What was the most powerful dynasty in the history of China? Considering the military economy and people's life

The Tang Dynasty (6 18-907) was one of the dynasties with the longest unification time and the strongest national strength in China feudal society. 6 18 was founded by Li Yuan, and its capital is Chang 'an (Jin 'an). Luoyang in the east and Taiyuan in the north. In 627, after Li Shimin ascended the throne, he initiated the "Zhenguan Rule". After Tang Gaozong, Wu Zetian was named Wu Zhou in the Zhou Dynasty after the Tang Dynasty, and recovered the title of Datang after the Dragon Revolution in 705. After Li Longji ascended the throne, Xuanzong of the Tang Dynasty was politically clear, economically powerful and militarily powerful, and all ethnic groups came to the DPRK in succession, creating a prosperous "Kaiyuan Shi Sheng". After the Anshi Rebellion, the national strength gradually declined. In 907, Zhu Wen usurped the Tang Dynasty and the Tang Dynasty perished. Since then, China has entered the Five Dynasties and Ten Kingdoms period. The Tang Dynasty lasted 274 years (including 289 years in five states) 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. The culture of the Tang Dynasty is eclectic, accepting all ethnic groups and religions, exchanging and integrating, and becoming an open international culture. Tang poetry, science and technology, culture and art are extremely prosperous and have the characteristics of diversification. The vast territory of the Tang Dynasty reached its peak in the 7th century, when the oasis in Central Asia was ruled by the Tang Dynasty. Its largest scope extends to Luofu State (now Hejing, Vietnam) in the south, Xuanzang State (now Angara River Basin, Russia) in the north, Rest State (now Bukhara, Uzbekistan) in the west and Gobe State (now Tonghua, Jilin) in the east, with a land area of10.76 million square kilometers, or12.4 million square kilometers. After the mid-Tang Dynasty, the territory of Mobei and the Western Regions fell to the size of China at the end of the Tang Dynasty, but the Hetao area still existed. In its heyday, the Tang Dynasty made great achievements in culture, politics, economy and diplomacy. It was one of the prosperous times in China's history and one of the world powers at that time. Silla, Koguryo, Baekje, Bohai and Japan were greatly influenced by the Tang Dynasty in political system and culture. In the first half of the Tang Dynasty, the social economy rose and the culture was advanced, which was a period when China exported its culture and technology to neighboring countries in history. The inclusive social atmosphere has also provided an unprecedented communication and integration environment for all ethnic groups living in Serbia since the Sixteen Countries in Wuhu, and they have also learned a lot of foreign civilizations in the process. In the second half of the Tang Dynasty, China was in a historical transition period. The reform of soil, salt, iron and tax system marks the slow change of society, the growth of separatist forces in buffer regions and the formation of neighboring nation States, which have had a far-reaching impact on the history of China in the past thousand years.
