The chronicles of medieval Wales are a rich body of source material offering an array of perspectives on historical developments in Wales and beyond. Preserving unique records of events from the fifth to the fifteenth centuries, these chronicles form the essential narrative backbone of all modern accounts of medieval Welsh history. Most celebrated of all are the chronicles belonging to the Annales Cambriae and Brut y Tywysogyon families, which document the tumultuous struggles between the Welsh princes and their Norman and English neighbours for control over Wales. Building on foundational studies of these chronicles by J. E. Lloyd, Thomas Jones, Kathleen Hughes, and others, this book seeks to enhance understanding of the texts by refining and complicating the ways in which they should be read as deliberate literary and historical productions. The studies in this volume make significant advances in this direction through fresh analyses of well-known texts, as well as through full studies, editions, and translations of five chronicles that had hitherto escaped notice.
