Emperor Daowu of Northern Wei - Late Reign

Late Reign

In the last few years of Emperor Daowu's reign, he became increasingly harsher in his treatment of his officials. For example, in 406, as he planned the expansion of Pingcheng with intent to make it into an impressive capital, he initially had his official Mo Ti (莫題), an accomplished civil engineer, plan the city's layout, but over a relatively minor issue where Mo was not very careful, ordered Mo to commit suicide—and then used Mo's layout anyway. He also made increasing visits to Chaishan Palace (豺山宮, in modern Shuozhou, Shanxi), often spending months there at a stretch. Other key officials that he killed during this period included his cousin Tuoba Zun the Prince of Changshan, Yu Yue, Monalou Ti (莫那婁題), and Tuoba Yi the Prince of Wei.

In 407, Northern Wei and Later Qin entered into a peace treaty, returning previously captured generals to each other. This would have a disastrous consequence on Later Qin, however, as Liu Bobo, then a Later Qin general, became angry because his father Liu Weichen had been killed by Northern Wei, and therefore rebelled, establishing his own state Xia. However, he spent much more of his energy conducting guerilla warfare against Later Qin, gradually sapping Later Qin's strength, and did not actually conduct warfare against Northern Wei.

By 409, Emperor Daowu, who was said to be under the effect of poisonous substances given him by alchemists, was described to be so harsh and paranoid in his personality that he constantly feared rebellion, particularly because fortunetellers had been telling him that a rebellion would happen near him. He occasionally would not eat for days, or would not sleep overnight. He often mumbled about his past accomplishments or defeats, and he suspected all of his officials. Sometimes when officials made reports to him, he would suddenly think of their past faults and punish or even kill them. Occasionally, when others would behave even slightly inappropriately, he would be so angry that he would kill them personally and display their bodies outside the palace. The entire government came under a spell of terror. The only persons immune from this treatment were said to be the minister Cui Hong and his son Cui Hao, who were said to avoid the disaster by never offending or flattering the emperor—both of which could have brought disaster.

In fall 409, Emperor Daowu resolved to create Tuoba Si crown prince. Because of the Tuoba traditional custom of executing the designated heir's mother, he ordered Tuoba Si's mother Consort Liu to commit suicide. He explained his reasons to Crown Prince Si, who, however, could not stop mourning for his mother, and Emperor Daowu became very angry, and he summoned the crown prince. Crown Prince Si, in fear, fled out of Pingcheng.

At this time, however, Emperor Daowu would suffer death at another son's hand. When he was young, when he had visited Helan tribe, he saw his maternal aunt (Princess Dowager Helan's sister), who was very beautiful, and he asked to have her as a concubine. Princess Dowager Helan refused—but not under the rationale that it would be incest, but rather that the younger Lady Helan had already had a husband and was too beautiful—citing a saying that beautiful things were often poisonous. Without Princess Dowager Helan's knowledge, he assassinated the younger Lady Helan's husband and took her as a concubine, and in 394 she bore him a son, Tuoba Shao (拓拔紹), whom he later created the Prince of Qinghe. Tuoba Shao was said to be a reckless teenager, who often visited the streets in commoner disguises, and often robbed travelers and strip them naked for fun. When Emperor Daowu heard this, he punished Tuoba Shao by hanging him upside down in a well, only pulling him out as he neared death. In fall 409, Emperor Daowu had an argument with Consort Helan, and he imprisoned her and planned to execute her, but it was dusk at the time, and he hesitated. Consort Helan secretly sent a messenger to Tuoba Shao, asking him to save her. At night, Tuoba Shao, then 15, entered the palace and killed Emperor Daowu. The next day, however, the imperial guards arrested and killed Tuoba Shao and Consort Helan, and Tuoba Si took the throne as Emperor Mingyuan.
