The Rig Vedic Period did not show indications of the caste system; the foundation for the Hindu social system came later.

Characteristics of the social system in the Rig Vedic Period:

- Absence of classes: The social system in the Rig Vedic Period was characterized by an absence of rigid social classes. Society was more egalitarian compared to later periods, and there was no fixed hierarchy based on birth or occupation. People were mainly classified based on their occupation and social status was not as rigidly defined as in later periods.

- Caste system: The caste system as we know it today did not exist in the Rig Vedic Period. While there were different occupations and social groups, these were not hereditary and individuals had the freedom to choose their profession based on their skills and interests.

- Varna system: The Rig Vedic Period did have a rudimentary form of the Varna system, which classified society into four main categories - Brahmins (priests and scholars), Kshatriyas (warriors and rulers), Vaishyas (traders and farmers), and Shudras (laborers). However, these categories were not as rigidly enforced as in later periods and individuals could move between varnas based on their abilities and actions.

- Equality among all classes: There was a sense of equality among all classes in the Rig Vedic Period. People were valued more for their skills and contributions to society rather than their birth or social status. This sense of equality helped foster a more harmonious society where individuals were judged based on their actions rather than their background.

Overall, the social system in the Rig Vedic Period was characterized by a relative lack of social hierarchy and a greater emphasis on individual merit and contributions to society.
