The numerous and voluminous reports and letters which the Jesuits wrote on the Moro mission, as on all their missions in Asia, are perhaps of less interest to us now for what they reveal of the methods adopted by the Society of Jesus in this remote corner of their mission field or the details they contain about the successes and failures of individual missionaries, than for the wealth of information they provide on the islands where the Jesuits lived and the indigenous societies with which they came into contact through their work of evangelization. In other words, it is not theprimary purpose of this essay to analyse the Jesuit documents with a view to reconstructing the history of the Moro mission in narrative form but rather to glean from them some of the informationthey contain about the social and political conditions in Moro during the forty years or so in the sixteenth century when both the Jesuit missionaries and the Portuguese were active in the regio Because the Jesuits were often in close touch with local rulers and notables, whether or not they succeeded in converting them to Christianity, and because they lived among their subjects for long
periods, depending upon them for the necessities of life and sharing their hardships, their letters and reports often show a deeper understanding of the social, economic and political conditions of the indigenous societies and, one suspects, give a more accurate and measured account of events and personalities than do the official chroniclers and historians of the time, most of whom never ventured further east than Malacca and who in any case were chiefly concerned to glorify the deeds of the Portuguese and justify their actions to the world.
