Lý Huệ Tông
Besides the revolt of Đỗ Quảng, there were many warlords who rose up their troops against the rule of the Lý Dynasty. One of them, Đoàn Thượng, even self-entitled as Prince (Vương) and was so powerful that no generals of the Emperor could put down his revolt. These revolts with the incapability of the royal court made the ruling Lý Dynasty gradually weaken. In February 1213, afraid that his sister was ill-treated by the Empress Mother Đàm, Trần Tự Khánh led his army to the royal palace with the petition of receiving the Emperor, Trần Tự Khánh's action made Lý Huệ Tông suspected that he in fact wanted to overpower the Emperor, Huệ Tông thus ordered an issue of imprisoning Trần Tự Khánh and downgrading his sister Trần Thị Dung from Royal Consort ("nguyên phi") to palace maid ("ngự nữ"). The imprisonment of Trần Tự Khánh was not carried out and he again brought troops near Thăng Long in January 1214 with the same petition. Afraid that Trần Tự Khánh had a conspiracy against the royal family, Lý Huệ Tông decided to escape from Thăng Long to Lạng Sơn, always with the pursuit of Trần Tự Khánh. Only after Trần Tự Khánh put down the revolt of Đinh Khả and Bùi Đô in May 1214, the Emperor restored his sister as Lady Thuận Trinh (Thuận Trinh phu nhân). However, she was still distrusted by the Empress Mother Đàm who tried to force Trần Thị Dung commit suicide several times and finally Lý Huệ Tông had to escape with Lady Thuận Trinh to the garrison of Trần Tự Khánh in Cửu Liên Marsh (now Yên Mỹ, Hưng Yên). The first child of Huệ Tông and Lady Thuận Trinh, Princess Thuận Thiên was born here in June 1216.
