How did the caste system come to be in India?

The Caste System in India has its roots in ancient social and economic hierarchies, as documented in texts like the Rigveda around 1500 BCE. Initially, it was based on the division of labor among four main varnas: Brahmins (priests), Kshatriyas (warriors), Vaishyas (traders), and Shudras (laborers). Over time, this system became more rigid, influenced by factors like regional variations, religious beliefs, and economic changes, leading to the complex and stratified social structure seen today, where thousands of jatis (sub-castes) exist. The caste system has been perpetuated through social customs, legal frameworks, and colonial policies, despite efforts for reform and social justice.
