La Réunion is an island society shaped by racial and cultural contributions form Africa, Asia, India, Europe and Madagascar. Most of the ancestors of today's Réunionnais came to the island before and after the abolition of slavery in 1848. As the island itself has passed from being a colony to being a Département of metropolitan France, its inhabitants have passed from being slaves and then colonial subjects to being French citizens. Contemporary La Réunion is marked by radical Interculturalism and multiculturalism, the ethnocultural crossover known as métissage. This métissage is played out in a daily life through the paradigmatic phenomenon of créolisation. Créolisation and métissage refer not only to ethnicity, however, but also to crossovers in food, religion and belief, music, language, behaviour, norms, values, and so forth. The situation of La Réunion is unique. Moreover, as a former French colony and, since 1946, a Département, the island plays a key role in the Indian Ocean politics. Its geopolitical location and creolised character have enabled it to serve as an entrepot in the region; métissage have been marketed as cultural good. What i would like to ask in this paper is how cultural evetns and expressions contribute to the process of identity formation in La Réunion. What is of interest here is examining identity formation in relation to the processes of Diaspora of Indian Ocean people at large, particularly with reference to cultural factors (music, religion).
