李聖宗
In the first month of 1072, Lý Thánh Tông died and was succeeded by the crown prince Lý Càn Đức, now called Lý Nhân Tông. After his coronation, Lý Nhân Tông gave the former empress Thượng Dương the title Empress Mother (Hoàng thái hậu) while his natural mother Ỷ Lan was granted the lower title Imperial Concubine Mother (Hoàng thái phi). Because the new emperor was only six years old, Empress Mother Thượng Dương held the regency for Lý Nhân Tông while the chancellor Lý Đạo Thành took charge in the royal court.
