and Sima Daozi the Prince of Langye. He died soon thereafter, and Sima Yao assumed the throne as Emperor Xiaowu.
During Emperor Xiaowu's reign
As the emperor's only surviving brother, Sima Daozi was in an honored position. In 380, when he was just 16, he was offered the position of prime minister, but he declined. In 383, he finally accepted the title while the empire was preparing for a showdown with the powerful rival

, thus guaranteeing the dynasty's continued survival, he soon came into a power conflict with
Xie An, who had served as Emperor Xiaowu's regent ever since Emperor Xiaowu's ascension; this conflict was aggravated by Xie An's son-in-law
Wang Guobao (王國寶), whose cousin was Sima Daozi's wife and whom Xie disfavored, who therefore retaliated by slandering Xie before Emperor Xiaowu and Sima Daozi. Emperor Xiaowu therefore began to listen to Xie less, and in 385, Xie volunteered to lead an army and leave the capital to avoid further conflict with Sima Daozi. When Xie died later that year, Sima Daozi became the head of the government under Emperor Xiaowu, who entrusted his brother with most important affairs of state.
Both Emperor Xiaowu and Sima Daozi were described to be spending much of their times with drinking and feasting, rather than with important affairs of state. A number of politicians who wanted power gathered around Sima Daozi and flattered him, causing him to be less and less deferential to the emperor. He was also known for being obsessed with gathering wealth and for extravagance in living—including constructing an artificial hill in the back of his mansion, an excessively expensive and difficult task. Emperor Xiaowu eventually became angry about the situation, and he commissioned the well-known officials
Wang Gong Wang Gong () (d. 899) was a warlord late in the Chinese dynasty Tang Dynasty, who controlled Baoyi Circuit (保義, headquartered in modern Sanmenxia, Henan) from 887, when he succeeded his father Wang Chongying, to his death in 899.

Huan Xuan (桓玄) (369 – 19 June 404), courtesy name Jingdao (敬道), nickname Lingbao (靈寶), formally Emperor Wudao of Chu (楚武悼帝), was a Jin Dynasty warlord who briefly took over the imperial throne from Emperor An of Jin and de ...
the Duke of Nan Commandery—as at one feast where Sima Daozi invited Huan Xuan as a guest, after Sima Daozi became drunk, he made the statement, "Was it not true that when Huan Wen became old, he planned treason?" Huan Xuan was so struck by the statement that he fell prostrate on the ground, fearing that Sima Daozi would kill him, and from this point he bore a grudge against the prince.

[According to Sima Yao's biography in ''Book of Jin'', Sima Daozi was made Prince of Kuaiji and Sima Dewen was made Prince of Langya on the ''gengyin'' day of the 11th month of the 17th year of the ''Taiyuan'' era of Yao's reign.

, was suffocated by her in his sleep. However, with the crown prince being developmentally disabled and with Sima Daozi being foolish and unthinking, no one investigated his death. Crown Prince Dezong took the throne as Emperor An; Sima Daozi, as the emperor's uncle, served as regent.
As Emperor An's regent
Sima Daozi, as regent, greatly trusted Wang Guobao and his cousin Wang Xu (王緒) because of their flattery, and his regency quickly developed a reputation for being corrupt and incompetent. Wang Gong, whom Emperor Xiaowu entrusted with the armies of the northeastern part of the empire, considered starting a rebellion to overthrow Wang Guobao and Wang Xu. In 397, Wang Guobao and Wang Xu suggested to Sima Daozi that the armies that Wang Gong and Yin Zhongkan were in charge of be reduced; Wang Gong and Yin, who was in command of the western provinces, in response, mobilized their forces and declared that Wang Guobao and Wang Xu should be executed. Sima Daozi, in fear, forced Wang Guobao to commit suicide and executed Wang Xu. Wang Gong and Yin then retreated. From this point on, Sima Daozi trusted no one but his teenaged

Sima Yuanxian, and entrusted the capital guards to Sima Yuanxian. He also gave military commands to his distant relatives Sima Shangzhi (司馬尚之) the Prince of Qiao and Sima Shangzhi's brother Sima Xiuzhi, as well as Wang Yu (王愉), in 398.
The giving of a military command to Wang Yu oddly drew a reaction from Wang Gong and Yin—as Wang Yu's command included four commanderies originally under the command of Yu Kai (庾楷), who became angry and managed to persuade Wang Gong and Yin that Sima Daozi's intention was to act against them as well. They therefore rose again, but Sima Daozi was able to persuade Wang Gong's general
Liu Laozhi (劉牢之), who was in command of the elite Beifu Forces (北府兵), to suddenly turn against Wang Gong, capturing and executing him. Yin, hearing of Wang Gong's death, was in fear but considered proceeding anyway—and Sima Daozi, under suggestion by Huan Xuan's cousin Huan Xiu (桓脩), managed to cause dissension between Yin and his generals Huan Xuan and
Yang Quanqi (楊佺期) by offering Huan and Yang key posts; although Huan and Yang nominally remained Yin's allies, Yin was forced to withdraw his troops, and from that point on no longer posed a major threat, as his domain had now been divided into three, with Huan and Yang each given a third.
In late 398, the magician Sun Tai (孫泰), a friend of Sima Yuanxian's, who had gathered great following due to his magic, was exposed as planning a plot to take over the central government, and Sima Daozi ordered Sima Yuanxian to trap Sun Tai and execute him. Sun Tai's nephew

Island and planned revenge.
In summer 399, Sima Yuanxian, wanting even greater power, took an opportunity when his father was very drunk to have Emperor An issue an edict transferring Sima Daozi's authorities to Sima Yuanxian. When Sima Daozi awoke from his stupor, he was enraged, but after that point his power became extremely limited, even though he nominally remained regent.
Later in 399, Sun En launched his rebellion and captured most of the eastern empire for a while, until Liu Laozhi led his Beifu Forces and defeated Sun, forcing him to flee back to Zhoushan. Still, the only region remaining under central government control was now laid waste.
In 401, Sima Yuanxian, apprehensive of Huan Xuan (who had by then defeated and executed Yin and Yang, taking over the entire western empire), declared Huan a renegade and launched a campaign against him. However, he relied on Liu's troops, and Liu, not trusting his good intentions, again turned sides and joined Huan, and in 402 the capital
