The House of Gwynedd was a royal house during medieval Wales (c. 500 – 1500). The dynasty is seen as being divided between the founding of the kings settlement in Gwynedd during the Roman invasion of Britain and the subsequent kingdoms in Wales until the Norman invasion of Wales.
The royal house is defined by the timeline of the Kings of Gwynedd as direct male line descendants of the founder of the Kingdom of Gwynedd, Cunedda Wledig c. 401, until the subsequent era of the founding of the palace (Welsh: Llys) at Aberffraw c. 873, after the male line expired in the 8th century, because Gwynedd was inherited by Merfyn Frych, a female line descendant of Gwynedd from the Isle of Man. The dynasty lasted until the conquest of Wales by Edward I in the 13th century, and the deposition of the direct line of kings in 1283, and then the senior line of male heirs in medieval Wales, up until the 15th century.
