The March of Wales: A Borderland of Medieval Britain 1067-1300

the long version

"By 1300, a region often referred to as the March of Wales had been created between England and the Principality of Wales. This March consisted of some forty castle-centered lordships extending along the Anglo-Welsh border and also across southern Wales." "This book provides maps, a list of key dates and source material such as the writings of Gerald of Wales (c. 1146-1223), this book also places the March in the context of current academic debates on the frontiers, peoples and countries of the medieval British Isles."--Jacket.
