李昭皇
For his merits during the war of resistance, in 1258 the Emperor Trần Thái Tông decided to grant Lê Phụ Trần a marriage with the former empress Lý Chiêu Hoàng who was downgraded to princess Chiêu Thánh after the 1237 event in which Lý Chiêu Hoàng was forced by grand chancellor Trần Thủ Độ to give up the position of Empress Consort of the Trần Dynasty for her elder sister Thuận Thiên, for the reason that she could not give birth to a child for Trần Thái Tông. Like the 1237 event, the marriage between Lê Phụ Trần and Princess Chiêu Thánh was criticized in historical books for the lack of moral code in marriage during the Early Trần period. Princess Chiêu Thánh deceased in Cổ Pháp in March 1278 at the age of 61. With the second husband Lê Phụ Trần, she had two children, Marquis Lê Tông and Princess Ứng Thụy Lê Khuê.
