1197, two years after becoming a monk. Gwenwynwyn continued his father's strategy and is thought to have been one of the Welsh rulers who made an agreement with King [[Richard I of England]] not to attack his kingdom while he was away on crusade. In 1199, he made peace with Richard's successor, [[John, King of England|John]].<ref name=Acts>{{cite book|title=The Acts of Welsh Rulers: 1120–1283|url=https://books.google.com/books?id=4E2uBwAAQBAJ&pg=PA42|date=1 October 2010|publisher=University of Wales Press|isbn=978-0-7083-2387-8|pages=41–2}}</ref> He was rewarded with marriage to an English noblewoman, Margaret Corbet, the daughter of the Lord of the border territory of [[Caus Castle|Caus]], around 1200, as well as the grant of the manor of Ashford.<ref name=Acts/>
