Answer: Kolhan region
Notes: Recently, Ho tribe adivasis staged a protest in West Singhbhum district, Jharkhand against administration interference in their Manki-Munda system. The Ho or Kolha people are an Austroasiatic Munda ethnic group of India. They call themselves Ho, Hodoko, and Horo, meaning human in their language. They are mainly found in the Kolhan region of Jharkhand, Odisha, West Bengal, and Bihar. In the Manki-Munda system, the Munda (village head) resolves socio-political disputes at the village level. Each village had one hereditary Munda. A Manki headed a pidh of 8–15 villages and handled unresolved cases. Manki and Munda had no role in land or revenue matters. It was a purely internal self-governing system, with no taxation or external sovereign control.
