the Tang Dynasty
The Tang Dynasty was the unified Central Plains dynasty in China history after the Sui Dynasty, with 2/kloc-0 emperors and enjoyed the dynasty for 289 years. 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. During the Xuanzong period of the Tang Dynasty, Kaiyuan flourished, which made the Tang Dynasty reach its heyday. 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 greatly increased the power of the buffer region. The emperor became the object of contention among warlords. The Tang Dynasty existed in name only. In 907, Zhu Wen, the general of the buffer region, usurped the Tang Dynasty and the Tang Dynasty perished.
