As society became more decentralized, local rulers and elites gained more influence, leading to the development of new castes and the strengthening of existing ones. This period also witnessed the emergence of regional cultures, which further contributed to the diversification of caste identities. It is important to note that the status of women, untouchability, and slavery during this period varied across regions and cannot be generalized as having a singular trend.
