Lý Huệ Tông
In March 1210 Trần Tự Khánh with his army of Trần's house servants helped the Crown Prince return to the capital, Thăng Long; therefore he was awarded the title Count Thuận Lưu (Vietnamese: Thuận Lưu bá). One year after, the Crown Prince Lý Sảm was enthroned as Lý Huệ Tông after the death of Lý Cao Tông, by then the Trần clan's position began to rise in the royal court. After his coronation, Huệ Tông ordered Trần Tự Khánh to bring his sister to royal palace, the mission was successfully conducted by Trần Tự Khánh's subordinate Phùng Tá Chu who also helped general Tô Trung Từ pacify the revolt of Đỗ Quảng near Thăng Long. As a result, Tô Trung Từ was promoted to Regent of the Emperor while Trần Tự Khánh was also granted the title Marquis Chương Thành (Chương Thành hầu).
