The ruined Ghasera Fort lies at Ghasera village from Nuh city on Nun-Sohna highway. In 18th century, Ghasera was ruled by Bargurjar Rajputs whose territory included the parganas of Ghasera, Indor, Kotla, and Sohna. To their north was the Princely State of Nawabs of Farrukhnagar which was founded in 1732. To their west was the jagir of AhirRao's of Rewari with forts at Gokulgarh and Guraora. In the south were the ruler of Jats of Bharatpur State, and KachwahaRajput rulers of Alwar State. Mughal, who were protected by Marathas, had their territory shrunk to a nominal area from Delhi to Palam. In 1750 after Jat king Surajmal defeated Moghuls. he forced them to sign a treaty according to which Moghuls agreed to pay a large fee as war compensation and promised not to desecrate Hindu temples in Jat territory. In 1753, Surajmal killed "Rajput raja Bahadur Singh Bargujar" and his son "Ajit Singh" of "Koil" in the "Battle of Ghasera" and captured the Ghasera fort. During the "1753 Battle of Ghasera", the Jats laid siege to Ghasera, which lasted for 3 months. The Raos of Rewari, led by Bhawani Singh, who were traditional enemies of Bargurjar of Ghasera fought on the side of Jats. During the siege, 15000 jats and their allies were killed by the gun fire from ramparts of Ghasera fort. On 23 April 1753, a desperate Bahadur Singh Bargurjar slayed all his women, opened the gates of the fort for the final battle to death during which he and his companions were killed. After Ghasera, Jats once again turned to attack Delhi and they sacked Mughal capital in 1754, which resulted in Mughals pleading help from marathas. Marathas and Mughals laid siege of the Jat fort of Kumher. During the Maratha siege of Jats, the Mughal Imad-ul-Mulk assisted Bahadur Singh Bargujar's surviving son Fateh SinghBargujar to recover Ghasera from Jats in January 1754, but a contingent of Suraj Mal's son Jawahar Singh ousted Fateh Singh Bargujar from Ghasera. Maratha siege of Jats ended in peace treaty in 1754 between Jats and Maratha PeshwaMalharrao Holkar, facilitated by the Maratha ruler of Gwalior StateMahadaji Scindia with the help of Martaha Peshwa Malharrao Holkar's brother Raghunathrao.
