Liu Yao
After Liu Yuan declared himself the Prince of Han in 304, creating Han Zhao state and effectively declaring independence and war on Jin, he made Liu Yao a major general. During Liu Yuan's reign, Liu Yao engaged in many campaigns against Jin forces and often was victorious, although he, like other Han Zhao generals, had difficulty permanently holding cities that he captured. In 307, along with his cousin Liu Cong and Wang Mi, he attacked Luoyang, but was repelled. They were again foiled in 309. Liu Yao was probably created the Prince of Shi'an in 309, when Liu Yuan declared himself the emperor.
