Rhys ap Tudur

Rhys ap Tudur (died 1412) was a Welsh nobleman of the Penmynydd family who twice served as sheriff of Anglesey under Richard II and joined his 1398 Irish expedition. In 1400 he backed his cousin Owain Glyndŵr's revolt against Henry IV.

With his brother Gwilym he infiltrated and seized Conwy Castle in 1401. Outlawed in 1406, Rhys was captured and executed at Chester in 1412. The bard Gruffydd Gryg mourned his death.
