Explanation:

In Lohardaga district of South Bihar (now in Jharkhand), a major rebellion was led by Thakur Vishwanath Shahdeo who was part of the Nagavanshi dynasty. He was motivated by disputes he had with the Christian Kol tribals who had been grabbing his land and were implicitly supported by the British authorities. The rebels in South Bihar asked him to lead them and he readily accepted this offer. He organised a Mukti Vahini (people's army) with the assistance of nearby zamindars including Pandey Ganpat Rai and Nadir Ali Khan.
