The founding emperor of the Western Han Dynasty (also known as the pre-Han Dynasty and the pre-Han Dynasty) was Liu Bang, whose capital was Chang 'an, who enjoyed the country for more than 200 years. The founding emperor of the Eastern Han Dynasty was Liu Xiu, the grandson of Liu Bang IX, the great ancestor of the Han Dynasty. As far as the blood relationship of the supreme ruler is concerned, the Western Han Dynasty and the Eastern Han Dynasty are in the same strain.
This law was promulgated during the reign of Emperor Wu of the Han Dynasty, so the title of hereditary vassal will gradually shrink from generation to generation. Liu Xiu is so lucky. Liu Xiu's grandfather could be a captain at that time, and his father became a county magistrate. Therefore, of course, his father was regarded as the official rank of Zhongzong in the Western Han Dynasty, which is also recognized.
But when Liu Xiu came here, there was no official to do it for him, and their royal branch had lost the qualification of hereditary nobility. From this point of view, it is indeed a family and related by blood, but it is really not the closest kind.
Differences between the Western Han Dynasty and the Eastern Han Dynasty
First, the capital of the Western Han Dynasty is Chang 'an, and the capital of the Eastern Han Dynasty is Luoyang, one in the east and the other in the west, so there is a difference between the Eastern Han Dynasty and the Western Han Dynasty.
Second, the enfeoffment system was implemented in the early years of the Western Han Dynasty, and then centralization strengthened the central government's control over local affairs, insisting that the central government dominated local regional affairs and cracked down on local strongmen, while the Eastern Han Dynasty relied on local strongmen's policies for governance, which led to the occurrence of the situation that the central government had no right, the local power was strong, and the consorts' exclusive rights were serious in the later period.
Thirdly, the Western Han Dynasty carried out an active foreign exchange policy and the basic strategy of conquering Xiongnu, including Zhang Qian's feat of going to the West and Wei Qing and Huo Qubing's war against Xiongnu.
The Eastern Han Dynasty has always followed the foreign policy of the Western Han Dynasty, but it is also different from the Western Han Dynasty. The two have different starting points. The Western Han Dynasty expanded its territory in order to expand its territory and conquer ethnic minorities, while the Eastern Han Dynasty fought against ethnic minority regimes in order to protect its territory.
