However, it has been somewhat neglected by historians, who have tended to dismiss it as a satellite realm of England, and viewed its leaders as obstacles to the efforts of Gwynedd leaders to construct a principality of Wales. This book provides the first full, authoritative history of Powys in the twelfth and thirteenth centuries. It argues in particular that the Powysian rulers were dogged and resourceful survivors in the face of pressure from Welsh rivals and the problems of internal fragmentation; and that, paradoxically, co-operation with the English and intermarriage with marcher families underlay a desire to regain lands to the east lost in earlier centuries.
