At the end of Qin Dynasty, the peasants revolted, and after Liu Bang overthrew the Qin Dynasty, he was named Hanwang. Chu and Han fought for hegemony, and Liu Bang defeated Xiang Yu and proclaimed himself emperor to establish the Han Dynasty, with Chang 'an as its capital, known as the Western Han Dynasty in history. Because he was named Hanwang by Xiang Yu, he took it? Han? As a national title, people later called it the Han Dynasty. The Chinese nation has been called the Han nationality since the Han Dynasty, which also made great achievements in the field of science and technology. For example, Cai Lun improved papermaking and became one of the four great inventions in China. Zhang Heng invented the seismograph and the armillary sphere.
Liu Bang, Emperor Gaozu of Han Dynasty, established the Western Han Dynasty, with Chang 'an as its capital, also known as the former Han Dynasty; Later historians did not recognize the legitimacy of the New Dynasty and the Xuanhan Dynasty, so they generally incorporated them into the history of the Han Dynasty. Liu Xiu, Emperor Guangwu of Han Dynasty, established the Eastern Han Dynasty with Luoyang as its capital, also known as the later Han Dynasty. The Western Han Dynasty and the Eastern Han Dynasty are collectively referred to as the Han Dynasty. During the Three Kingdoms period, the regime established by Emperor Liu Bei, Emperor Zhaolie of the Han Dynasty, still took Han as the country name, which was called "West Shu" in history.
The Han Dynasty was the first golden age in the history of China's development, and it was during this period that the Han nationality got its name. Because of its high level of civilization, the Han nationality has always been in an advantageous position among the fraternal nationalities in China, which is the result of historical development and natural formation. Liu Bang's successors are Liu Ying, Liu Heng, Liu Qi, Liu Che, Liu Fuling, Liu He, Liu Xun, Liu Shuang, Liu Ao, Liu Kang, Liu Xin, Liu Jie, Liu Ying, Wang Mang, Liu Xuan, Liu Sheng, Wang Chang, Liu Yong, Liu Bi, Lu Fang and Liu Xiu. Since the Han Dynasty, although the name of the dynasty has changed, the status of the Han nationality as the main ethnic group in China has never changed.
