Gwilym ap Tudur

Gwilym ap Tudur
Born	c. late 14th century
Died	1413

Gwilym ap Tudur (died 1413) was a Welsh nobleman and a member of the Tudor family of Penmynydd. In 1401, he and his brother Rhys ap Tudur took Conway Castle after infiltrating it, in support of their cousin Owain Glyndŵr. Gwilym was subsequently pardoned in 1413, following the execution of his brother a year earlier.

Gwilym was one of five sons of Tudur ap Goronwy and Marged ferch Tomos; alongside Ednyfed ap Tudor, Maredudd ap Tudur, Goronwy ap Tudor and Rhys ap Tudur. The family were descended from Ednyfed Fychan, and his son Goronwy ab Ednyfed, the founder of the Tudor family of Penmynydd.

Along with his brother Rhys, Gwilym was one of the leaders of a Carmarthenshire contingent of soldiers which had been raised in 1386 as a precaution against a French invasion via Ireland. They were each made an esquire to King Richard II of England, and accompanied his forces to Ireland in 1394. In 1398 their military service was retained by Richard, being paid a £10 stipend each year. They also once again accompanied Richard's forces to Ireland that year.

In September 1399, King Richard II was overthrown by Henry IV. When Gwilym's cousin Owain Glyndŵr began a rebellion the following year, in 1400, he and his brothers backed him openly. While Owain's rebellion in North East Wales faltered, Rhys and his family rose up against the king on Anglesey in September of that year. Henry IV personally took an army to put down the revolt, and harried the island, burning the Franciscan Llanfaes Friary near Bangor, Gwynedd, where the Tudur family were buried.
