Trần Thánh Tông (October 12, 1240 â July 3, 1290), personal name Trần Hoảng (), was the second emperor of the Trần dynasty, reigning over ÃÂại Viá»Ât from 1258 to 1278. After ceding the throne to his son Trần Nhân Tông, Thánh Tông held the title of retired emperor () from 1279 until his death in 1290. During the second and the third Mongol invasions of ÃÂại Viá»Ât, Retired Emperor Thánh Tông and Emperor Nhân Tông were credited as the supreme commanders who led the nation to the final victories and, as a result, established a long period of peace and prosperity over the country. With his successful rulings in both military and civil matters, Trần Thánh Tông was considered one of the greatest emperors of not only the Trần dynasty but also the whole dynastic era in the history of Vietnam.
Trần Hoảng was born on the 25th day of the ninth lunar month in 1240, as the second prince but the first natural son of emperor Trần Thái Tông and Empress Consort ThuáºÂn Thiên. He had a half-brother on the mother's side, Prince Ténh Quá»Âc () Trần Quá»Âc Khang, who was born after the forced marriage by Trần Thá»§ ÃÂá» between Emperor Thái Tông and Princess ThuáºÂn Thiên. In fact, although being Thái Tông's first prince, Trần Quá»Âc Khang was the son of his elder brother Prince Hoài Trần Liá» u, therefore officially he was not chosen by Thái Tông as the heir, a position which ultimately belonged to Prince Trần Hoảng. Besides Prince Ténh Quá»Âc, Trần Hoảng had other younger brothers, including Prince Chiêu Minh Trần Quang Khải (who was also born to Empress ThuáºÂn Thiên), Prince Chiêu Quá»Âc Trần ÃÂch Tắc, and Prince Chiêu VÃÂn Trần NháºÂt DuáºÂt.
In 1257, Crown Prince Trần Hoảng witnessed the first Mongol invasion in Vietnam. In the beginning, ÃÂại Viá»Ât's army suffered several defeats by the Mongols, who had already conquered a vast area in Asia. Several high-ranking officials of the Trần dynasty were so frightened that Prince Khâm Thiên Trần NháºÂt Hiá»Âu, younger brother of Thái Tông, even suggested to the Emperor that they might escape from ÃÂại Viá»Ât to Song China. But because of the firm faith of Emperor Thái Tông, Grand Chancellor Trần Thá»§ ÃÂá»Â, and the talents of generals such as Prince Hðng ÃÂạo Trần Quá»Âc Tuấn and Lê Phụ Trần, the Trần dynasty was able to repulse the invasion and ultimately re-establish peace in ÃÂại Viá»Ât in December 1257.
Returning to the capital ThÃÂng Long, Trần Thái Tông decided to cede the throne to Crown Prince Trần Hoảng, now Trần Thánh Tông, on the 24th day of the second lunar month (March 30), 1258. After the coronation, Thánh Tông changed the era name to Thiá»Âu Long (; 1258âÂÂ1272). During his reign, the Emperor had one more era name, Bảo Phù (; 1273âÂÂ1278). Although passing the throne to his son, Thái Tông continued to rule the country with Thánh Tông in the position of retired emperor from 1259 to his death in 1277.
After his enthronement, Thánh Tông and his father began to rehabilitate both the country's economy and administrative system, which had been heavily damaged by the Mongol invasion and the troubled time at the end of the Lý dynasty. In June 1261, the king opened an examination for scholars who wanted to be appointed as mandarins of the administrative system. The examination comprised two abilities of writing and calculating. In the royal court, Thánh Tông proved to be a skilled ruler with his often right appointment of officials, such as his brother Prince Chiêu Minh Trần Quang Khải for the position of grand chancellor, or Lê Phụ Trần and Prince Hðng ÃÂạo Trần Quá»Âc Tuấn for the position of military commander. For members of the royal family, Thánh Tông had them hire the poor to cultivate their land, thus creating social reform.
In March 1266, Trần Thánh Tông ordered his first imperial examination to be carried out, in which more than 50 scholars were chosen for high-ranking positions in the royal court and administrative system of ÃÂại Viá»Ât. For the purpose of educating more scholars for the royal court, Thánh Tông permitted his brother Trần ÃÂch Tắc to open a private school at the latter's palace due to his intellectual ability. Several prominent future mandarins of the royal court, including Mạc ÃÂénh Chi or Bùi Phóng, were trained in this school. At the same time, the Emperor also reinforced ÃÂại Viá»Ât's army by several recruitments, and by reorganizing the military to improve its efficiency. In addition, Trần Thánh Tông always kept a vigilant eye on the northern border by sending several scout units to learn about military actions of the Yuan dynasty, the potential threat against ÃÂại Viá»Ât.
After the death of Retired Emperor Trần Thái Tông on April 1, 1277 (in the lunar calendar), Trần Thánh Tông officially began his reign as the sole ruler of ÃÂại Viá»Ât, but he decided to pass the throne to Crown Prince Trần Khâm, now Trần Nhân Tông, only one year later. He took up the post of retired emperor on the 22nd day of the tenth lunar month (November 8), 1278.<Ref name=calendar> The second option on the left tab allows for the lunar date to be entered on the top green row, and gives a conversion to Gregorian date, and vice versa.</ref>
In 1268, the Yuan court sent Hulonghaiya to the Vietnamese capital to replace Nanladin as overseer of Annam with his assistant Zhang Tingzhen. The next year Zhang replaced Hulonghaiya as overseer while holding the prestigious title of Grant Master for the Court Precedence. Arriving in the Vietnamese capital ThÃÂng Long, Zhang delivered Kublai Khan's edict, but king Thánh Tông stood (rather than kowtowed) to receive it. Zhang accused the king of maintaining connections with the Song dynasty in Southern China, and threatened him with Yuan military forces â a million Yuan troops who were besieging Xiangyang "could reach ÃÂại Viá»Ât" in less than two months. According to Chinese sources, this scared the Vietnamese king and made him kowtow to the edict. The king nonetheless had more complaints which can be seen in his dialogue with Zhang. After few sentences, Trần Thánh Tông felt increasingly angry. Hence he ordered guards to draw their swords and surround Zhang to threaten him. Seeing this, Zhang untied his bow and sword and lay them down on the floor in middle of the hall, saying: "See what you can do to me!". The Vietnamese king and his guards were impressed with Zhang's courage.
In 1269, Trần Thánh Tông memorialized the Yuan court that the two Muslim merchants had died, so he would send two large elephants demanded by Huilonghaiya in the proper tribute year. In the next year, the Secretariat of the Yuan sent to the Vietnamese king a message, quoting the words from the Spring and Autumn Annals to chastise him for not "having kowtowed to the imperial edict; for having treated the emissary of the Son of Heaven (Kublai) improperly; for having presented bad-tasting medicine; and for having dishonest in the matter of the Muslim merchants." Trần Thánh Tông refused these accusations in his letter written in Classical Chinese to Kublai next year (1271). In the next two years, Kublai sent new overseers to ÃÂại Viá»Ât, demanded for searching the lost copper columns of Ma Yuan which erected after the Trung sisters' rebellion was suppressed in 43 AD, and once again wanted Trần Thánh Tông to be presented in Dadu in person. He refused.
In 1279, the Yuan dynasty decisively defeated the Song dynasty in the Battle of Yamen, which marked the end of the Song dynasty and began the total control of Kublai Khan over China. As a result, Kublai Khan began to expose his attempt to take over the southern countries like ÃÂại Viá»Ât or Champa. Aware of the situation, Thánh Tông and Nhân Tông began to prepare the military for the obvious and inevitable war while trying to maintain a flexible policy towards the Yuan dynasty. Prince Chiêu VÃÂn Trần NháºÂt DuáºÂt was appointed with the task of pacifying the revolt led by Trá»Ânh Giác MáºÂt in ÃÂàGiang by diplomatic means to keep the country stable before the war. With his knowledge of the minority people's language and culture, Trần NháºÂt DuáºÂt successfully accomplished his task in 1278; the Trần dynasty was hence free to deal with the threat from the north. In October 1282, Retired Emperor Trần Thánh Tông and Emperor Trần Nhân Tông gathered all members of the royal family, the Trần clan, and officials at the royal court in Bình Than to discuss the unavoidable war. Two prominent generals of the ÃÂại Viá»Ât army who were noticed on this occasion were Trần Khánh Dð, the former commander of the army but who was deprived of all titles after his guilt, and Trần Quá»Âc Toản, a marquis who was only sixteen years old. In 1283, Prince Hðng ÃÂạo Trần Quá»Âc Tuấn was appointed the commander-in-chief () of the ÃÂại Viá»Ât army, and the Retired Emperor and the Emperor began to hold military exercises with their generals and troops.
In December 1284, the second Yuan invasion of ÃÂại Viá»Ât began under the command of Kublai Khan's son Toghan. ÃÂại Viá»Ât was attacked from two directions, with Toghan himself commanding the infantry's invasion from the northern border while the Yuan navy under General Sogetu advanced from the southern border through Champan territory. At the beginning of the war, Thánh Tông and Nhân Tông ordered the army to retreat to avoid pressure from the Yuan force when Prince Chiêu Minh Trần Quang Khải commanded troops try to stop Sogetu's fleet in the Nghá» An Province. During this time, several high-ranking officials and members of the Trần royal family defected to Yuan forces, including Thánh Tông's own brother Prince Chiêu Quá»Âc Trần ÃÂch Tắc, and Trần Kiá»Ân, who was the son of Prince Ténh Quá»Âc Trần Quá»Âc Khang. For the safety of Thánh Tông and Nhân Tông's retreat, Princess An Tð was offered as a gift and a diversion for Toghan, while Marquis Bảo Nghéa Trần Bình Trá»Âng was captured and later killed in the Battle of ÃÂàMạc while defending the two emperors. At the southern border, Trần Quang Khải was also forced to retreat under the pressure of Sogetu's navy and the defection of the governor of Nghe An. Despite the repeated problems, the royal family and royal court of the Trần dynasty maintained their harmony and determination owing to favourable decisions and actions from Thánh Tông, Nhân Tông, Trần Quá»Âc Tuấn and Trần Quang Khải.
The critical situation of the Trần dynasty began to change after their victory at the Battle of Hàm Tá» in April 1285, where troops commanded by Trần NháºÂt DuáºÂt, Prince Chiêu Thành, Trần Quá»Âc Toản, and Nguyá» n Khoái were finally able to defeat Sogetu's fleet. On May 10, 1285 (in the lunar calendar), Trần Quang Khải fought a decisive battle at Chðáng Dðáng where Yuan's navy was almost destroyed; the balance on the battlefield tilted definitively in favour of the Trần dynasty. Ten days after Sogetu was killed, Emperor Nhân Tông and Retired Emperor Thánh Tông returned to the capital, ThÃÂng Long, on June 6, 1285 (in the lunar calendar).
In March 1287, the Yuan dynasty launched their third invasion of ÃÂại Viá»Ât. Unlike in the second attack, Prince Hðng ÃÂạo Trần Quá»Âc Tuấn, the commander-in-chief, affirmed that ÃÂại Viá»Ât's army could easily break the Yuan military campaign. Indeed, this invasion ended one year later with a disastrous defeat of the Yuan navy at the Battle of Bạch ÃÂằng on March 8, 1288 (in the lunar calendar). Besides Trần Quá»Âc Tuấn, other notable generals of the Trần dynasty during this time included Prince Nhân Huá» Trần Khánh Dð, who destroyed the Yuan navy's logistics convoy at the Battle of Vân ÃÂá»Ân, and General Phạm Ngà © Lão, who was responsible for ambushing Toghan's retreating troops.
In rewarding generals and mandarins Trần dynasty after the victory, Thánh Tông and Nhân Tông also reminded them to be cautious of the northern border. The Emperor also issued an order in which the family name of every defector from the Trần clan was changed to Mai â Trần Kiá»Ân, for instance, was renamed Mai Kiá»Ân. As the only prince from the Trần clan who defected, Trần ÃÂch Tắc was exempt from this requirement, but was referred to in historical accounts of the Trần dynasty by the name "Ả Trần" ('the woman named Trần'), implying that Trần ÃÂch Tắc was as cowardly as a woman.
Retired Emperor Trần Thánh Tông died on May 25, 1290 (in the lunar calendar), at the age of 50. He was buried in Dụ LÃÂng with the posthumous name Huyá»Ân công thá»Ânh ÃÂức nhân minh vÃÂn và © tuyên hiếu hoàng ÃÂế (çÂÂÃ¥ÂÂçÂÂå¾·ä»ÂæÂÂæÂÂæÂ¦å®£åÂÂçÂÂå¸Â).
Trần Thánh Tông had one consort, Empress Thiên Cảm Trần Thiá»Âu, the fifth daughter of his uncle Trần Liá» u. Thánh Tông's first son, Trần Khâm, was born on November 11, 1258 (in the lunar calendar), only eight months after the Emperor's enthronement; he was entitled as Crown Prince in December 1274. His second son, Prince Tá Thiên Trần ÃÂức Viá»Âp, was born in 1265. Trần Thánh Tông's only daughter was Princess Thiên Thụy, who married to Prince Hðng Và © Trần Quá»Âc Nghiá» n, son of Trần Quá»Âc Tuấn. She had an adulterous affair with General Trần Khánh Dð, which almost led to the latter's death by order of the Emperor. Princess Thiên Thụy and her younger brother Trần Nhân Tông died on the same day, November 3, 1308 (in the lunar calendar).
The Lê dynasty historian Ngô Sé Liên praised Trần Thánh Tông as one of the finest monarchs of the Trần dynasty, as not only a righteous ruler, but also a dutiful son, kind-hearted brother and father with sense of responsibility who was credited for the stability of both the royal family and the whole country. Thánh Tông's successful reign was the foundation for the subsequent long period of prosperity and peace in ÃÂại Viá»Ât. Moreover, like his brother Trần Quang Khải, Trần ÃÂch Tắc and Trần NháºÂt DuáºÂt, Trần Thánh Tông was a renowned scholar. Thánh Tông taught his princes with his own poems, and he also had a literary work named Di háºÂu lục. As a Confucian historian, Ngô Sé Liên did, however, sometimes criticize the Emperor for his devotion for Buddhism, which was seen as not being suitable for a person in a high position like him.
