Where did the cast system come from?

The Caste System in India has its origins in ancient Hindu society, primarily detailed in texts like the Rigveda, which categorized people based on their occupations and roles in society. Initially, it was a flexible system with four main varnas: Brahmins (priests), Kshatriyas (warriors), Vaishyas (traders), and Shudras (laborers). Over time, these categories became more rigid and complex, evolving into the hereditary caste system we recognize today, influenced by social, economic, and political factors throughout history. The system has been challenged and reformed, especially in modern times, but continues to impact Indian society.
