Llewelyn the Great
Llewelyn the Great (died 1240), Prince of North Wales and son of Iorwerth. His father was expelled from Wales, but Llewelyn recovered the country in 1194. In 1206 he married the illegitimate daughter of King John, but later supported the barons against the King, and was a beneficiary of Magna Carta. For many years he fought successfully against Henry III, but finally submitted in 1237. In 1239 he abdicated in favor of his son David and retired to a Cistercian monastery at Aberconway. Llewelyn gave generous encouragement to the bards, and his reign saw a renaissance of Welsh letters inspired by the King's defense of national unity.
