Hazaribagh district is one of the twenty-four districts of Jharkhand state, India and the district headquarter located in Hazaribagh town. It is currently a part of the Red Corridor. Etymology The district is named after its headquarters, the town of Hazaribagh. The name, Hazaribagh consists of two Persian words, hazar meaning "one thousand", and bagh meaning "garden" - so, the literal meaning of Hazaribagh is 'a city of one thousand gardens'. According to Sir John Houlton, a veteran British administrator, the town takes its name from the small villages of Okni and Hazari – shown in old maps as Ocunhazry. The last syllable in its name probably originated in a mango-grove, which formed a camping ground for troops and travellers marching along the ‘new military road’ from Kolkata to Varanasi, constructed in 1782 and the following years.
