李仁宗
Lý Nhân Tông's reign is highly applauded, above all in national education. Following the emperor's order, the first imperial examination of the Vietnamese monarch based on Confucian learning was organized in the second month in 1072 with Lê Văn Thịnh becoming the first first-rank laureate in the history of imperial examinations in Vietnam. Afterwards Lê Văn Thịnh was promoted to the position of chancellor in 1086. However the new Chancellor soon lost his position in 1096 after a controversial case of treason, was stripped of all titles, and banished. Besides Lê Văn Thịnh, Mạc Hiển Tích was also a capable official who found his way to the royal court from the Confucian learning that was continuously being developed by the emperor, especially after his decree establishing the first school for Confucian students in Đại Việt, "Quốc tử giám" (國子監, National Academy), in 1076. In 1089 Lý Nhân Tông made another important decision when he reformed the ranking of officials in the royal court and in the country. To protect the capital Thăng Long against floods, Lý Nhân Tông initiated the construction of the Cổ Xá Dike, one of the first dike systems in Đại Việt.
