Hồ Quý Ly
The Trần dynasty became known for emperors who reigned for only a few years before relinquishing the throne to a favorite son, and becoming Thái Thượng Hoàng Đế, the first dynasty to take the name of Father of "Hoàng Đế" emperor title. These types of short-lived and short-sighted emperors encouraged the arrival and ascension of strong, skillful and sly politicians. Hồ Quý Ly was such a politician. He was widely known for his cunning, courage, and boldness, and had distinguished himself in a successful campaign against the Chams of Champa. Through his scheming and shrewd marriage alliances (to a sister of Emperor Trần Duệ Tông and Trần Thuận Tông), Hồ Quý Ly made himself a court fixture in the position of the emperors' indispensable advisor. 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.
