Magna Carta, imposed on King John by his barons in 1215, is widely regarded as the foundation of the British constitution. This is the classic study of the origins of the rebellion which culminated in the events at Runnymede. Professor Holt investigates the causes of the baronial revolt, and explores the social and administrative setting of the northern shires and their landed families. Professor Holt's introduction to the paperback edition draws on recent research on border societies to offer new insights into the organization of the northern barons. He also provides a valuable Guide to further reading.

This book is concerned with how the Northerners, many of whom were political outcasts and financial failures, came to influence the development of England. It analyzes the structure of their group and the motives behind their rebellion.
