Đại Thắng Minh Hoàng Hậu (Dương Vân Nga) is the only woman in Vietnam to become the queen of two different dynasties. From 968 – 979, she was the queen of the Dinh Dynasty; from 980, she was the queen of the Early Lê Dynasty.
In Vietnamese history, Dương Vân Nga is the only woman who has been queen twice, and she was the queen of two successive dynasties (the Dinh and Early Lê dynasties). King Đinh Tiên Hoàng made Dương Vân Nga his queen not only because of her political calculations, but also because of her beauty. But in her second time as queen, Dương Vân Nga, despite having children and no longer being young, was still chosen by Lê Đại Hành to be queen.

Which princess married two kings?
Princess Lê Ngọc Bình, born in 1783, is the youngest daughter of King Lê Hiển Tông (1717-1786) and Chiêu nghi Nguyễn Thị Điều. The people believe that Ngọc Bình is famous for her beauty and a unique fragrance that is highly attractive.
Princess Ngọc Bình married both King Cảnh Thịnh (of the Tây Sơn dynasty) and King Gia Long (of the Nguyễn dynasty). She is the only woman in Vietnamese history to marry two kings. There is a saying in Huế: “Some have strange destinies / The princess marries two kings as kings.”
Princess Lê Ngọc Hân and Lê Ngọc Bình have many similarities: they are both daughters of King Hiển Tông of the Later Lê dynasty; they were born in the North and both married emperors of the Tây Sơn dynasty; they were both queens in Phú Xuân.
Due to historical circumstances, Princess Ngọc Bình has the most unique destiny in the history of Vietnamese dynasties. Although Ngọc Bình did not leave many marks, she is part of a special history spanning three dynasties, the Lê, Tây Sơn, and Nguyễn dynasties.
At what age did Princess Lê Ngọc Bình get married?
In 1788, in Huế, Nguyễn Huệ became emperor, adopting the reign name Quang Trung and establishing the Tây Sơn dynasty. King Quang Trung appointed princess Ngọc Hân as his queen.
In 1792, Nguyễn Huệ suddenly died, and his son Quang Toản (the son of Quang Trung and queen Bùi Thị Nhạn from Bình Định) ascended to the throne at the age of 10, adopting the reign name Cảnh Thịnh.
In 1795, Queen Lê Ngọc Hân arranged a marriage between princess Ngọc Bình and Quang Toản, making her the primary queen of the Tây Sơn dynasty at the age of 12.
The marriage between princess Ngọc Bình and emperor Cảnh Thịnh created a complex relationship between Ngọc Hân – Nguyễn Huệ and Ngọc Bình – Cảnh Thịnh. Ngọc Hân and Ngọc Bình were both sisters and mothers-in-law. King Quang Trung and King Cảnh Thịnh were both fathers and sons as well as brothers, with their father-in-law being emperor Lê Hiển Tông.

Why did Princess Lê Ngọc Bình have to remarry?
In May 1801, Nguyễn Ánh captured Phú Xuân, and King Quang Toản fled to Bắc Hà, leaving Ngọc Bình and some palace maids behind in Phú Xuân. Seeing the young and beautiful queen, with her gentle speech and graceful demeanor, Nguyễn Ánh (King Gia Long of the Nguyễn dynasty) wanted to marry her.
Despite strong opposition from his courtiers, who believed that “there is no shortage of women in the world, so why marry the surplus wife of our enemy,” Gia Long ignored them all and replied, “We have taken everything from our enemies, so what is one woman?”
King Gia Long appointed Lê Ngọc Bình as his concubine, and she gave birth to two princes for the Nguyễn dynasty, Nguyễn Phúc Quân, Duke of Quảng Uy (born in 1809), and Nguyễn Phúc Cự, Duke of Thường Tín (born in 1810), as well as two princesses, Mỹ Khê Ngọc Khuê and An Nghĩa Ngọc Ngôn.
She died in 1810 at a relatively young age (27 years old) and was posthumously honored as Cung Thận Đức Concubine and buried in Trúc Lâm village. In 2008, her tomb was relocated to Mâm Xôi Hill in Đồng Chầm district, Hương Hồ ward, Hương Trà town.
