This short article rapidly skims through the history of Mongol studies in the West since Petis de la Croix, from the viewpoint of the gradual opening of primary sources, and with particular interest in the development of the French School of Mongolian studies, long dominated by the figures of Paul Pelliot (on him, supra review 36) and Louis Hambis. More originally, special paragraphs deal with the Japanese School and its specific efforts on the history of the Mongols in East Asia, since the invention of the field by Yanai Wataru, as well as to the Chinese and Mongol Schools of Mongol studies. Individual sections cast light on the work on individual scholars. Unfortunately, these evocations remain quite elusive, focusing on a state of the art that has been completely renewed in the past thirty years, and the ensemble does not really reach the level of an epistemological appraisal. The text is followed by a short bibliography of Mongol studies in very different languages, with very few contributions posterior to the 1970s.
