Llywelyn ap Gruffudd (died 11 December 1282), also known as Llywelyn II and Llywelyn the Last (Welsh: Llywelyn Ein Llyw Olaf), was Prince of Gwynedd from 1255 to 1282. After successful campaigns across Wales in 1257, Llywelyn proclaimed himself Prince of Wales in 1258, and was recognised as such by Henry III of England in 1267 as part of the Treaty of Montgomery. He remained in this position even after his humbling by Edward I of England in the 1277 Treaty of Aberconwy, remaining Prince of Wales in name until his killing at Cilmeri in 1282, one of the final events in Edward's conquest of Wales.
