Yuwen Tai - During Emperor Gong's Reign

During Emperor Gong's Reign

In spring 554, while on a diplomatic mission to Liang (now with Xiao Yi as its undisputed emperor—as Emperor Yuan), the Western Wei official Yuwen Renshu (宇文仁恕, probably Yuwen Tai's relative but relationship is unclear) was slighted by Emperor Yuan, who treated Northern Qi's ambassador with far greater respect. Emperor Yuan then further aggravated the situation by sending an impolite letter to Yuwen Tai demanding that the borders be redrawn in accordance with old borders. Yuwen made the comment, "Xiao Yi is the type of person that, as said in proverbs, 'One who has been abandoned by heaven cannot be revived by anyone else.'" Yuwen Tai therefore began to prepare attacking Emperor Yuan at his headquarters of Jiangling (江陵, in modern Jingzhou, Hubei), as Emperor Yuan had made Jiangling his capital and declined to move back to the old capital Jiankang. The Western Wei general Ma Bofu (馬伯符), formerly a Liang general, secretly revealed the attack plans to Emperor Yuan, but Emperor Yuan did not believe Ma and took minimal precautions.

In winter 554, under Yuwen Tai's orders, Western Wei forces, commanded by Yu Jin (于謹), who was assisted by Yuwen Tai's nephew Yuwen Hu and Yang Zhong, launched a major attack on Liang. Emperor Yuan initially did not take reports of the Western Wei attack seriously, and while he summoned his major generals Wang Sengbian and Wang Lin from afar, he himself took little defensive or evasive actions. Yu quickly descended on Jiangling and put it under siege. Soon, Emperor Yuan surrendered, and Western Wei forces gave him to Xiao Cha to be executed. Western Wei created Xiao Cha the Emperor of Liang (as Emperor Xuan) and gave him the Jiangling area in exchange for his old domain of Xiangyang area, which Western Wei took control directly. (However, the rest of Liang did not recognize Emperor Xuan, and soon recognized a rival candidate for the throne supported by Northern Qi, Emperor Yuan's cousin Xiao Yuanming.) Most residents of Jiangling were seized as slaves, although eventually most of them were released by Yuwen after he was persuaded to do so by one of the captives, the Liang official Yu Jicai (庾季才).

Around the near year 556, after Tujue's Mugan Khan Ashina Qijin thoroughly crushed Rouran's last khan Yujiulü Dengshuzi, Yujiulü Dengshuzi fled to Western Wei. Ashina Qijin demanded the execution of Yujiulü Dengshuzi, and Yuwen Tai, fearing a Tujue attack, turned Yujiulü Dengshuzi and 3000 of his followers to the Tujue ambassadors, who slaughtered them.

Also around the new year 556, Yuwen Tai promulgated a new government structure, dividing the government into six ministries, based on the Zhou Dynasty model. (This structure was initially devised by Su Chuo, and after Su Chuo's death, Yuwen had it further revised by Lu Bian (盧辯).) He also had Tuoba Yu the Prince of Huai'an submit a request, and then have Emperor Gong formally approve the request, to have all imperial princes reduced in rank to dukes, in accordance with the Zhou tradition.

In spring 556, Yuwen was pondering the issue of succession. His wife Princess Fengyi had one son, Yuwen Jue, but his oldest son, Yuwen Yu, was born of his concubine Lady Yao, and was married to the daughter of one of his chief generals, Dugu Xin. On the advice of Li Yuan (李遠), who argued that the son of a wife always had precedence over the son of a concubine, Yuwen Tai made Yuwen Jue his heir apparent.

in fall 556, while Yuwen Tai was on a tour of the norther provinces, he became ill at Qiantun Mountain (牽屯山, in modern Guyuan, Ningxia). He summoned his nephew Yuwen Hu to Qiantun and entrusted the affairs of the state as well as his sons to Yuwen Hu. He soon died, and Yuwen Jue took over his titles, while Yuwen Hu took the reins of the state, and under Yuwen Hu's tutelage, Yuwen Jue soon took the throne from Emperor Gong, ending Western Wei and establishing Northern Zhou.
