The history of transcultural psychiatry has recently attracted much historical attention, including a workshop in March 2016 in which an international panel of scholars met at the Maison de Sciences de l'Homme Paris-Nord (MSH-PN). Papers from this workshop are presented here. By conceiving of transcultural psychiatry as a dynamic social field that frames its knowledge claims around epistemic objects that are specific to the field, and by focusing on the ways that concepts within this field are used to organize intellectual work, several themes are explored that draw this field into the historiography of psychiatry. Attention is paid to the organization of networks and publications, and to important actors within the field who brought about significant developments in the colonial and post-colonial conceptions of mental illness.
