Descent

He was the only son of Llywelyn the Great by his wife, Joan (daughter of King John). In his last years Llywelyn went to great lengths to have Dafydd accepted as his sole heir. By Welsh law Dafydd's older half brother, Gruffydd had a claim to consideration as Llywelyn's successor. Llywelyn had Dafydd recognised as his named heir by his uncle King Henry III of England in 1220, and also had Dafydd's mother Joan declared legitimate by the Pope to strengthen Dafydd's position.

Conflict

There was considerable support for Gruffydd in Gwynedd, but although Dafydd lost one of his most important supporters when his mother died in 1237 he had the support of Ednyfed Fychan, the Sensechal of Gwynedd. Llywelyn suffered a paralytic stroke in 1237, and Dafydd took an increasing role in government. Dafydd ruled Gwynedd following his father's death in 1240. Gwynedd is an administrative county in Wales, named after the old Kingdom of Gwynedd. ... Ednyfed Fychan (died 1246), full name Ednyfed Fychan ap Cynwrig, was seneschal to the Kingdom of Gwynedd in northern Wales, serving Llywelyn the Great and his son Dafydd ap Llywelyn. ...

Although King Henry III of England had accepted his claim to rule Gwynedd, he was not disposed to allow him to retain his father's conquests outside Gwynedd. In 1241 the King invaded Gwynedd, and Dafydd was forced to submit. He had to give up all his lands outside Gwynedd, and also to hand over to the King his half brother Gruffydd whom he had been keeping a prisoner. Henry thereby gained what could have been a useful weapon against Dafydd, with the possibility of setting Gruffydd up as a rival to Dafydd in Gwynedd, but Gruffydd died trying to escape from the Tower of London by climbing down a knotted sheet, and fell to his death in early 1244.

Succession
