"Regionalism and Cosmopolitanism: South India" is the research blog of its namesake, a thematic workshop in the Centre for South Asian Studies (Centre d'études de l'Inde et de l'Asie du Sud, CEIAS, UMR 8564, CNRS-EHESS, Paris). Its object is the study of the South Indian region over the long term with a multidisciplinary approach (history, anthropology, geography, philology). Its aim is to contribute to the description of the special features and shared traits of this regional culture, which, throughout its history, has been submitted to a bi-directional movement of cosmopolitanism and regionalism.
