Đồng Khánh
Tự Đức had no sons, but he had adopted three of his nephews. Dục Đức was 31 years old and the son of Kien Thoai Vuong, Tự Đức's fourth brother. Chánh Mông (who went on to rule as Đồng Khánh) and Duong Thien (who went on to rule as Kiến Phúc), aged 19 and 14 respectively, were sons of his twenty-sixth brother, Kiên Thái Vương.
