He Jin
Despite the machinations of Jian Shuo (a eunuch and close aide of Emperor Ling) to put Liu Xie on the throne, Empress He and her brother, General-in-Chief He Jin, succeeded in making Liu Bian emperor; Liu Bian is historically known as Emperor Shao. As the mother of the reigning emperor, Empress He became empress dowager, while Empress Dowager Dong became grand empress dowager. The empress dowager and grand empress dowager started vying for influence in court politics; their respective pillars of support, He Jin and Dong Zhong, were also locked in a power struggle. Grand Empress Dowager Dong contemplated getting Dong Zhong to help her eliminate He Jin. When Empress Dowager He heard about it, she informed He Jin and another brother of hers, He Miao (何苗). They decided to take preemptive action against the grand empress dowager.
