Over a weekend of memorials, I was remembering a friend who died of a broken heart. Her death certificate may not say so, but she did. Aurélie Lisette Talate died last year at 70 of what members of her community call, in their creole language, sagren—profound sorrow. Madame Talate died of sagren because the U.S. and British governments exiled her and the rest of her Chagossian people from their homeland in the Indian Ocean’s Chagos Archipelago to create a secretive military base on Chagos’ largest island, Diego Garcia.
