The "Prince of Gwynedd" refers to the title held by the rulers of the Kingdom of Gwynedd, a significant region in medieval Wales. This title was most notably associated with Llywelyn the Great and his grandson Llywelyn ap Gruffudd, who played crucial roles in the struggle for Welsh independence against English rule during the 13th century. Gwynedd was a powerful kingdom that emerged in the early Middle Ages, known for its rich culture and strong leadership. The princes of Gwynedd sought to unify the various Welsh kingdoms and resist external threats, particularly from the English crown. Their legacy is an essential part of Welsh history and identity.
