Addressing several issues of significance in the fields of Anthropology of Migration, Politics of Healthcare, Religious and Francophone Studies, this book pursues an unprecedented line of research by bringing to the fore the geopolitical dimension of francophonie, understood as a political construct, as much as a cultural, artistic and a linguistic space, with French as common language. The book is based on participant observation carried out in Paris in a foyer among Soninke migrants, the principal ethnographic focus, and at the secondary field-site based at the Mouride Islamic Centre of Taverny, which serves to show an important facet of the so-called Francophone Islam.
