Gruffydd ap Llywelyn had managed to bring all of Wales under his control by 1055, however English attacks led by Harold Godwinson on his territory led to the collapse of his Wales into the traditional Kingdoms. What if he had done better in battle, and managed to hold Wales together? He would have lived longer, though probably not that much longer, though maybe to the Norman Conquest. Would the Kingdom be able to hold together at his death? How would this affect the Norman invasion of England?
