 The "aryas" are renamed "vis" or Vaishya (meaning the members of the tribe) and the new elite classes of Brahmins (priests) and Kshatriyas (warriors) are designated as new "varnas".The Shudras were not only the erstwhile "dasas" but also included the aboriginal tribes that were assimilated into the Aryan society as it expanded into Gangetic settlements.There is no evidence of restrictions regarding food and marriage during the Vedic period.
