the Prince of Qin, he sided with Li Jiancheng and often advocated drastic actions against Li Shimin, including assassination. In 626, Li Shimin, fearing that Li Jiancheng and Li Yuanji were about to kill him, laid an ambush for them at Xuanwu Gate outside the palace and killed them. Li Shimin then effectively forced Emperor Gaozu to yield the throne to him (as Emperor Taizong).

Chen Shanyi (陳善意) tried to get him to change his ways, but he had his guards batter her to death. In spring 619, when his assistant Yuwen Xin (宇文歆) reported this to Emperor Gaozu, Emperor Gaozu temporarily removed him from his post. Less than a month later, however, with the people of Taiyuan petitioning to have Li Yuanji kept in charge, Emperor Gaozu restored him. (The traditional historians allege that Li Yuanji pressured the people into petitioning Emperor Gaozu.) In summer 619, Liu Wuzhou launched an attack on the Taiyuan region, and Li Yuanji sent the general Zhang Da (張達) to resist Liu, despite Zhang's protestations that the army given him was too small to resist Liu. When Zhang was in fact defeated, he surrendered to Liu and served as Liu's guide in subsequent attacks. Liu soon put Taiyuan under siege, and while Li Yuanji initially repelled him, Liu was soon back and again had Taiyuan under siege. In fall 619, Li Yuanji fled with his wife and concubines back to Chang'an, and Liu captured Taiyuan, moving his capital from Mayi (馬邑, in modern

Subsequently, when Emperor Gaozu had the government mint new coins, there were strict prohibitions against minting by any other persons, except that Li Shimin and Li Yuanji were each granted the right to have three mints and Pei Ji was granted the right to have one mint. Later that year, when Dou's general Liu Heita rose in resistance to Tang rule and took over all of Dou's former territory, Li Shimin and Li Yuanji were sent against him. Li Shimin defeated Liu in spring 622, forcing Liu to flee to Eastern Tujue. Subsequently, they attacked another rebel leader,

Role in the rivalry between Li Jiancheng and Li Shimin

Meanwhile, an intense rivalry had developed between Li Jiancheng, who as the oldest son was Emperor Gaozu's

. Li Yuanji supported Li Jiancheng in this rivalry, as he believed that if Li Jiancheng became emperor, Li Jiancheng would create him crown prince. Since their mother Duchess Dou had died in 614, the fact that Li Jiancheng and Li Yuanji had better relations with Emperor Gaozu's favored young

s than Li Shimin did take a notable importance, since those concubines helped rehabilitate Li Jiancheng's standing before Emperor Gaozu, causing him to no longer consider making Li Shimin crown prince instead, as he considered at one point.

), Li Jiancheng and Li Yuanji engaged him at Guantao (館陶, in modern Handan as well), crushing him. Liu fled north toward Eastern Tujue, but was ambushed and captured by his own official Zhuge Dewei (諸葛德威), who delivered him to Li Jiancheng. Li Jiancheng executed Liu. China was by this point almost completely unified by Tang. At one point, Li Yuanji tried to persuade Li Jiancheng to have Li Shimin assassinated when Li Shimin was visiting Li Yuanji's mansion, but Li Jiancheng, not having the heart to kill a brother, stopped Li Yuanji from doing so. In 624, Li Jiancheng requisitioned a number of soldiers from the general Li Yi the Prince of Yan, to supplement his guard corps, against Emperor Gaozu's regulations. When this was revealed to Emperor Gaozu, Emperor Gaozu rebuked Li Jiancheng and exiled his guard commander Keda Zhi (可達志). When, subsequently, Li Jiancheng nevertheless requested the commandant at Qing Prefecture (慶州, in modern

Li Jiancheng briefly flirted the idea of occupying Chang'an and not accepting the order, but eventually reported to Renzhi Palace to request forgiveness. Emperor Gaozu put him under arrest. When Yang heard this, Yang rebelled, and Emperor Gaozu, after promising Li Shimin that he would be made crown prince, sent Li Shimin to attack Yang.

), a suggestion that Li Jiancheng, Li Yuanji, and the chancellor Pei Ji agreed with. Li Shimin opposed, however, and the plan was not carried out. Meanwhile, Li Shimin himself was sending his confidants to Luoyang to build up personal control of the army there. After an incident in which Li Shimin suffered a severe case of food poisoning after feasting at Li Jiancheng's palace—an event that both Emperor Gaozu and Li Shimin apparently interpreted as an assassination attempt—Emperor Gaozu considered sending Li Shimin to guard Luoyang to prevent further conflict, but Li Jiancheng and Li Yuanji, after consulting each other, believed that this would only give Li Shimin an opportunity to build up his personal power there, and therefore opposed it. Emperor Gaozu therefore did not carry out the plan.


Death

By 626, Li Shimin was fearful that he would be killed by Li Jiancheng, and his staff members

and Cheng Zhijie (程知節), from Li Shimin's staff. Zhangsun, who remained on Li Shimin's staff, continued to try to persuade Li Shimin to attack first. In summer 626, Eastern Tujue was making another attack, and under Li Jiancheng's suggestion, Emperor Gaozu, instead of sending Li Shimin to resist Eastern Tujue as he first was inclined, decided to send Li Yuanji instead. Li Yuanji was given command of much of the army previously under Li Shimin's control, further troubling Li Shimin, who believed that with the army in Li Yuanji's hands, he would be unable to resist an attack. Li Shimin had Yuchi summon Fang and Du back to his mansion secretly, and then on one night submitted an accusation to Emperor Gaozu that Li Jiancheng and Li Yuanji were committing adultery with Emperor Gaozu's concubines. Emperor Gaozu, in response, issued summonses to Li Jiancheng and Li Yuanji for the next morning, convening the senior officials Pei Ji, Xiao Yu, and Chen Shuda to examine Li Shimin's accusations. As Li Jiancheng and Li Yuanji approached the central gate leading to Emperor Gaozu's palace, Xuanwu Gate (玄武門), Li Shimin carried out the ambush he had set. He personally fired an arrow that killed Li Jiancheng. Subsequently, Li Yuanji tried to kill Li Shimin, but Yuchi killed Li Yuanji instead during the struggle. Li Shimin's forces entered the palace and, under the intimidation of Li Shimin's forces, Emperor Gaozu agreed to create Li Shimin crown prince, and two months later passed the throne to him (as Emperor Taizong). Li Yuanji's five sons were all executed as well. Emperor Taizong also took Li Yuanji's wife Princess Yang as a concubine. Li Yuanji was initially posthumously reduced to commoner rank. After Emperor Taizong took the throne, he posthumously created Li Yuanji the Prince of Hailing, with the unflattering
