Why were sudras important to ancient India?

Sudras were essential to ancient India as they constituted the lowest tier of the traditional Caste System, primarily serving as laborers, artisans, and service providers. They played a crucial role in the economy by supporting agricultural production and various crafts, thereby enabling the functioning of society. Their work allowed the higher castes to engage in religious and scholarly pursuits. Despite their lower social status, Sudras were vital for the sustenance and development of ancient Indian civilization.
