Who was the first king to marry a Western woman and ascend the throne twice in Vietnamese history?

Le Dynasty

The Later Le Dynasty had a total of 26 kings. Of which, the Early Le Dynasty had 10 kings (some documents recorded 11 kings) and the Later Le Dynasty had 16 kings. This was the feudal dynasty that had the most kings in Vietnamese history. According to the Brief History of Vietnam, the 10 kings of the Early Le Dynasty belonged to 6 generations including: Le Thai To, Le Thai Tong, Le Nhan Tong, Le Thanh Tong, Le Hien Tong, Le Tuc Tong, Le Uy Muc, Le Tuong Duc, Le Chieu Tong and Le Cung Hoang. This was the period when the Le Dynasty kings held all the power, and was also the great, golden age of the Vietnamese feudal regime. Some documents recorded that the Early Le Dynasty had 11 kings. The remaining king mentioned was Le Nghi Dan, who ascended the throne after overthrowing Le Nhan Tong. But less than a year later, he was overthrown by his mandarins because they thought he was incompetent and guilty of treason. Later, he was demoted to Le Duc Marquis and history books often do not consider him as the legitimate monarch of the Later Le Dynasty. The 16 kings of the restored Le Dynasty include: Le Trang Tong, Le Trung Tong, Le Anh Tong, Le The Tong, Le Kinh Tong, Le Than Tong, Le Chan Tong, Le Huyen Tong, Le Gia Tong, Le Hy Tong, Le Du Tong, Le De Duy Phuong, Le Thuan Tong, Le Y Tong, Le Hien Tong and Le Man De (Le Chieu Thong).
