Understanding our system of laws requires a knowledge of the past, in particular the roots of a legal tradition that took hold in medieval England. This landmark volume is an authoritative study of the inspirational and legal history of England, spanning the period of Richard III on Bosworth Field in 1485. In writing this book, Bryce Lyon has produced a work whose breadth of scholarship is unique among studies of the period. Each of its six sections includes chapters on local and central government and the law, as well as on such topics as feudalism, taxation, church-state relations, the Magna Carta, and parliament. With a modern's cognizance of the impact of bureaucracy in shaping government and law, Professor Lyon places special emphasis on the importance of administrative developments. He also demonstrates that many of medieval England's institutions and legal procedures are the forerunners of both modern English and American legal and governmental institutions, pointing out, for example, the close connection between medieval royal prerogative and modern presidential executive privilege, and the similarities between the procedures and privileges of the medieval parliament and the American Congress. The new edition incorporates the results of the last two decades of medieval scholarship and includes completely new bibliographies for each section, as well as a new discussion of the period 1399-1485, which takes into account the latest interpretations of Lancastrian and Yorkist history.

Fully revised and updated, this classic text provides the authoritative introduction to the history of the English common law. The book traces the development of the principal features of English legal institutions and doctrines from Anglo-Saxon times to the present and, combined with Baker and Milsom's Sources of Legal History, offers invaluable insights into the development of the common law of persons, obligations, and property. It is an essential reference point for all lawyers, historians and students seeking to understand the evolution of English law over a millennium. The book provides an introduction to the main characteristics, institutions, and doctrines of English law over the longer term - particularly the evolution of the common law before the extensive statutory changes and regulatory regimes of the last two centuries. It explores how legal change was brought about in the common law and how judges and lawyers managed to square evolution with respect for inherited wisdom.
