Chatra is one of the twenty-four districts of Jharkhand state, India, and Chatra is the administrative headquarters of this district. The district covers an area of 3706 km². It has a population of 790,680 (Census 2001).
In ancient period, the area covered by the present district and adjoining areas were ruled by a number of states, which were collectively known as the Atavika (forest) states. These states accepted the suzerainty of the Maurya empire during Ashoka’s reign (c.232 BCE). Samudragupta, while marching through the present-day Chotanagpur region, directed the first attack against the kingdom of Dakshina Kosala in the Mahanadi valley
During Muhammad bin Tughluq’s reign, the territory which comprises the present district came in contact with the Delhi sultanate. Later, it became a part of the Bihar Subah of the Mughal empire. Daud Khan, the Mughal Subahdar of Bihar, during the reign of Aurangzeb occupied Kothi near Pokhri Fort on 5 May 1660, without much opposition, and then he moved towards the fort of Kunda which had a very strong fortification as it was situated on a hilltop. This fort was finally occupied by him and was completely destroyed on the 2 June 1660. Later, Kunda Fort was under the possession of the Raja of Ramgarh. In 1734, Aliwardi Khan advanced towards Kunda after defeating the rebel Zamindars of Tikari (Gaya). He mounted an attack on Chatra Fort and demolished it
The British East India Company came in contact with this region for the first time in 1769. Raja Rammohan Roy, worked as a serestadar at Chatra from 1805–06 and stayed both at Chatra and Ramgarh while in office.
