At the end of Sui Dynasty, the whole world stood together, and Tang Guogong Li Yuan took advantage of the situation to set up an army in Jinyang. In 6 18, he became emperor, established the Tang Dynasty, and made Chang 'an his capital. After Emperor Taizong succeeded to the throne, he initiated the rule of chastity and laid the foundation for the prosperous Tang Dynasty. Tang Gaozong inherited Zhenguan's legacy and initiated the "rule of eternal emblem". In 690, Wu Zetian changed the title to Zhou, and after the Dragon Revolution in 705, the title of Tang Dynasty was restored. After Emperor Xuanzong of the Tang Dynasty ascended the throne, he created a prosperous new century and reached the peak of the Tang Dynasty. At the end of Tianbao, the national population reached about 80 million. After the Anshi Rebellion, separatist regimes and eunuch dictatorship appeared one after another, and the national strength gradually declined. After the rule of Tang Xianzong Yuanhe Zhongxing, Tang Wuzong Huichang Zhongxing, and Tang Xuanzong Dazhong, the situation in the whole country became turbulent again. The peasant uprising that followed at the end of the Tang Dynasty destroyed the ruling foundation of the Tang Dynasty, and the power of the buffer region increased greatly. In 907 AD, Zhu Wen, the general of the buffer region, usurped the Tang Dynasty and the Tang Dynasty perished.
The territory of the Tang Dynasty was unprecedented. In its heyday, it rose from the Sea of Japan in the east, occupied Annan in the south, reached the Aral Sea in the west, and surpassed Lake Baikal in the north. After the attack and destruction by the East Turkistan and Xue Yantuo, Emperor Taizong was honored as Tiankhan by all ethnic groups in Siyi. In the Tang Dynasty, Turkic, Uighur, Tiele, Qidan, Mohong, Shiwei and other nationalities were imprisoned and surrendered to the enemy, while Japan, Nanzhao, Silla, Bohai and other vassal States were allowed to learn their own culture and system, resulting in the situation that all countries came to North Korea.
The Tang Dynasty accepted exchanges and studies from various countries, and its economy, society, culture and art showed the characteristics of diversification and openness. A large number of famous poets have emerged in poetry, calligraphy, painting and music, such as Li Bai, Du Fu, Bai Juyi, calligrapher Yan Zhenqing, painter Wu Daozi and musician Li Guinian.
The Tang Dynasty was one of the most powerful countries in the world at that time, with a well-known reputation and contacts with Asian and European countries. After the Tang Dynasty, China was called "the Tang people" overseas.
