Since Huo Kuang had been designated as a minister by Emperor Wu-Ti to assist his son, he, following the policies set up by the late Wu-Ti period, had confirmed the Han's administration policy, suppressed the conspiracy of rebellion from the antagonists, and established the status of his governing the national affairs. After the death of the Emperor Chao-Ti who hadn't had sons, Huo Kuang had acclaimed Chang-Yi as the Emperor but unthroned him soon. After that, he had acclaimed Hsuan-Ti as the Emperor. Emperor Hsuan-Ti had dared not to govern the Han by himself because Huo Kuang had had the power and influence to acclaim and unthrone the emperor. The entire Huo Family hadn’t been exterminated until the reveal of the Queen Hsu had been poisoned by Miss Huo after the death of Huo Kuang. This article is discussing the process of Huo Kuang's fighting for the power from Chao-Ti, Chang-Yi to Hsuan-Ti; the contribution to the Han politics from his whole life and the reason of the extermination of the entire Huo's.
