The history of the Tang Dynasty began in 6 18, when Tang Gaozu Li Yuan proclaimed himself emperor, and ended in 907, when Zhu Wen, Emperor of the Later Liang Dynasty, usurped the Tang Dynasty in 289. It can be roughly divided into several periods, roughly bounded by the Anshi Rebellion. At the beginning of the Tang Dynasty, the national strength was strong. In the period of Emperor Taizong, the national strength gradually recovered, defeating the strong enemy East Turkistan. Emperor Taizong was honored as "Tiankhan" and realized the rule of Zhenguan.

During the period of Tang Gaozong, he defeated powerful enemies such as West Turkistan and Koguryo, and established the rule of Yonghui. After Tang Gaozong's death, Wu Zetian reached its peak in People's Republic of China (PRC)'s founding week in 690. Until 705, Tang Zhongzong was restored by the Dragon Revolution, and the Tang Dynasty was also restored. It was not until Emperor Xuanzong of the Tang Dynasty succeeded to the throne that the politics dominated by women completely ended. Xuanzong of the Tang Dynasty entered its heyday, which was the second peak and turning point of the Tang Dynasty. During the Kaiyuan period, Emperor Xuanzong of the Tang Dynasty got rid of the disadvantages of the previous dynasty, became politically enlightened, and conquered all countries in the world. This is the so-called Kaiyuan Prosperity. By the time of Tianbao, politics was gradually chaotic. In 755, An Shi Rebellion broke out, and the Tang Dynasty turned from prosperity to decline.

In the middle Tang Dynasty, under the influence of internal and external troubles such as the invasion of Heshuo and Tubo towns, the eunuch's autocratic power and the dispute between cattle and Li, the Tang Dynasty went into decline. In the meantime, although Tang Xianzong's Yuanhe Zhongxing, Tang Wuzong's Huichang Zhongxing and Tang Xuanzong were temporarily ruled by Dazhong, they failed to eradicate the internal and external troubles of the Tang Dynasty.

In the late Tang Dynasty, because of political corruption, civil strife broke out in the late Tang Dynasty. Among them, the Huang Chao Rebellion destroyed the economy in the south of the Yangtze River, completely disintegrated the economy in the Tang Dynasty, and led to the separatist regime in the country. Finally, the Tang Dynasty was controlled by Zhu Quanzhong. He forced to move the capital to Luoyang, and in 907 he forced to go to Zen, and Tang died. Zhu Quanzhong Liang Jianguo, known as Hou Liang in history, entered the Five Dynasties and Ten Kingdoms period.
