The first eight studies in this volume seek to address a series of questions concerning the emergence and the role of the military orders in the 12th and 13th centuries: the reasons for the appearance of the institution, the recruitment and instruction of novices, and, though the military orders were predominantly male organisations, the role of women within them. Dr Forey then turns to the orders' role in the Crusades, both against the infidel and in 'Holy Wars' against Christians, and their activities in ransoming captives. The last studies focus on the development of the Order of St John, and on two minor military orders; one of these, that on St Thomas of Acre, draws attention to the relations between England and the Holy Land, the subject also of the final paper, on the crusading plans of Henry III.
