陳守度
Toward the declining Lý monarch's power in late 12th century, the Trần clan from Nam Định eventually rise to power. In 1224, powerful court minister Trần Thủ Độ forced the emperor Lý Huệ Tông to become a Buddhist monk and Lý Chiêu Hoàng, Huệ Tông's 8-year-old young daughter, to become ruler of the country. Trần Thủ Độ then arranged the marriage of Chiêu Hoàng to his nephew Trần Cảnh and eventually had the throne transferred to Trần Cảnh, thus begun the Trần dynasty.
