The British constitution is unique in being both unwritten and the product of many centuries of evolution, at times peaceful and at times set against a background of violent conflict. Its nature, and its many unusual features, cannot be understood without a knowledge of the forces which shaped that evolution. This book provides an accessible one-volume introduction to the development of the British constitution from its earliest beginnings in the 7th century to the present day. It focuses on the political events, and social, religious and philosophical ideas which have shaped the constitutions development. It is designed for university undergraduates studying law, history, politics and related subjects.
