Liu Cong
Late in Liu Cong's reign, Liu Cong grew increasingly cruel and extravagant, as well as increasingly trusting eunuchs and the treacherous official Jin Zhun. In 318, as Liu Cong grew ill, he summoned Liu Yao and Shi Le to be regents for his son Liu Can, but both Liu Yao and Shi declined, perhaps not wishing to contest the authorities of Jin Zhun, whose daughters had sway with Liu Cong and Liu Can as their wives. Subsequently, when Liu Cong died later that year and Liu Can succeeded to the throne, Jin Zhun became powerful and overthrew Liu Can, slaughtering all members of the imperial Liu clan in the capital Pingyang (平陽, in modern Linfen, Shanxi). In the massacre, Liu Yao lost his mother Lady Hu, brother, and (he thought at the time) his son and heir Liu Yin. (However, unknown to his father, Liu Yin fled but was captured by or sold to a tribe named Heiniyuju (黑匿郁鞠) as a slave.)
