Trần Thủ Độ
After the collapse of the Lý Dynasty, Trần Thủ Độ was still afraid that the newly established Trần Dynasty might be overthrown by its political opponents. He therefore continued to eliminate members of the Lý royal family: first the former emperor Lý Huệ Tông in the tenth lunar month of 1226, then other members of the Lý royal family were massacred by the order of Trần Thủ Độ in the eighth lunar month of 1232.
