Đại Việt sử ký
Lê Văn Hưu began to compile the official historical text of the Trần Dynasty named "Đại Việt sử ký" (大越史記, "Annals of Đại Việt") during the reign of Trần Thái Tông. In this 30-volume ("quyển") text, Lê Văn Hưu comprehensively recounted the history of Vietnam from Triệu Đà, the first king of the Triệu Dynasty, to Lý Chiêu Hoàng which was the empress regnant and the last ruler of the Lý Dynasty. After the "Đại Việt sử ký" was finished, Lê Văn Hưu offered the book to the Emperor Trần Thánh Tông in January 1272 and was praised by Thánh Tông for its quality. Lê Tắc in his "An Nam chí lược" suggested that the "Đại Việt sử ký" was compiled by Lê Văn Hưu in revising the book "Việt chí" (越志, "Records of Việt") which was written by Trần Phổ under the order of Trần Thái Tông.
