This latest volume by Jean Richard is concerned with the evolution of the crusading movement and with the interaction between crusaders and indigenous peoples of the Near East. The articles look at changes in the concept of crusading, means of financing it, and forms of indulgence; at how the adoption of maritime transport created a need to control the sea, and how contacts with the Muslims could lead to peaceful means of resolving conflict and dealing with prisoners. In their lands in the east, the Latins accommodated the feudal structures they brought with them to local conditions, especially in the mountains. Both in this and in the religious sphere compromises were made, and in this co-existence each community preserved its individuality. The final section then considers roles played by eastern Christians in the contacts between Europeans and Mongols. Si les origines de la croisade retiennent l'attention, son volution m rite elle aussi int r at. La conception de la croisade, les modalit s du financement, la forme d'indulgence, se sont modifi es; l'adoption du transport par bateau a n cessit la prise du contr le de la mer. Les affrontements avec les Musulmans ont provoque des contacts, ainsi pour r gler le sort des prisonniers; on a chech des solutions pacifiques au conflit. Dans leurs possessions orientales, les Francs ont adapt le r gime seigneurial aux conditions locales et, tout en gardant intacte leur structure f odale, r serv , surtout dans les montagnes, leur place aux chefs indig nes, Les contacts de civilisation sont r els, mais chaque communaut garde some individualit . Il en est de m ame dans le domaine religieux, o il a fallu adopter des compromis pout permettre une r elle coexistence. Et finalement les chr tiens orientaux ont t les agents du rapprochement entre Francs and Mongols.
