What social system did Aryans introduce to India?

The Aryans introduced the Caste System to India, which structured society into hierarchical groups based on occupation and social status. This system divided people into four main categories: Brahmins (priests and scholars), Kshatriyas (warriors and rulers), Vaishyas (traders and agriculturists), and Shudras (laborers and service providers). Over time, this rigid social stratification became deeply entrenched, influencing social interactions and individual opportunities for centuries. The caste system has had lasting effects on Indian society, shaping cultural and social dynamics to this day.
