This article explores two related e?orts to transmit and inscribe the knowledge and practices of the Chagossian community in the context of forced displacement to Mauritius and Seychelles, and geographical dispersal between Mauritius, Seychelles, and the UK. The ?rst is the Mauritian government’s nomination of Chagossian sega (an IndianOcean genre of music and dance) to the UNESCO List of Intangible Cultural Heritage in Need of Urgent Safeguarding. The second is an AHRC project entailing a series of heritage transmission workshops with the Chagossian communities in Mauritius and the UK and an open access website hosting instructive cultural heritage materials generated at the workshops. Safeguarding sega o?ers the possibility of political, social, and ?nancial bene?ts such as increased legitimacy, strengthened collective identi?cation, and funding for cultural activities. It also risks loss of control over community knowledge and products. We show that e?orts to transmit and inscribe do not necessarily ‘freezecultural change’ into a ‘static element’, not least because there are limits to the extent to which people use a list, an inventory, or a recording as a guide to ‘living’ cultural practice.
