The Kingdom of Gwynedd was a Welsh kingdom which first appeared at the turn of the sixth century. Based in northwest Wales, the rulers of Gwynedd repeatedly rose to dominance and were acclaimed as "King of the Britons" before losing their power in civil wars or invasions. The kingdom of Gruffudd ap Llywelyn—the King of Wales from 1055 to 1063—was shattered by a Saxon invasion in 1063 just prior to the Norman invasion of Wales, but the House of Aberffraw restored by Gruffudd ap Cynan slowly recovered and Llywelyn the Great of Gwynedd was able to proclaim the Principality of Wales at the Aberdyfi gathering of Welsh princes in 1216. In 1277, the Treaty of Aberconwy between Edward I of England and Llywelyn's grandson Llywelyn ap Gruffudd granted peace between the two but would also guarantee that Welsh self-rule would end upon Llywelyn's death, and so it represented the completion of the first stage of the conquest of Wales by Edward I.

Kingdom of Gwynedd in Depth

History, background and familial descent

The background involving the Kingdom of Gwynedd starts with the history of Wales. After the last ice age, Wales was settled during the prehistoric times. Neolithic sites have been discovered with tools made from flint, such as near Llanfaethlu, a long house excavated from 6000 years ago. Further examples of human activity in Gwynedd and Anglesey are involved in places such as Bryn Celli Ddu on Anglesey, which was built in phases starting 5000 years ago. Archeological findings from the Bronze Age, millennia ago, include findings such as the Arthog cauldron, a bronze cauldron from 1100 BC found near the Merioneth border, also named 'The Nannau Bucket' (similar to the Dowris bucket).

Military

According to Sir John Edward Lloyd, the challenges of campaigning in Wales were exposed during the 20-year Norman invasion. If a defender could bar any road, control any river-crossing or mountain pass, and control the coastline around Wales, then the risks of extended campaigning in Wales were too great.

The Welsh were revered for the skills of their bowmen. Additionally, the Welsh learned from their Norman rivals. During the generations of warfare and close contact with the Normans, Gruffudd ap Cynan and other Welsh leaders learned the arts of knighthood and adapted them for Wales. By Gruffudd's death in 1137, Gwynedd could field hundreds of heavy well-armed cavalry as well as their traditional bowmen and infantry.

Legacy

Following Edward's conquest, the lands of Gwynedd proper were divided among the English counties of Anglesey, Caernarfonshire, Merionethshire, Denbighshire, and Flintshire. The Local Government Act 1972 reformed these, creating a new county (now called a "preserved county") of Gwynedd which comprised Anglesey and Llyn, Arfon, Dunoding, and Meirionydd on the mainland. The modern principal area of Gwynedd established by the Local Government (Wales) Act 1994 no longer includes Anglesey.
