Why is the Han Dynasty divided into the Eastern Han Dynasty and the Western Han Dynasty? Are there any historical events?

Because the Eastern Han Dynasty and the Western Han Dynasty are two dynasties. However, the titles of the two dynasties were Han, but one was Chang 'an and the other was Luoyang, so for the sake of distinction, they were called the Eastern Han Dynasty and the Western Han Dynasty respectively.

The establishment of the Eastern Han Dynasty began with Wang Mang's new dynasty. The so-called long-term separatist regime, the late Western Han Dynasty, unprecedented intensification of social contradictions, at any time to breed uprisings. At this time, follwed began to reform. Reform inevitably infringes on the interests of local strongmen, and the reform measures are quite idealistic. In other words, the reform plan did not match the productivity at that time, was divorced from reality, and was difficult to implement, so social contradictions were not alleviated, but further intensified. Coupled with the continuous floods and droughts in recent years of Wang Mang's New Deal, farmers could not live any longer, and there was the Red Eyebrow Greenwood Uprising.

The era of competition has opened again. Liu Xiu is one of the best. He defeated Wang Mang's army, and later won the follow-up and support of Hebei local strongmen. Finally, he defeated other uprising troops and became emperor, in order to establish the Eastern Han Dynasty.

Liu Xiu is a descendant of the Han Dynasty, but like Liu Bei, compared with the royal orthodoxy, I don't know where it went. Like * * * in the Han Dynasty, it is estimated that everyone is surnamed Liu. But Liu, the capital, declared his uprising as an act to restore the Han Dynasty. As a result, other uprising troops were all disorderly parties, and he himself was a brave man who rehabilitated the Han Dynasty.

In this way, in order to prove the legitimacy of the regime, he forced himself to be the son of the Han family and named his country Han. In order to distinguish these two unrelated dynasties, later generations had to name one the Western Han Dynasty and the other the Eastern Han Dynasty.
