Liu Yao
In early 319, Shi sent a delegation to pay tribute to Liu Yao. Liu Yao was very pleased, and made Shi the Prince of Zhao. However, subsequently, Liu Yao became suspicious that Shi was about to rebel, so killed Shi's lead delegate. Shi became angry, and later that year declared independence under the title of Prince of Zhao. (Because Liu Yao, also in 319, changed the formal name of his state from Han to Zhao, Shi's state became known as Later Zhao.)
