 When Bảo Đại, the last Emperor of Vietnam, abdicated in August 1945 at Huế he is recorded to have surrendered the royal insignia to the new communist authorities.What happened to them after this is not known, but presumably they took them away, perhaps to Hanoi.In 1949 the former emperor became "Head of State" of the State of Vietnam, was not crowned, and was ousted by his Prime Minister Ngo Dinh Diem in a fraudulent 1955 referendum, and spent the rest of his life in exile.
