Liu Yao
In fall 316, Liu Cong sent Liu Yao to attack Chang'an, and Liu Yao captured it and the Jin emperor, sending him to Pingyang, thus ending the so-called Western Jin Dynasty (although Jin would not actually end, as its Prince of Langye, Sima Rui, then safely south of the Yangtze River at Jiankang would claim the title "Prince of Jin" in 317 and declare himself emperor in 318, thus continuing Jin as the so-called Eastern Jin Dynasty). Liu Cong created the former Jin emperor the Marquess of Huai'an, and he created Liu Yao the Prince of Qin and put him in charge of the western empire.
