Peter Abelard conducted many analyses of Scriptural and Patristic teachings, and achieved an extensive rapprochement between Christian and pagan thought. His public career was ended in 1140 by an ecclesiastical condemnation, but this touched upon the central issues facing the early leaders of the medieval scholastic movement and Abelard's own teachings continued to be controversial. Dr Luscombe considers the influence of Abelard's principal teachings among his contemporaries and successors. his aim is to explain the conflicting estimates of Abelard which were current in the twelfth century and later, and to provide a full account of the writings and varied fortunes of Abelard's disciples. He also examines the manuscript tradition of Abelard's work and that of his followers. The condemnation of 1140 repudiated Abelard's leading doctrines. This led some of Abelard's disciples to partly retreat from the position of their master, whereas some chose to adapt and extend his teachings.

The early historians of the Franciscan order traced the causes of the troubles of the order in their time to Elias, a contemporary and friend of St Francis and an early Minister General. Elias was blamed for opening the way to all relaxations of discipline and disregard of the founder's teaching, and all conflicts and persecutions. Mrs Brooke shows that responsibility cannot be placed on one man, but on many of the early friars. She gives a more historical account of Elias, showing that he was never as dominant a figure as has been supposed. The early conflicts of the order are shown to have been more complex, more interesting and more probable than the fourteenth-century controversialists would allow. The second part of the book describes the achievements of Elias's successors as Minister General, and the important laws they passed. Mrs Brooke has been able to reconstruct the early constitutions, now lost, in greater detail than has previously been attempted.

At the height of his power and influence the justiciar was the king's chief political and judicial officer, superintending the administrative machinery and acting as regent in the king's absence abroad. He was also a feudal lord or bishop; and the study of the careers of the chief justiciars, as soldiers and politicians, judges and financiers, throws light on the workings of feudal society and on the technical administrative means by which royal power was effectively exercised. Dr West traces the history of the office from the first need for the delegation of royal power under William 1 until the Anglo-Norman dominion broke up and government became too complicated. As an administrative post it attained its greatest importance in the formative periods of administrative development under Henry 1 and later under Henry 11. Unlike the offices of sheriff and chancellor the justiciarship has never been systematically examined. Dr West's book is a pioneer account of the most important office under the king and an examination of a central theme of English constitutional and administrative history.

This is a revised edition of R. C. Smail's classic account of the military achievements of the Crusaders in the context of a 'feudal society organized for war'. A new bibliographical introduction and an updated bibliography have been provided by Christopher Marshall, while the original plates section has been replaced by a series of new subjects. In covering the period 1097-1193, this edition also complements Dr Marshall's own Warfare in the Latin East, 1192–1291, also available in a paperback edition.
