How were people placed in the caste system?

In traditional Indian society, individuals were placed in the Caste System primarily based on their birth, which determined their social status, occupation, and duties. The system is generally divided into four main categories: Brahmins (priests and scholars), Kshatriyas (warriors and rulers), Vaishyas (traders and agriculturists), and Shudras (laborers and service providers). Additionally, there are numerous sub-castes, reflecting regional and community variations. This hereditary system often dictated social interactions and opportunities, reinforcing a rigid social hierarchy.
