This is the research blog of a webinar launched in 2021 on the history of “Foreign consulates and consuls in France in the twentieth century”. It is animated by three French associate professors in contemporary history : Marion Aballéa (Université de Strasbourg), Judith Bonnin (Université Bordeaux Montaigne) and Jérémy Guedj (Université Côte-d’Azur). You can find here informations on the webinar, a link to a participative bibliography created on Zotero, datas found in primary sources (diplomatic directories, consular collections, questionnaire, etc.), and first results and analyses (historical maps, statistical analyses).
