Luo Yi

Luo Yi (Chinese: 羅藝) (died 627), known during service to Tang Dynasty as Li Yi (李藝), courtesy name Ziyan (子延) or Ziting (子廷), was a Sui Dynasty official who rose against the rule of Emperor Yang of Sui and occupied the modern Beijing region. He subsequently submitted to Emperor Gaozu of Tang and was created the Prince of Yan and granted the imperial surname of Li. He subsequently, in the struggle between Emperor Gaozu's sons Li Jiancheng the Crown Prince and Li Shimin the Prince of Qin, joined Li Jiancheng's faction. After Li Shimin killed Li Jiancheng in 626 and forced Emperor Gaozu to yield the throne to him (as Emperor Taizong), Li Yi was fearful, and he rebelled against Emperor Taizong in 627. He was soon defeated and killed.

Luo Yi was said to be intelligent, self-confident, and capable in battle, but unkind.

Luo's was said to be strict in his discipline of soldiers, but he himself was arrogant even toward Li. Li often rebuked him, and he therefore resented Li.

By 616, nearby Zhuo Commandery (涿郡, roughly modern Beijing) was constantly under pillaging attacks by agrarian rebels, as Emperor Yang had stored much military supplies and placed many soldiers at Zhuo Commandery for his campaigns against Goguryeo, and nearby Linshuo Palace (臨朔宮) contained much imperial treasure. The military officers in charge of defending the city, Zhao Shizhu (趙什住), Helan Yi (賀蘭誼), and Jin Wenyan (晉文衍) were all unable to stop the pillaging raids, but Luo often battled these agrarian rebels and prevailed, earning him greater reputation than the others. Zhao, who was in overall command, greatly suspected Luo. Luo, who considered rebelling against Sui rule, incited his soldiers by telling them:
