The presence and influence of women in international relations and diplomacy is a subject that has received little attention in contemporary historiography. In this context and given the absence of systematic archive sources, oral history not only represents a novel and original source; it is also the most appropriate way of elucidating the role of female figures in European and international relations in Luxembourg after the Second World War. The aim of this oral history research project is to conduct semi-structured filmed interviews with women from a wide range of backgrounds (political, diplomatic, economic, trade union, cultural, technocratic, civil society, etc.) whose action left a mark on European and international relations in Luxembourg, then to publish them – in full, as a series of themed excerpts and in transcription form – on the C²DH research infrastructure. The resulting multimedia resources will also be shared with the Historical Archives of the European Union in Florence.
