- In the Rig Vedic period, 'Bali' was an offering, often voluntary, made to deities or priests. - However, in the later Vedic period (roughly 1000-600 BCE), the concept of 'Bali' evolved. It became a compulsory tribute or tax collected by the king from his subjects. - This transition reflects the development of a more formalized state structure with a king asserting greater authority and needing revenue.
