Llywelyn ap Gruffudd, also known as Llywelyn II and Llywelyn the Last, was Prince of Gwynedd, and later was recognised as the Prince of Wales from 1258 until his death at Cilmeri in 1282. Llywelyn was the son of Gruffudd ap Llywelyn ap Iorwerth and grandson of Llywelyn ab Iorwerth, and he was one of the last native and independent princes of Wales before its conquest by Edward I of England and English rule in Wales that followed, until Owain Glyndŵr held the title during his rebellion of 1400–1415.
