HCD is an international research network that aims to provide scholars interested in the history of cultural diplomacy with a forum to build research collaborations. It emerged as an endeavour by a group of scholars attending a workshop at Liverpool John Moores University in February 2025. Members are at different stages of their academic careers. They hold meetings periodically to discuss cultural interactions between countries from Europe, Asia, Latin America... We also publicise research works on the cultural dimension of international relations in the 19th and 20th centuries. A major purpose of the network is to open new paths for exploring international history.
