Birsa Munda’s movement transformed Adivasi resistance from a local revolt into a wider assertion of identity, land rights and self-governance. Discuss. ⚜️First, it asserted land rights.

Birsa was revered as Dharti Aba, and his vision located identity in ancestry, community, land and culture rather than religion alone. ⚜️Third, it articulated self-rule through the idea of disum, reflecting community autonomy and resistance to external domination. ⚜️Fourth, it shaped later politics. Dombari Buru became a symbol of resistance, and Birsa’s legacy influenced the Jharkhand statehood movement. ⚠️VK IAS subject wise channels - Click here
