• Notes

  Dafydd (Welsh for "David") was the only legitimate son of Llewelyn the Great, and was due to inherit his father's land and title. However Dafydd's illegitimate elder brother, Gruffydd (Welsh for "Griffith") contested the inheritance. King Henry III of England took advantage of the dispute and led a campaign against Dafydd in 1245. Dafydd died a year later.
