Le Than Tong (1607-1662) was the 17th king of the Later Le Dynasty. When he was born, the Le Dynasty was only a nominal king, all power in Dang Ngoai belonged to the Trinh family, and Dang Trong was ruled by Lord Nguyen.

Le Than Tong ascended the throne for the first time in 1619, at the age of 12. He reigned until 1643, when he abdicated to his 13-year-old son, Le Duy Huu (Le Chan Tong), to become the Supreme Emperor. However, in 1649, King Le Chan Tong unfortunately passed away early, and King Le Than Tong returned to reign for the second time until his death (1649-1662).

Le Than Tong was famous for having many wives of different ethnicities. His first wife was Trinh Thi Ngoc Truc, daughter of Trinh Trang. The king was forced to marry Ngoc Truc when he was 23 years old and she was 36.

Later, to serve political and international trade purposes, the king is said to have married 5 more wives, of which the 2nd wife was Thai, the 3rd wife was Muong, the 4th wife was Han, and the 5th wife was Lao.

King Le Than Tong had a sixth wife who was Dutch. Her name was OurouSan, the daughter of the Dutch Vice-Governor in Taiwan. During a trip with the Dutch trade delegation to Vietnam in 1630, she met King Le Than Tong in the capital city of Thang Long. At that time, following her father's advice, she stayed in Vietnam to become King Le Than Tong's princess.

The six wives of King Le Than Tong lived together in harmony. Legend has it that the six statues of King Le Than Tong's six wives in Mat Son Pagoda, Thanh Hoa Province, were made by the six women who joined together to donate money, with the wish to be together forever.

Among them, the statue of Queen Trinh Thi Ngoc Truc sits on a lotus throne while the other ladies wear crowns in a meditative posture. Each statue shows a different facial expression and it is clear that each lady is wearing the same national costume as each person.

King Le Than Tong had 4 sons and 6 daughters. All 4 sons became kings. After his eldest son died, he ascended the throne for the second time and died 13 years later. He was succeeded by his second son, Le Duy Vu (also known as Huyen Tong). He reigned for 9 years before falling ill and passing away at the age of 18.

The successor was another son of Than Tong, named Le Duy Hoi (nickname Gia Tong), but he also did not overcome a serious illness after 4 years on the throne. Next, the youngest son of Le Than Tong, Le Duy Hop (nickname Hy Tong), succeeded to the throne. Le Hy Tong was the son who reigned the longest, 30 years, then abdicated to his son, Le Duy Duong (nickname Du Tong), and became the Supreme Emperor.
