After Battle of Buxar, Nagvanshi became vassal of East India Company. British reduced Nagvanshi rulers to Jamindar in 1817. In 1833, Captain Wilkinson established head quarter of the South-West Frontier agency in the village of Kishunpur, which he renamed into Ranchi after the hamlet of Purana Ranchi located at the foot of the Ranchi Hill. Thakur Vishwanath Shahdeo, Pandey Ganpat Rai, Tikait Umrao Singh and Sheikh Bhikhari played a pivotal role in the Indian Rebellion of 1857. British made Ranchi as municipality in 1869 and Ranchi was first termed as a town in the census of 1872. Freedom fighter Birsa Munda died in the Ranchi jail on 9 June 1900. In 1912, Jyotirindranath Tagore, the eldest brother of Rabindranath Tagore, settled in Ranchi. Tagore Hill, where his house was located, has been named after him in remembrance. The last ruler of the Nagvanshi dynasty was Lal Chintamani Sharan Nath Shahdeo (1931–2014).
