The Tudors of Penmynydd grew in power and influence during the 13th to 15th centuries, first owning land in north Wales, but losing it after Maredudd ap Tudur backed the uprising of Owain Glyndŵr in 1400. Maredudd's son, Owain ap Maredudd ap Tudur, anglicised his name to become Owen Tudor, and was the grandfather of Henry Tudor. Henry took the throne of England in 1485, at the end of the Wars of the Roses, when his forces defeated those of Richard III at the Battle of Bosworth Field.
