Lý Thần Tông (1116–1138), personal name Lý Dðáng Hoán, was the fifth emperor of the Lý dynasty, reigning over ÃÂại Viá»Ât from 1127 to his death in 1138. Becoming the ruler of ÃÂại Viá»Ât at the age of twelve, Lý Thần Tông successfully maintained the order of the royal court and strengthened the stability of the country with the assistance of capable officials. For that reason, ÃÂại Viá»Ât under Lý Thần Tông was able to witness a peaceful period like during the reign of his predecessors. However, Lý Thần Tông died at age 22 before passing the throne to his crown prince Lý Thiên Tá»Â.
He was born in the summer of 1116 as Lý Dðáng Hoán to Lady ÃÂá» and the Marquis of Sùng Hiá»Ân (Vietnamese: Sùng Hiá»Ân hầu) who was son of the Emperor Lý Thánh Tông and younger brother of the Emperor Lý Nhân Tông. According to the ÃÂại Viá»Ât sá» ký toàn thð, Lý Dðáng Hoán was born right after the death of the monk Từ ÃÂạo Hạnh, one of the most important figures of the Early Lý dynasty, which implied that Lý Dðáng Hoán might be the incarnation of Từ ÃÂạo Hạnh. At that time, the Emperor Lý Nhân Tông was unable to have his own child, and thus he decided to adopt sons of the Marquises Sùng Hiá»Ân, Thành Khánh, Thành Quảng, Thành Chiêu, Thành Hðng, so that the emperor could choose a capable successor to maintain the throne for the Lý dynasty. Finally, being an intelligent and vivacious boy, Lý Dðáng Hoán was made by Lý Thần Tông the crown prince of the Lý dynasty at the age of two in 1117.
In December 1127, Lý Nhân Tông died at Vénh Quang Palace and was succeeded by the Crown Prince Lý Dðáng Hoán, now Lý Thần Tông. Immediately after the coronation, Thần Tông began to regulate the royal court and the royal family in order to keep the stability of the Lý dynasty in the wake of Nhân Tông's death. This action of Lý Thần Tông was criticized by contemporary historians Lê VÃÂn Hðu and Ngô Sé Liên who thought that Lý Thần Tông should have been in mourning for his predecessor for a longer period to show his respect for the departed emperor.
After the enthronement, Lý Thần Tông changed the era name to Thiên ThuáºÂn (1128–1132) and made his adoptive mother Lady Trần Anh the Empress Mother of the Lý dynasty. During the reign, the Emperor changed the era name one more time to Thiên Chðáng Bảo Tá»± (1133–1138).
Although he had been not long on the Lý throne, Lý Thần Tông at once made several major changes in the royal court such as relaxing strict laws, appointing officials for important positions and maintaining diplomatic relations with the Song dynasty and the Kingdom of Champa. At that time, the ÃÂại Viá»Ât's borders were fairly stable except for some skirmishes with the Khmer ruler Suryavarman II, starting in 1128, and Champa, which were driven out by the Lý army without difficulty. Besides the Emperor, the victory over Champa was also attributed to the protection of the Buddhist and Taoist deities, an opinion that the historian Lê VÃÂn Hðu did not agree with since the historian thought that the victory in battlefield was solely due to the ability of the commander.
In the first month of 1129, the Emperor bestowed his real father and mother Marquis Sùng Hiá»Ân and Lady ÃÂá» thá» on titles the Retired Emperor (Thái thðợng hoàng) and the Empress Mother (Hoàng thái háºÂu) of the Lý dynasty. The decision of Lý Thần Tông was met with criticism from Lê VÃÂn Hðu because of its unorthodoxy according to the feudal tradition in which the Emperor should accept only one origin, in this case was the late Lý Nhân Tông and his empress. Lê VÃÂn Hðu, together with Ngô Sé Liên, again criticized Lý Thần Tông for his order in the first month of 1130 that every daughter of the mandarins in the royal court had to be available for the emperor's selection of concubines and ones who were not chosen could only get married afterwards. Because of the young age of the emperor, Ngô Sé Liên and Lê VÃÂn Hðu often pointed their criticisms to Lý Thần Tông's officials who were considered ( by the historians ) lacking ability and being flatterers. However, Lý Thần Tông was later considered in the ÃÂại Viá»Ât sá» ký toàn thð a skilled ruler who was able to choose and use talented officials and hold the stability of the Lý dynasty. On the other hand, the modern historian Trần Trá»Âng Kim wrote in his Viá»Ât Nam sá» lðợc that ÃÂại Viá»Ât was able to witness a peaceful era during the reign of Lý Thần Tông thanks to some capable mandarins such as Trðáng Bá Ngá»Âc, Lðu Khánh ÃÂàm and Dðáng Anh Nhá» and the policy of "ngụ binh ð nông" which meant conscripting farmers into the army for a period of six months and release them for the remaining six months so that they could resume their farming work and thus the agriculture of the country was not affected by military activities.
In 1136 Lý Thần Tông contracted a severe disease that his physicians could not cure, so a monk named Nguyá» n Minh Không stepped up and helped the emperor survive his disease and recover. There was a legend said that Nguyá» n Minh Không learned the disease's antidote of disease from his master Từ ÃÂạo Hạnh before he died. Nevertheless, Lý Thần Tông survived for only two years, he died on the 26th day of the ninth month of 1138 at the age of 23 and was succeeded by Lý Anh Tông.
Lý Thần Tông entitled his empress, the Empress Consort Lá» Thiên (Lá» Thiên Hoàng háºÂu) Lý thá» in 1128. At the same time, Lý Thần Tông also married the niece Lê thá» of the chancellor Lê Xðáng, who was entitled as Lady Minh Bảo (Minh Bảo phu nhân).
The first son of Lý Thần Tông and Lady Minh Bảo Lê thá» was Lý Thiên Tá» who was born in the fourth month in Lunar calendar of 1136. Initially Lý Thiên Tá» was not chosen the crown prince of the Lý dynasty because his father preferred Lý Thiên Lá»Âc who was son of his favourite concubine and born before Lý Thiên Tá» in 1132. In the ninth month of 1138, the ill emperor decided to make Lý Thiên Tá» his successor and downgraded Lý Thiên Lá»Âc to Prince Minh ÃÂạo (Minh ÃÂạo vðáng) after a campaign opened by three other concubines of the Emperor, Ladies Cảm Thánh, NháºÂt Phụng and Phụng Thánh, who were afraid that the coronation of a concubine's son would menace their position in royal family. Besides Lý Thiên Tá» and Lý Thiên Lá»Âc, the emperor had a stillborn daughter in 1132, a third prince with unknown name born in 1137 and the Princess Thụy Thiên who was also born in 1137.
