Wikipedia Overview

The history of Gwynedd in the High Middle Ages is a period in the history of Wales spanning the 11th to the 13th centuries. Gwynedd, located in the north of Wales, eventually became the most dominant of Welsh polities during this period. Contact with continental courts allowed for Gwynedd to transition from a petty kingdom into an increasingly sophisticated principality of seasoned courtiers capable of high-level diplomacy and representation, not only with the Angevin kings of England, but with the king of France and the Papacy. Distinctive achievements in Gwynedd include the further development of medieval Welsh literature, particularly the work of the princely court poets known as Beirdd y Tywysogion and the reformation of bardic schools; and the continued development of Cyfraith Hywel. All three of these further contributed to the development of a Welsh national identity in the face of Anglo-Norman encroachment on Wales.
