You do realise that only under Glyndwr did Wales unite , as nobody conquered Wales as such because It was Welsh region v Welsh region . All English kings would do is hire gwynedd to fight powys etc alongside his troops , as Welsh in fighting was fierce as still is today to certain degree.. if want to know about proper Welsh history , Owain Lawgoch was only man england really feared . Plus William Wallace , ( braveheart ) and St Patrick are both Welsh .
