What were the main occupations of the Aryans before coming to India? How has their life changed after their conquest of Hindustan?

The conquerors adopted the techniques of agriculture from them, and they began to speak the language of the Aryans.

– In the north of India, small states were formed headed by the leaders of the Aryans.

– Members of the third varna, formerly free community members, fell into dependence and began to be considered as part of the fourth, lower, sudra varna – servants.

– Then the inhabitants were divided into even smaller groups by occupation. These groups – castes existed along with the varnas. There were castes of blacksmiths, weavers, fishermen, merchants, etc. Some people occupied such a low position that they did not belong to any caste (untouchable). They lived outside the villages so as not to desecrate the rest of the inhabitants.

– Later, the rights and obligations of each varna were recorded in Manu. In the first place were the brahmanas. In fact, however, the kshatriyas were often much more powerful than the brahmanas. There were rich people among artisans or farmers, and even in the sudras varna. On the contrary, there were many impoverished brahmanas leading a beggarly life.
