Later Vedic Period or Painted Grey Ware Phase (1000 BC – 600 BC) During this time, the Aryans moved eastwards and occupied western and eastern UP (Kosala) and Bihar. Political structure: # Kingdoms like Mahajanapadas were formed by amalgamating smaller kingdoms. # King’s power increased and various sacrifices were performed by him to enhance his position. # Sacrifices were Rajasuya (consecration ceremony), Vajapeya (chariot race) and Ashwamedha (horse sacrifice). # The Sabhas and Samitis diminished in importance. Social structure: # The Varna system of social distinction became more distinct. This became less based on occupation and more hereditary. # The four divisions of society in decreasing social ranking were: Brahmanas (priests), Kshatriyas (rulers), Vaishyas (agriculturists, traders and artisans), and Shudras (servers of the upper three classes). # Women were not permitted to attend public assemblies like Sabhas and Samitis. Their position in society diminished. # Child marriages became common. Sub-castes based on occupation also emerged. Gotras were institutionalised. Economic structure: # Agriculture was the chief occupation. Industrial work like metalwork, pottery and carpentry work also was there. # There was foreign trade with far off regions like Babylon and Sumeria. Religion: # Prajapati (creator) and Vishnu (preserver) became important gods. # Indra and Agni lost their significance. Importance of prayers diminished and rituals and sacrifices became more elaborate. # The priestly class became very powerful and they dictated the rules of the rites and rituals. Because of this orthodoxy, Buddhism and Jainism emerged towards the end of this period.
