Emperor Mingyuan of Northern Wei ((北)魏明元帝) (392 – 24 December 423), Chinese name Tuoba Si (拓拔嗣), Xianbei name Mumo (木末), was an emperor of the Xianbei-led Northern Wei dynasty of China. He was the oldest son of the founding emperor Emperor Daowu. During his reign, Northern Wei's territory did not expand as much as it did under either his father's reign or the reign of his son Emperor Taiwu, but he helped the state stabilize over northern China, and started the tradition of meeting with important imperial officials to listen to their advice and make final decisions. He is generally regarded by historians to be an intelligent and rational ruler.
Early life
Tuoba Si was born in 392 after his father Tuoba Gui had founded Northern Wei in 386 but before he had conquered most of rival Later Yan's territory and claimed imperial title in 399. His mother was Tuoba Gui's favorite consort, Consort Liu, the daughter of the Xiongnu chief Liu Toujuan (劉頭眷). He was born at the capital Yunzhong (雲中, in modern Hohhot, Inner Mongolia.) He was Tuoba Gui's oldest son, and his father was said to be so pleased by this late arrival of a son that he declared a general pardon. (Based on Northern Wei's official history, Tuoba Gui would only be 21 at this point; this might be further evidence corroborating the alternative version of his life history.)
As Tuoba Si grew, he was said to be a wise and kind young man, whose actions were all in accordance with proper protocol. In contrast, his oldest younger brother Tuoba Shao (拓拔紹) was a frivolous and violent young man, and often received punishment from Emperor Daowu, and Tuoba Si tried to correct his brother's behavior by rebukes, but this made Tuoba Shao angry at him. In 403, Tuoba Gui, by this point emperor (as Emperor Daowu), created him the Prince of Qi. In 409, Emperor Daowu was intent on creating Tuoba Si crown prince, but based on the Tuoba tradition that when an heir is decided upon, his mother must be put to death, Emperor Daowu forced Consort Liu to commit suicide. Either before or after he did so, he summoned Tuoba Si to explain to him that this tradition was also in accordance with Emperor Wu of Han's rationale to put his favorite concubine, Consort Zhao (Emperor Zhao of Han's mother) to death, to avoid overly great maternal influence on a young emperor. After Tuoba Si left his father's presence, because of the affection that he had for his mother, he mourned greatly. Hearing this, Emperor Daowu summoned him back to the palace—and, because Emperor Daowu, in his late reign, often displayed great paranoid and violent tendencies, the new crown prince's attendants suggested that he not go to the palace but hide in the country. Tuoba Si agreed and did so, fleeing the capital Pingcheng, where Emperor Daowu had moved the capital in 398.
Meanwhile, Emperor Daowu had, because of Tuoba Shao's crimes, imprisoned Tuoba Shao's mother Consort Helan and planned to execute her. Consort Helan sent her son a message, asking him to save her. In response, Tuoba Shao assassinated Emperor Daowu and then tried to take over as emperor, and he tried to seize the troops. Tuoba Si, upon hearing this news, returned to Pingcheng but hid himself, while trying to gather supporters gradually. Tuoba Shao tried to seek him out to kill him, but the imperial guards gradually shifted to Tuoba Si's side, and the imperial guards arrested Tuoba Shao and presented him to Tuoba Si. Tuoba Si executed Tuoba Shao, Consort Helan, and Tuoba Shao's associates. He then took the throne as Emperor Mingyuan.
Early reign
Emperor Mingyuan, contrary to his father's dictatorial style, instituted a council of eight officials to advise him on all important decisions, with the intent to hear different opinions and then take informed actions. The council mostly constituted of ethnic Xianbei from his tribe, but also included Han and other ethnicities. This became a tradition that was followed by his descendants as well. However, while he was known as being much more lenient than his father, he also did not tolerate wrongdoing on his advisors' part. For example, in 413, one of his key advisors, Tuoba Qu (拓拔屈) the Marquess of Yuancheng, suffered a major defeat at the hands of Xia forces, and then, once demoted to governorship of Bing Province (并州, modern central and southern Shanxi), failed to carry out his task competently, and Emperor Mingyuan executed him.
