Emperor Taizong of Tang, previously Prince of Qin, personal name Li Shimin, was the second emperor of the Tang dynasty of China, ruling from 626 to 649. He is traditionally regarded as a co-founder of the dynasty for his role in encouraging Li Yuan, his father, to rebel against the Sui dynasty at Jinyang in 617. Taizong subsequently played a pivotal role in defeating several of the dynasty's most dangerous opponents and solidifying its rule over China.

Xue Rengao was regarded as a fierce general but overly cruel, and he was only emperor for three months before he was forced to surrender to the Tang dynasty general Li Shimin and was executed.
The transition from Sui to Tang (613–628) was the period of Chinese history between the end of the Sui dynasty and the start of the Tang dynasty. The Sui dynasty's territories were carved into a handful of short-lived states by its officials, generals, and agrarian rebel leaders. A process of elimination and annexation followed that ultimately culminated in the consolidation of the Tang dynasty by the former Sui general Li Yuan. Near the end of the Sui, Li Yuan installed the puppet child emperor Yang You. Li later executed Yang and proclaimed himself emperor of the new Tang dynasty.

The military history of the Sui and Tang dynasties encompasses the period of Chinese military activity from 581 to 907. Although the Sui dynasty (581–618) preceded the Tang (618–907), it was extremely short lived, ending in 618. The two dynasties share many similar trends and behaviors in terms of military tactics, strategy, and technology. It can therefore be viewed that the Tang continued the Sui tradition, or that the Sui set the precedent for the Tang dynasty.
