Trần Thủ Độ
His progress to the throne in particular and the replacement of the Trần Dynasty over the Lý Dynasty in general were mostly thanks to the efforts of Trần Thủ Độ, Trần Cảnh's uncle. At that time, Trần Thủ Độ was the front commander of capital of the Lý house. Trần Cảnh's father, Trần Thừa, was also an official under the Lý Dynasty, like Trần Thủ Độ. He had been "Nội thị khán thủ", one of the most important officials in the Lý Dynasty.
