This paper discusses the political, economic and cultural changes in medieval India from the 3rd century to the 7th century.

A: During the transition from slave society to feudal society in the 3rd to 7th centuries, India experienced the rule of Gupta dynasty and imperial palace in the Middle Ages, and its political, economic and cultural changes mainly included the following aspects:

(1) Politics

The king of the Anti-Japanese War established a hierarchical bureaucratic system of "severe punishment and severe law". Although the king of the Anti-Japanese War was famous for his "benevolent governance", his criminal law was quite harsh. The king is the highest owner of the country's land, occupying most of the land and distributing it to temples, officials and nobles. Farmers have become feudal dependent farmers, and they must pay rent and pay taxes to feudal lords and be under their jurisdiction. The caste system has undergone major changes. In the Vedas and sudra, there are groups engaged in different occupations, namely, Kauti and Kauti. Their internal occupations are hereditary and they are not allowed to get married, which hinders the development of India to some extent.

(2) Economy

The establishment of the feudal system promoted the development of agriculture, and there was a bumper harvest of grain everywhere. The industry and commerce of coastal ports and cities closely related to foreign trade continued to prosper, but the industry and commerce and monetary economy of many ancient cities in the Ganges Valley began to slump, and there was a scene of "fewer and fewer people in the city", which on the other hand reflected the occlusion of India's feudal economy in the early Middle Ages.

(3) Culture

Attach importance to the use of religion for political rule, tend to Mahayana Buddhism, adopt a tolerant religious policy, and Buddhism and Hinduism are compatible. During this period, Xuanzang, a monk in the Tang Dynasty, went west to seek dharma, which promoted the cultural exchanges between the Chinese and Indian people. During 64 1 ~ 647, the anti-Japanese king sent diplomatic envoys to the Tang Dynasty many times, and Emperor Taizong also sent diplomatic missions such as Wang Xuance to visit India four times, which opened the political exchanges between the two countries and laid the foundation for friendly relations and cultural exchanges between China and India.
