Gwenllian ferch Gruffydd

Who was Gwenllian ferch Gruffydd?

Gwenllian ferch Gruffydd was Princess consort of Deheubarth in Wales, and married to Gruffydd ap Rhys, Prince of Deheubarth. Gwenllian was the daughter of Gruffydd ap Cynan, Prince of Gwynedd and Angharad ferch Owain, and a member of the princely Aberffraw family of Gwynedd. Gwenllian's "patriotic revolt" and subsequent death in battle at Kidwelly Castle contributed to the Great Revolt of 1136.

There are several notable artistic depictions of Gwenllian. She is often confused with Gwenllian ferch Llywelyn, who lived two centuries later.
