History of Mahendragarh District
Although the nomenclature of Mahendragarh District is not very old, the antiquity of the area it covered can be stretched to earlier periods also. The Archaeological explorations conducted in the region have brought to light late Harappan sites especially from its Rewari tehsil. Most of the sites explored in the district belong to the late-medieval period. However, it has been suggested that some of the present streams of the district may be identified with those mentioned in early Vedic literature. The succeeding stages in the historical growth of the district cannot be traced in because of the absence of concrete evidences. Possibly it was included in the empire of the Mauryas, the Guptas, and the Gurjara- Pratiharas. After the death of Muhammad Ghori, one of his generals, Qutub-ud-din Aibak, laid the foundations of the Turkish rule in India in 1206.

Further, after Firoz Shah`s death, Mahendragarh along with other adjacent territories went out of the control of the Tughlaqs. The Sayyids after Tughlaqs, tried to bring the district under their control, but they also seem to have achieved little success. Soon after establishing his rule in northern India, Babur brought the district under his effective control. Humayun, who succeeded Babur in 1530, made no change in the existing administrative arrangement. Sher Shah was an administrative genius. He divided his whole kingdom into sixty six sarkars. Mahendragarh came under the sarkars of Narnaul and Rewari. Sher Shah ruled for only five years (1540-45). After the death of Aurangzeb, the district`s position changed drastically. In 1750 Raja Madho Singh of Jaipur seized a sizeable territory in the district around Narnaul and Kanaud. In 1792, the Maratha chief Mahadji Sindhia succeeded in capturing the district. The British rulers too reached Rewari. With the launch of Non Cooperation Movement by Mahatma Gandhi, the struggle became still more intense. In 1930, the Civil Disobedience Movement was launched by Mahatma Gandhi. The district contributed heavily in the country`s freedom struggle.

After India achieved independence, Mahendragarh district along with the other districts of Patiala State formed part of the Patiala and East Punjab State Union (PEPSU) in 1948, which merged with Punjab in 1956. Haryana was carved out of Punjab in 1966 and Mahendragarh became the district of the new state.
