Politics: The Sui and Tang Dynasties were the perfect period of centralization in China feudal society. The Sui Dynasty initiated the system of three provinces and six departments and the imperial examination system, and the Tang Dynasty further improved the system of three provinces and six departments. Clear division of labor, easy to improve administrative efficiency. The position of the top officials in the three provinces is equivalent to that of prime ministers, which is convenient for brainstorming and mutual restraint, avoiding the threat of excessive power to the monarch, thus better solving a pair of inherent contradictions in China feudal society-the contradiction of monarchical power, thus strengthening centralization.
The imperial examination system enabled people with low social status to participate in the political power, and the rulers could further attract scholars, which expanded the class foundation of feudal rule and also had an impact on the decadent aristocratic system since the Wei, Jin and Southern Dynasties. The perfection of these two systems ensured the stability of feudal politics and created conditions for economic development. However, another pair of inherent contradictions in feudal society-the contradiction between the central and local governments-has not been properly solved at this stage. Because Xuanzong of the Tang Dynasty set up a buffer region on the border, the local power expanded, which posed a serious threat to centralization, so the Anshi Rebellion broke out and the Tang Dynasty turned from prosperity to decline. However, after the Anshi Rebellion, the local separatist regime accelerated the decline of the Tang Dynasty and directly led to its demise.
Economically, the Sui and Tang Dynasties followed the system of equal land since the Northern Wei Dynasty, and the rulers of the Tang Dynasty even developed the tenancy system into a rent-and-rent tune. The biggest feature of this system lies in the setting of harmony, that is, silk or cloth can be used as corvee. The land equalization system enables farmers to obtain certain land, and the rent adjustment system ensures farmers' labor time. These two systems became an important guarantee for the economic prosperity of the Tang Dynasty.
However, with the development of feudal economy, land annexation intensified, and a large number of state-owned land was privatized, which made the land available to the government less and less, the land equalization system was destroyed, and the rent adjustment system could not be maintained, thus affecting the national fiscal revenue. In order to solve the financial difficulties. 780? The government of the Tang Dynasty implemented two tax laws in 1920, which changed the tax collection standard which was mainly based on manpower in the past, and was a major change in China's tax system. However, it did not restrict land annexation, so the class contradictions in the late Tang Dynasty were constantly sharp, which led to the peasant war. Source: www.examda.com.
Ethnic relations: The Sui and Tang Dynasties was an important development stage of China's unified multi-ethnic country, and ethnic relations were unprecedentedly prosperous, especially in the early Tang Dynasty, because it was a prosperous period of feudal society in China, with advanced political system, developed economy, and prosperous science, technology and culture. This provided a good foundation for the Han regime to develop ethnic relations, and at the same time, it also attracted all ethnic groups in the border areas, making them urgently demand to absorb the advanced culture of the Tang Dynasty and take the initiative to develop relations with the Tang government. For example, Songzan Gambu proposed to the Tang government. The national policy of the central government in the Tang Dynasty was also more cheerful, and it actively adopted various ways, such as direct jurisdiction, conferring titles and equal exchanges, to actively develop relations with neighboring nationalities.
Foreign relations: the Tang Dynasty was powerful and attractive to the outside world; Land and sea transportation is also relatively developed; The government also pursues an open foreign policy, which provides convenient conditions for the development of foreign relations. At this time, the Tang Dynasty had very close contacts with North Korea, Japan and other East Asian countries, and its influence on these countries and regions was not only reflected in the political and economic system, but also in urban architecture, writing, daily life customs and so on.
The impact on countries in West Asia and South Asia is mainly reflected in the economic and cultural aspects. It should be pointed out that the influence of Tang culture on foreign countries is far-reaching, but the influence of foreign culture on Tang culture is extremely obvious. Tang Wenhua is extensive and profound, which is based on absorbing the essence of foreign culture. The economies and cultures of all countries, regions and ethnic groups are mutually influential and complementary, and the status of all countries and ethnic groups is equal.
