| In a long period, when historians studied the empress dowager Lv and the Lv families, they always considered them as a group who was the relative of the empresses or empress dowagers. But the writer of this thesis considers that they were also a group person who has rendered outstanding service to his country.The thesis has four sections.The first section talks about the historical background of the early Han dynasty. At that time, there were three powers in the government. How about the relation among these powers, and how about the relation between the government and these three powers? That is what the thesis wants to say. fn this section, the nature of the Lv clique was discussed, and the members of the Lv clique were list too.The second section explains what the Lv had done in early Han dynasty. As we all known, empress dowager Lv controlled the country. At that time, some palace political affairs appeared, and the palace power organization completed.The third section mostly proves the truth of the "Zhu Lv coup d'etat". The truth is that the Lv clique never wanted to usurp the royal power from the Liu royalty. In fact, the government officials and Liu royalty wanted to get more power, so they launched a palace war. Because the Lv clique were defeated in that palace war, they were slandered to be usurpers.The last section gives some reasons about those strange things which were discussed in the thesis. |
