There is a growing interest in the history of relations among the English, Scottish, Welsh and Irish as the United Kingdom and Ireland begin to construct new political arrangements and to become more fully integrated into Europe. This book brings together the latest work on how these relations developed between 900 and 1300, a period crucial for the formation of national identities. Little has been published hitherto on this subject, and the book marks a major contribution to a topic of lasting interest.
