陳守度
After the collapse of the Lý Dynasty, Trần Thủ Độ was still afraid that newly found ruling of the Trần Dynasty might be taken over by its political opponents, therefore he continued to eliminate member of Lý royal family by his ruthless method. On October 8 of Lunar calendar 1226, he forced the former emperor Lý Huệ Tông, who had already gotten rid of power to become a monk, to commit suicide and married Trần Thị Dung, Huệ Tông's former empress and his own cousin. These actions of Trần Thủ Độ was criticized by Ngô Sĩ Liên in his "Đại Việt sử kí toàn thư" as an inhumane decision despite his initial motive of reinforcing the reign of Trần Thái Tông.
