King of Gwynedd from 1240 to 1246.
Birth and descent
Though birth years of 1208, 1206, and 1215 have been put forward for Dafydd, it has recently been persuasively argued that he was born shortly after Easter 1212. Born at Castell Hen Blas, Coleshill,

Welsh law, Dafydd's older half-brother
Gruffydd had a claim to be Llywelyn's successor. Llywelyn had Dafydd recognised as his named heir by his uncle
King Henry III in 1220 and also had Dafydd's mother Joan declared legitimate by the

of Gwynedd who wielded great political influence. 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.
Although Henry III had accepted his claim to rule Gwynedd, he was not disposed to allow him to retain his father's conquests outside Gwynedd. As the diplomatic situation deteriorated, Dafydd began to explore alliances with others against Henry and is known to have sent ambassadors to the court of
Louis IX of France

. In August 1241, however, King Henry III invaded Gwynedd, and after a short campaign, Dafydd was forced to submit. Under the terms of the
Treaty of Gwerneigron, 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 imprisoned. 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 in March 1244 Gruffydd fell to his death while trying to escape from the

Dyserth also fell to his men in the summer. In August 1245 King Henry again invaded Gwynedd, but his army suffered a defeat in a narrow pass by Dafydd's men. Undaunted, Henry proceeded as far as the river Conwy and began building a new castle at

. After a flurry of diplomatic activity by Henry, the decision was reversed in 1245. Savage fighting continued at Deganwy until Henry, some of whose supplies had been captured by the Welsh, ran short of provisions. A truce was agreed and Henry's army withdrew in the autumn. The truce remained in effect throughout the winter, but the war was effectively ended by the sudden death of Dafydd in the royal home at
Abergwyngregyn, in February 1246. He was buried with his father at
