Emperor Huai of Jin spouse Empress Liang Lanbi
As Prince of Yuzhang and crown prince
Sima Chi was one of the youngest sons of Sima Yan, the founding emperor of Jin, by his concubine Consort Wang.  Just prior to Emperor Wu's death in May 290, he was created the Prince of Yuzhang on 22 December 289.  During the early stages of the War of the Eight Princes during his developmentally disabled brother Sima Zhong's reign, unlike the other princes fighting for power, Prince Chi did not get himself in political or military matters, but spent his time studying history.
In late 304, when Emperor Hui was forcibly taken from the capital Luoyang to Chang'an, then under the control of the regent Sima Yong Prince of Hejian, Prince Chi was forced to accompany the emperor.  In February 305, when his more ambitious brother Sima Ying the crown prince was demoted back to Prince of Chengdu by Sima Yong, Prince Chi was created crown prince to replace him.  He was initially going to decline the honor, believing that his nephew Sima Qin (司馬覃) the Prince of Qinghe and one-time crown prince should be returned to that position, but was persuaded to accept by his associate Xiu Su (脩肅).  Later, after Sima Yue the Prince of Donghai defeated Sima Yong in 306, Crown Prince Chi accompanied Emperor Hui and returned to Luoyang.
In January 307, Emperor Hui was poisoned.  (Most historians believe that Sima Yue ordered the murder, but there is no conclusive evidence.)  Emperor Hui's wife, Yang Xianrong, believing that she would not be honored as empress dowager if her brother-in-law inherited the throne, tried to have Sima Qin declared emperor; she was rebuffed by Sima Yue, however, and Crown Prince Chi succeeded to the throne as Emperor Huai.  Emperor Huai honored her with the title "Empress Hui," but not empress dowager.  He created his wife Crown Princess Liang Lanbi empress.Family
