汉文帝
After Empress Dowager Lü's death in 180 BCE, it was alleged that the Lü clan plotted to overthrow the Liu dynasty, and Liu Xiang the King of Qi (Emperor Gaozu's grandson) rose against the Lüs. Before the central government and Qi forces engaged each other, the Lü clan was ousted from power and destroyed by a coup led by the officials Chen Ping and Zhou Bo at Chang'an. Although Liu Xiang had resisted the Lüs, he was passed over to become emperor because he had mobilized troops without permission from the central government and because his mother 's family possessed the same ambitious attitude as the Lüs. Consort Bo, the mother of Liu Heng, King of Dai, was considered to possess a noble character, so her son was chosen as successor to the throne; he is known posthumously as Emperor Wen of Han (r. 180–157 BCE).
