李惠宗
In 1210, Lý Cao Tông died. Lý Hạo Sảm was enthroned as Emperor Lý Huệ Tông. General Tô Trung Từ gained too much power that he was killed by other officials. His nephew Trần Tự Khánh, amassed an army and threatened the capital. Emperor Huệ Tông then turned to warlord Đoàn Thượng who rebelled earlier for help, but they were defeated by Tự Khánh. The emperor had to escape to Lạng Sơn.
