Lý Thái Tông (chữ Hán: 李太宗; 29 July 1000 – 3 November 1054), personal name Lý Phật Mã, posthumously temple name Thái Tông, was the second emperor of the Lý dynasty, ruled Đại Việt from 1028 to 1054. He was considered the most successive Vietnamese emperor since the tenth century.
Lý Phật Mã was born in 1000 in Hoa Lư, Ninh Bình, during the reign of king Lê Hoàn, when his father Lý Công Uẩn was an official of the royal court. His mother was Lê Thị Phất Ngân, daughter of Lê Hoàn. When he was nine, Lý Công Uẩn became the new ruler of Đại Việt and moved the capital from Hoa Lư to Thăng Long. In 1020, as crown prince, Phật Mã was marching his army south through Thanh Hóa, he encountered the spirit of Mount Trống Đồng, which promised to help his campaign. Phật Mã successfully invaded Champa, killed the Cham commander, and destroyed half his army. After his father's death, Phật Mã claimed that the Spirit of Mount Trống Đồng, or the Mountain of the Bronze Drum (Thần Núi Đồng Cổ), which also inhabited a shrine at Thăng Long.
Lý Phật Mã ascended the throne in 1028. At the beginning of his reign, Thái Tông relied mostly on his father's officers to put down an uprising by two of his brothers contesting his accession, and personally led an expedition against a third rebellious brother at Hoa Lư.When his rule became more secure, Thái Tông started to demonstrate his unconventional style of governing. He promoted one of his favorite concubines to royal status. He rejected his officials' advice and plowed the land himself during the spring plowing ceremony.The king ignored convention and promoted a favourite concubine to royal status, thereby provoking a rebellion, which he crushed. He reorganized administration on the borders and built ocean-going junks. He apparently attempted to reform the system of justice and prisons at Thăng Long by placing it under the protection of the cult of a tenth-century hero. He ignored the objections of his advisers and insisted on personally conducting the spring ploughing ceremony. In 1039, Thái Tông had a serious discussion with his official about whether a good government depended upon strong personal leadership or a sophisticated institution. In the end, he accepted his officials' opinion and started to reform the government. In the same year he captured the leader Nong Quanfu of a rebellious clan in the northern mountains and publicly executed them at Thăng Long, publishing an edict full of self-righteous pride and indignation.In 1041 Thái Tông had statues cast of the Buddha Maitreya and two irrigation gods; the latter may again imply the emergence of Confucian associations between the monarchy and agricultural organization. In 1042 Thái Tông created a new code, called the Minh Đạo laws. Inspired by the Tang Code in China, these new laws were written by officials charged by Phat Ma to'deliberate about what was suitable to the contemporary age. The Minh Đạolaw book has not survived, but nine edicts dated within a few months of its publication have survived. Also in the same year, Nùng Trí Cao, the leader of the Nung clan in Cao Bằng province, proclaimed the state of Dali (大历). Because of his efforts, the Vietnamese captured him and held at Thăng Long for several years. In the next year, the Vietnamese court first time used the term nho thần (Confucianist scholar), referring to court officials whom the king ordered to "compose a rhyming narrative" in order to publicize his achievement of an "extraordinary supernatural event".In 1044, Thái Tông with his army invaded Champa by seaborne. After sailed 950 km across the sea, the Vietnamese fleet attacked Champa and the Cham king, Jaya Simhavarman II, was killed. The amount of the plunder was considerable, included 5,000 captives, trained elephants, gold, jade, and other treasures. The Cham captives settled in Nghệ An, lived in Cham-style villages and either became personal servants to the royal elite or laboured for religious establishments. They also contributed to the construction of religious buildings, indicated by thousands of bricks from Ba Đình which bear Cham script. Taxes were reduced, foreign merchants were accommodated, markets were opened in the mountains.In 1048, Nùng Trí Cao again rebelled and proclaimed the state of Heavenly South. Thái Tông attacked Nùng Trí Cao and only succeed in pushing him into the Song China's territories.In 1049, having dreamed of Avalokiteśvara seated on a lotus, he ordered the construction in Thăng Long of the One Pillar Pagoda, which survived in twentieth-century Hanoi.Starting around 1049, Thái Tông became less occupied with worldly affairs. He began to seek solutions of life through religion. He died in 1054 and a few months before his death, he transferred the governing job to his son Lý Nhật Tôn (Lý Thánh Tông). The succession went much smoother than the one in 1028 and proved the success of Thái Tông's institutional reform.
Lý Phật Mã was a devout Mahayana Buddhist since youth age. In 1040 he ordered silversmiths to decorate more than 1,000 statues and more than 1,000 paintings of Buddha. Thái Tông engaged with the Buddhist community more directly than did his father. Interacting with a variety of monks, he sought to honoured their varied opinions, including those emanating from India and China. At one point, the king held an vegetarian feast and state:
Huệ Sinh, a monk of distinguished local family whom the king had brought from a mountain north into the capital, made this reply in verse:
Dharma is originally like non-Dharma
Neither existent nor non-existent
If one knows the truth,
The sentient beings and Buddha are one.
How great the Moon over Lanka!
Empty, empty, the boat that crosses the ocean
If one knows emptiness, by mean of
that emptiness one realizes being,
Free to go everywhere in samadhi.
Thái Tông followed the monk's view, and Huệ Sinh became the court teacher. In the process, this monk composed inscriptions for a number of major temples in Tiên Du and Vũ Ninh areas north of the capital (which none of these temples survived). Thái Tông also brought the spirit cults into the capital. He was particularly close to the cult of the spirit of the Mountain of Bronze Drum from the southern territory of the Viet mandala. In front of this spirit, the king had courtiers swear their yearly blood oath of allegiance.
