He was created crown prince in 387 and ascended the throne in 397. Because of his disability, the actual power was controlled by his uncle, Sima Daozi, Prince of Kuaiji. During his reign, regents and warlords dominated the Jin regime. Revolts by various governors also ravaged the land. From 398 to 403, there were constant revolts and civil war campaigns.

He began to indulge himself in women and heavy drinking and paid little attention to affairs of state, instead leaving matters to corrupt eunuchs. In this way, he effectively became the first emperor in Han history to encourage corruption. He also trusted his wife Empress Yan Ji and her family deeply, despite their obvious corruption. At the same time, droughts ravaged the country while peasants rose up in arms. In 125, Emperor An died while travelling to Nanyang. He was only 31.

Content:  Empress Wang Shen'ai (王神愛) (384–412), formally Empress Anxi (安僖皇后, literally "the peaceful and careful empress") was an empress of Jin Dynasty (266–420). Her husband was the developmentally disabled Emperor An. Wang Shen'ai was the daughter of the official Wang Xianzhi, the son of the famed official and calligrapher Wang Xizhi. Her mother Princess Xin'an was the daughter of Emperor Jianwen, making her and her husband cousins. In 396, while he was still crown prince under his father Emperor Xiaowu, they married, and she became crown empress. She was 12, and he was 14. As he was described to be so developmentally disabled that he could not speak or dress himself, or express whether he was full or hungry, it was unlikely that their marriage was consummated; in any case, they had no children.

With the warlord Liu Yu as the actual power, Jin destroyed Southern Yan and Later Qin, greatly expanding its territory. However, with Liu Yu up in the north, the renegade governor of Guang Province (廣州, modern Guangdong and Guangxi), Lu Xun, rebelled and threatened the capital city Jiankang, before Liu Yu returned and crushed the revolt. In 419, Emperor An was strangled under the order of Liu Yu and replaced with his brother Emperor Gong, who would be the last emperor of the dynasty, before Liu Yu would take the throne and establish the Liu Song Dynasty.

As an insurance measure, Emperor He's wife, Empress Dowager Deng, kept Prince Qing's wife and 12-year-old son (Prince Hu). When Emperor Shang died later in 106, the officials largely wanted to make Emperor Shang's brother, Prince Sheng (劉勝) of Pingyuan, emperor. However, Empress Deng had initially denied Prince Sheng the throne because she believed him to be frequently ill; she was concerned that he would bear a grudge against her. At her insistence, Prince Hu ascended the throne as Emperor An.

He therefore became resolved to kill Emperor An, and he tried several times to have Emperor An's servants poison him, but because Emperor An's brother Sima Dewen continuously attended to him, the servants had no chance to poison him. However, around the new year 419, Sima Dewen was himself ill and had to be at his house. Liu Yu's assassin Wang Shaozhi (王韶之) then took the opportunity to kill Emperor An—according to Zizhi Tongjian, by twisting clothes into a rope and then using it to strangle Emperor An. Liu Yu then made Sima Dewen emperor (as Emperor Gong).
