Wang Dao

In these capacities, he served as a crucial governing figure of the Eastern Jin Dynasty during its first decades, as well as the leading member of the prominent Wang clan of Langya.

It was at Wang's suggestion that Sima Rui slipped out of the capital Luoyang and stayed safe during most of the War of the Eight Princes in his Principality of Langye.

Under Wang Dao's counsel, Sima Rui personally visited He Xun (賀循) and Gu Rong (顧榮) and invited them to serve in his administration.

Around the time that Luoyang fell to Han-Zhao and Emperor Huai was captured (July 311), large numbers of refugees fled to Sima Rui's domain.

Before Emperor Ming's death in October 325, he made Wang Dao one of the officials he entrusted his four-year-old son Sima Yan with.

After Sima Yan took the throne (as Emperor Cheng), several officials who were named in Emperor Ming's will were put in charge—that included Wang Dao, Sima Yang (司馬羕) the Prince of Xiyang, Bian Kun (卞壼), Xi Jian, Yu Liang, Lu Ye (陸瞱), and Wen Jiao.

Wang stayed regent until his death in 339, and he was buried with great honors, including some ceremonies that were ordinarily reserved for emperors.
