A Welsh prince refers to a ruler or nobleman in Wales, particularly during the medieval period. The title is often associated with the Prince of Gwynedd, a prominent title held by leaders who sought to unify Wales and resist English domination. Notable figures include Llywelyn the Great and his grandson Llywelyn ap Gruffudd, who played significant roles in Welsh history. The title "Prince of Wales" is also used today, traditionally granted to the heir apparent of the British throne. This title was first used by Edward I in the 13th century after his conquest of Wales, symbolizing the ongoing relationship between Wales and England.
