Aryans' own society has formed three groups. The first group was a warrior group called Rajayana, which was later renamed Khshatriya. The second group is the priest group, called Brahman. The two groups fought for the political rights of Aryans. As a result, we are familiar with the fact that Brahman became the final winner. The third group of Aryans are agricultural and handicraft producers. They are Vedas. Many Indian aborigines were also brought into the Aryan social system and became sudra. The original source of sudra includes not only the conquered aborigines, but also the mixed-race descendants of Aryans and local aborigines. Vedas are usually farmers, merchants, craftsmen and landlords, while sudra is a farmer who works on a farm or in a handicraft workshop.

After the Aryans conquered, Aryans gradually established many social and religious systems and rules, which made the division of this class permanent. The caste system came into being, and the biggest feature of the caste system is stubbornness and stagnation, which will not be transformed between castes. It not only permanently fixed the status of all social classes, but also fixed their occupations, limiting social interaction and marriage among various castes.

Because the light skin of Aryan conquerors is in sharp contrast with the dark skin of local people, skin color is closely related to the caste system. Caste is actually called Varna, which means skin color. As time goes on, the skin color of Aryans is also changing. Even the skin of today's higher castes is often much darker than that of our yellow race in East Asia. In the west, there is a word that insults Indians, calling them "polished blacks", because although they are dark, they still retain the characteristics of white people such as thin lips and narrow noses, as if they had polished black people's thick lips and wide noses.

Aryan Sanskrit:? ry？ It is one of the three ancient nomadic peoples in the world (Asian-African nomadic people, Altai nomadic people, Indo-European nomadic people). Indo-European was used by ancient tribes in Caucasus and Central Asia. Historically, it is an ancient nation on the grassland in the southern Urals Mountains of Russia. Ancient Aryans migrated to the plains between Amu Darya and Syr Darya in Central Asia and settled down. These people are called Aryans-Punjabis. In about14th century BC, one of the Aryans, Punjabi, went south to the northwest of the South Asian subcontinent and was called Aryan-Punjabi-Indian, which was called Aryan in ancient Indian literature. Another Aryan-Punjabi entered the Iranian plateau and was called Aryan-Punjab-Iranian.

On the Iranian plateau, they merged with the ancient Aryans-Punjabis, forming later Persians, Medes, Skettians and others. In the South Asian subcontinent, they expelled the Das people from Dehlavi to the south, created the Vedic culture, established the caste system, and brought Aryan-Punjabi to India.
