Transition from Sui to Tang: Wang Shichong decisively defeats Li Mi at the Battle of Yanshi.
Transition from Sui to Tang
The transition from Sui to Tang (613–628), or simply the Sui-Tang transition, 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.
Wang Shichong
Wang Shichong, courtesy name Xingman (行滿), was a Chinese military general, monarch, and politician during the Sui dynasty who deposed Sui's last emperor Yang Tong and briefly ruled as the emperor of a succeeding state of Zheng. He first became prominent during the reign of Emperor Yang of Sui as one of the few Sui generals having success against rebel generals, and during Yang Tong's brief reign, he was able to defeat the rebel general Li Mi and seize Li Mi's territory. After becoming emperor, however, he was unable to withstand military pressure from Tang dynasty forces, forcing him to seek aid from Dou Jiande the Prince of Xia. After Dou was defeated and captured by the Tang general Li Shimin, Wang surrendered. Emperor Gaozu of Tang spared him, but the Tang official Dugu Xiude (獨孤修德), whose father Dugu Ji (獨孤機) had been executed by Wang, assassinated him.
Li Mi (Sui dynasty)
Li Mi, courtesy name Xuansui (玄邃), pseudonym Liu Zhiyuan (劉智遠), was a Chinese military general, monarch, poet, politician, and rebel. He was the leader of a rebel movement against the rule of the Chinese Sui dynasty. He initially was the strategist of the Sui general Yang Xuangan, who rebelled against Emperor Yang of Sui in 613 but failed. In 617, Li subsequently led a rebellion against Emperor Yang in his own right and killed Zhai Rang, seizing Zhai's troops.
