司馬遹
In 323, Emperor Yuan died. In 326, Consort Zheng also died, and because, as Prince of Langya, Sima Yu was not permitted by law to mourn his mother, he, at age six, requested another title by which he could. His nephew Emperor Cheng (Emperor Ming's son), himself then a young child, permitted it, and created him the Prince of Kuaiji. As he grew in age, he was given a progression of higher and higher posts, although without actual power.
