Taizong of Tang – One of the Greatest Emperors in Chinese History

Tai Tai Zong - Li Shimin

Taizong of Tang, also known as Li Shimin, was one of the most prominent emperors of the Tang Dynasty, ruling from 626 to 649 AD. He was known for his military prowess, political acumen, and cultural achievements and is widely regarded as one of the greatest emperors in Chinese history.

Background and Rise to Power

Li Shimin was born in 598 AD, the second son of Li Yuan, a prominent general of the Sui Dynasty. In 617 AD, Li Yuan led a rebellion against the Sui Dynasty, and Li Shimin played a key role in his father’s military campaigns. When Li Yuan declared himself emperor of a new dynasty, the Tang Dynasty, in 618 AD, Li Shimin was appointed as the prince of Qin, one of the Tang Empire’s provinces.

In 626 AD, Li Shimin launched a coup against his own father, accusing him of being too lenient and corrupt. With the support of other members of the royal family and his own military forces, Li Shimin successfully overthrew his father and became the new emperor of the Tang Dynasty. This coup is known as the Xuanwu Gate Incident, and it is considered one of the most significant events in Chinese history.


As emperor, Li Shimin implemented reforms that helped strengthen the Tang Dynasty and consolidate its power. He created a new system of government that was more centralized and efficient, with a network of officials and administrators appointed based on their merit rather than their family connections. He also reformed the military, creating a new system of conscription and training that made the Tang army one of the most formidable in the world.

Under Li Shimin’s leadership, the Tang Dynasty expanded its territory and influence, conquering neighboring kingdoms and establishing tributary relationships with other countries. He also encouraged cultural and artistic development, patronizing poets, scholars, and artists and commissioning numerous public works, including the famous Tang Grand Canal.

One of Li Shimin’s most notable accomplishments was establishing a diplomatic relationship with the Western Turkic Khaganate, a powerful nomadic confederation controlling much of Central Asia. Through a combination of military and diplomatic means, Li Shimin was able to establish a stable relationship with the Western Turks, which allowed the Tang Dynasty to expand its trade networks and influence in the region.


Li Shimin’s legacy as one of the most extraordinary emperors in Chinese history is largely due to his military, political, and cultural achievements. His military conquests and reforms helped to establish the Tang Dynasty as one of the most powerful and enduring in Chinese history, while his political and administrative reforms laid the foundation for a more efficient and effective system of government.

Li Shimin’s cultural legacy is perhaps less well-known, but no less significant. He was a patron of the arts and literature, and many of the greatest poets and writers of the Tang Dynasty flourished under his patronage. He was also a great builder, commissioning numerous public works and engineering feats, including the famous Tang Grand Canal, which connected China’s two major river systems and helped to facilitate trade and commerce.
