The practice of bequeathing the throne to a designated son (not simply passing it on to the eldest) was similar to what had happened in the previous Trần dynasty and was meant to avoid sibling rivalry.
In 2011, UNESCO declared the Citadel of the Hồ Dynasty in Thanh Hóa Province a world heritage site.
The Hồ/Hú family originated around modern-day Zhejiang province in the Southern Tang dynasty, which controlled much of southeast China, around the 940s.
In less than 20 years, while many others involved in court intrigues were being assassinated all around him, Hồ Quý Ly attained the highest post of General/Protector/Regent of the country in 1399.
After coaxing the emperor into relinquishing the throne to Prince An (a three-year-old child) he had Trần Thuận Tông imprisoned in a pagoda and later executed.
The descendants of the deposed Trần dynasty had begun agitating against the "usurper" Hồ Quý Ly.
This internal disquiet kept the country in chaos and allowed an opportunity for the Ming to conquer Đại Việt with the help of the Trần sympathizers.
[10][12] Thus, Trần Thiên Bính was escorted back by a military convoy, accompanied by a Ming ambassador.
[10] However, on 4 April 1406, as the party crossed the border into Lạng Sơn,[10] Hồ's forces ambushed them and killed both the prince[10] and the Ming ambassador.
At the Ham Tu battle, the Hồ family tried to escape the enemy but was caught by the Ming and sent to exile in China.
