Lý Chiêu Hoàng
Lý Chiêu Hoàng was the ninth and last sovereign of the Lý dynasty from 1224 to 1225 and the only empress regnant in the history of Vietnam. Because she was only 6 when she succeeded to the throne, Lý Chiêu Hoàng ruled under the complete nfluence of Commander of Royal Guard Trần Thủ Độ and other members of the Trần clan. She was forced to marry another child when she was only 7, and her title diminished to Empress consort when her new husband, Trần Cảnh, was crowned. She was later further downgraded to “princess” when her husband stole another man’s pregnant wife and named her empress.
