Gruffydd himself with Owain and Cadwaladr gained a crushing victory over the Normans at Crug Mawr near Cardigan the same year. In celebration of driving the English and the Fleming from South Wales, Gruffydd hosted a grand festival that lasted for 40 days. Death and succession In 1136 or early 1137 Gruffydd died in uncertain circumstances. Florence of Worcester claimed that Gruffydd was murdered by his second wife. He was succeeded by his son, Anarawd. Of his other sons, Cadell, Maredydd, and Rhys (later known as The Lord Rhys) all ruled Deheubarth in turn.
