The rise and fall of Dương Nhật Lễ was the starting point for a series of chaotic events in the royal court that led to the collapse of the Trần Dynasty.
[6] Only half a year after taking the throne, the new emperor ordered the poisoning of the Great Queen Mother Hiến Từ, who had begun to regret her support for the coronation of Nhật Lễ.
In the tenth month of 1370, the Emperor's father-in-law, Trần Phủ, after receiving advice from several mandarins and members of the royal family, decided to raise an army for the purpose of overthrowing Nhật Lễ.
[12] Subsequently, Hôn Đức Công killed a mandarin named Ngô Lang who had advised him to surrender and abdicate the throne to Nghệ Tông.
[5] After the death of Hôn Đức Công, his mother fled to Champa and begged King Chế Bồng Nga to attack Đại Việt.
[13]: 92–93 Taking advantage of the neighbour's lack of political stability, Chế Bồng Nga commanded troops and directly assaulted Thăng Long, the capital of Đại Việt.
