The Tang Dynasty lasted 22 generations, lasting 289 years. Together with the Han Dynasty, it is called one of the two powerful dynasties in the history of China. The Tang Dynasty (6 18-907) was one of the dynasties with the longest unification time and the strongest national strength in the history of China. 6 18 was founded by Li Yuan, and its capital is Chang 'an (Jin 'an).

In 907, Zhu Wen usurped the Tang Dynasty and the Tang Dynasty perished. The Tang Dynasty lasted for 289 years and had 20 emperors. The fame of the Tang Dynasty spread far and wide overseas, and it had contacts with countries in South Asia, West Asia and Europe. After the Tang Dynasty, China was called "the Tang people" overseas. Tang poetry, science and technology, culture and art are extremely prosperous and have the characteristics of diversification.

The territory of the Tang Dynasty was unprecedented. At its peak, the territory started from the Sea of Japan in the east, occupied by Annan in the south, the Aral Sea in the west and Lake Baikal in the north. It is the first unified dynasty in China since the Qin Dynasty that did not build the Great Wall of Hu.

After the Tang Dynasty conquered East Turkistan and Xue Yantuo, Emperor Tiandi was honored as Tiankhan by the four clans, and used the imprisonment system to recruit Turkic, Uighur, Tiele, Qidan, Mohong, Shiwei and other vassal states to attack the enemy, so that Japan, Nanzhao, Silla and Bohai could learn their own culture and system.

The economy, society, culture and art of the Tang Dynasty are characterized by diversity and openness. A large number of famous poets have emerged in poetry, calligraphy, painting and music, such as poet Li Bai, poet Du Fu, poet Bai Juyi, calligrapher Yan Zhenqing, painter Wu Daozi and musician Li Guinian. The Tang Dynasty accepted the exchange and study of various countries and formed an open and diverse culture.

Powerful military power is a distinctive military feature of the Tang Dynasty. China was unified in the Tang Dynasty, and warlords were separated in the late Sui Dynasty. When Emperor Taizong was in power, he conquered East and West Turkistan, Xue Yantuo, Gaochang, Koguryo, Baekje and other countries successively, and defeated Japanese reinforcements in the Battle of Baicunjiang, and recruited Hong, Tiele, Shiwei, Qidan and other ethnic groups to fight.

At that time, the military system, economy and scientific and technological advantages of the Tang Dynasty in Asia were the basis of these achievements.

During the reign of Emperor Xuanzong of the Tang Dynasty, the forces of the Tang Dynasty met forces from Arabia, and the emerging Sunnis believed in Islam. They met in Central Asian countries, including nine surnames, such as Zhaowu, Bolu and Tuhuoluo. As a result, China's forces withdrew from Central Asia because of the Anshi Rebellion. One after another, the separation of the provinces led to the economic depression in North China.

Among the many famous generals in the Tang Dynasty, foreign generals also occupied an important position, except for Xue, General, his son, Gao Pian and other Han generals in the twenty-four outstanding figures of Taishou and Lingyange.

The destruction of land equalization system and rent adjustment system led to the change of officers and men system into conscription system and recruitment system. The Anshi Rebellion and the expansion of cycling caused by the military system of the interim government could not resist the forces of our time.

The Tang Dynasty lost power militarily: there were vassal areas inside, and Uighur, Tubo and Nanzhao invaded the border outside. However, in the second year of Huichang in the late Tang Dynasty, Tang Jun destroyed the sip Department of Uighur, collected 7,000 accounts and killed nearly 90,000 prisoners. When the arrows were fired, the camels dived, and Wu Jie captured them and killed them.
