The author produces revealing pictures of the leading Welsh kings and princes of the day and explores both their contribution to Welsh history and their impact on the wider world. They were, of necessity, warriors, living in a violent political world and requiring ruthless skills to even begin to rule in Wales. Yet they showed wider vision, political acumen tna statesmanship, and were patrons of the arts and the church. The history of their contact with their neighbours, allies and rivals is examined - Anglo-Saxons, Irish, Vikings, and Anglo-Normans - thereby setting Welsh institutions within their wider historical context.
