The Tang Dynasty was the most prosperous feudal society in China. Try to analyze the reasons for the rise, prosperity and decline of the Tang Dynasty.

The reason why the Tang Dynasty was so prosperous: 1. Political development, especially political unity and stability.

2. Economic development is mainly handicraft technology and urban commercial development.

3. Enlightened and harmonious ethnic policy

4. An open and compatible foreign policy

5. The influence of the foundation of the previous generation, especially the culture of Wei, Jin, Southern and Northern Dynasties, on the culture of the Tang Dynasty.

By summarizing the development of politics, economy, ethnic relations and foreign relations in the Tang Dynasty, this paper analyzes the reasons for the cultural prosperity in the Tang Dynasty.

Close ethnic cultural exchanges (emphasis: 1. The government's open and compatible ethnic policy; 2. All ethnic groups get along with each other on an equal footing, and each absorbs the excellent characteristics of national culture. Historical facts: The Tibetan medical book Four Medical Codes represents the enrichment of minority medicine to China culture, and the music and dance in the Tang Dynasty absorbed the characteristics of minority music and dance. )

Absorb foreign civilizations (emphasis: 1. The government's open and compatible foreign policy; 2. The Tang Dynasty had frequent contacts with some countries in Asia, Europe and even Africa, and absorbed excellent elements of foreign cultures. Historical facts: The art of Mogao Grottoes has absorbed the sub-cultures of Central Asia and South Asia, and the music and dance have absorbed the styles of neighboring countries. )

Inherit and carry forward traditional culture (emphasis: 1. Historical development must be based on the efforts of predecessors; 2. Absorb and learn from Wei and Jin culture. Historical facts: gunpowder invention, astronomical calendar achievements, architectural style, poetic characteristics, etc. )

Reasons for the demise of the Tang Dynasty

Economically: serious land merger (root cause);

Politically, there was a serious party struggle in the imperial court;

The attack of peasant uprising (the root cause is land merger);

Institutionally; Our system makes local forces stronger than the central government;

Militarily: Western minority attacks.

As for the authorities' inability to deal with land annexation, this is due to the nature of the feudal system. Under the condition of underdeveloped productive forces, farmers can't bear the losses of farming alone (such as natural disasters, locust plagues, etc.) and must rely on the landlord class. Under the feudal system, the contradiction between farmers and landlords can only be reconciled, but not solved. The government of the late Tang Dynasty had no energy to deal with these thorny problems, which led to its demise.
