The Rig Veda Caste System refers to the social hierarchy established in ancient India, as outlined in the Rig Veda, one of the oldest sacred texts of Hinduism. This system classifies society into four main groups: the Brahmins (priests and scholars), Kshatriyas (warriors and rulers), Vaishyas (merchants and landowners), and Shudras (laborers and service providers), which illustrates the early foundations of social stratification in Indian culture and its continuity and change over time in a globalized world.
