Daniel Power studied at Selwyn College, Cambridge, from 1987, and held a research fellowship at Trinity Hall, Cambridge, from 1993. In 1996 he was appointed to a lectureship in the Department of History at the University of Sheffield, where he was promoted to Senior Lecturer in 2005 and Reader in 2007. He took up the post of Professor of Medieval History at Swansea University in September 2007. He is currently the Head of the Department of History and Classics.

Professor Power’s research concerns the history of France and the British Isles in the Central Middle Ages (especially the Anglo-Norman realm, the Angevin Empire, and Capetian France) and medieval frontier societies. His publications include The Norman Frontier in the Twelfth and Early Thirteenth Centuries (Cambridge: Cambridge University Press, 2004), and he has edited The Central Middle Ages (Short Oxford History of Europe (Oxford: Oxford University Press, 2006) and (with Naomi Standen) Frontiers in Question: Eurasian Borderlands 700-1700 (Basingstoke: Macmillan Press, 1999). His recent publications include a study of participants in the Albigensian Crusade, but they mainly concern the Anglo-Norman aristocracy in the 13th century, after the end of the Anglo-Norman realm in 1204, for which he established the database The ‘Lands of the Normans’ in England (1204-44); he is also preparing a critical edition of the 400 charters of the Hommet family, constables of Normandy in the 12th and 13th centuries.

Professor Power is the Director of MEMO, Swansea University’s Centre for Medieval and Early Modern Research. He is a Member of the Société de l'Histoire de France, and a Fellow of the Society of Antiquaries (of London) and the Royal Historical Society.

    The module is a basic introduction to the history of Europe c600-c1450, a period usually described as 'Medieval'. It outlines the political and economic structures of the period, and examines the medieval 'world view' by discussing attitudes to life, death and the afterlife. Its first theme, expansion, charts the growth of Europe as a major world power and includes topics such as the crusades against the Muslims and pagans, political and economic growth, and intellectual development in the foundation of the universities. Its second theme, crisis, focuses on the devastating impact of plague, famine and warfare, and the increasing persecution of heretics, lepers, homosexuals, and Jews.

  • HIH2069 The Crusades and the Making of Latin Christendom, 1050-1300

    The purpose of this module will be to examine the crusades by setting them in the context of the rapid expansion of Latin Christendom in the Middle Ages. The module will consider the crusades from the perspective of the Latin Christian society that created and sustained them, focussing on the major campaigns carried out to the Holy Land as well as the crusading expeditions to theatres including Byzantium, the Mediterranean, and within Western Europe. In so doing, it considers the impact of crusading activity at the 'periphery' or Europe - places including the Holy Land, Spain and Scandinavia - as well as at its 'core' - areas including France, Germany and the British Isles. The course will examine how the crusades influenced the military and cultural expansion of Latin Christendom in this era, as well as the impact of the crusading movement on ideas, institutions and developments within the heartlands of Europe.
