Ranchi is the capital of the Indian state of Jharkhand. Ranchi was the centre of the Jharkhand movement for a separate state for the tribal regions of South Bihar, northern Orissa, Western West Bengal and the present eastern Chhattisgarh. Jharkhand State was formed on 15 November 2000 by carving the Bihar divisions of Chota Nagpur and Santhal Parganas.
The name Ranchi comes from the original Oraon village Archi at the site. Archi derives from the Oraon word for bamboo grove or stave. According to legend, after an altercation with a spirit, a farmer beat the spirit with his bamboo stave or archi. The spirit shouted archi, archi, archi and vanished; Archi became Rachi, and Rachi became Ranchi. One historically significant neighborhood is Doranda , between the Hinoo (Bhusur) & Harmoo Rivers, where the civil station, treasury and church established by the British Raj were destroyed by rebel forces during the Sepoy Mutiny. The present Purani (old) Ranchi marks the site of the old village of Archi.
