[3] Under him, Bharatpur State, a tributary of the House of Scindia,[4] covered the present-day districts of Agra, Alwar, Aligarh, Bharatpur, Dholpur, Etawa, Hathras, Mainpuri, Meerut, Ghaziabad, Mathura, and Rohtak, Sonipat, Jhajjar, Nuh, Palwal, Faridabad, Kasganj, Mainpuri, Firozabad, Bulandshahr.

[5][6][7][8][9] A contemporary historian had described him as "the Plato of the Sinsinwar tribe" and by a modern writer as similar to the "Ulysses", because of his "political sagacity, steady intellect and clear vision.

Maharaja Surajmal was born on 13 February 1707, to Raja Shri Badan Singh and Rani Devki in a Hindu Jat family of Sinsinwar clan of in Bharatpur Kingdom (present-day Rajasthan, India).

Fateh Ali Khan sought Suraj Mal's help, and in November 1745, he took his first independent decision in external political and army affairs.

The war at Chandaus resulted in the death of Asad Khan and the defeat of the royal army, thereby increasing the power of Bharatpur Kingdom.

On 14 May the supporters of Suraj Mal sacked Chārbāg, Bāg-e-kultāt and Hakīm Munīm Bridge; the next day, Jaisinghpura went on to burn several areas.

On 16 May Suraj Mal under Safdar Jang attacked Delhi and defeated Sādil Khan and Raja Devidatta in battle.

While inspecting the troops on an open palanquin in the battle of Kumher, Khanderao was hit and killed by a cannonball from the Bharatpur army.

[25][26] After successfully defending Kumher against 80,000 men led by Malhar Holkar, Imad, and a Jaipur General, his fame spread all over India.

[27] After his victory over Dattaji on 10 January 1760, Durrani came to Delhi, and called upon Suraj Mal to pay him tribute and join his camp.

Later, he realized that it would require a long time to reduce the strongly fortified, largely garrisoned and heavily provisioned fortress.

The fort could have resisted for long; but the qiladar was disheartened at the occupation of the entire upper Ganga Doab by the Afghans, and to save himself from a massacre, he capitulated in a fortnight or so.

[28] Madho Singh of Jaipur had occupied Alwar Fort by paying Rupees 50 thousand as bribe to its custodian and sending 500 men.

On 3 May 1761 the army of Suraj Mal with 4,000 soldiers reached Agra under the command of Balram and gave the message of Suraj Mal to the kiledar (in charge) of Agra Fort that the army wanted to cross the Yamuna and required a place to camp, which the kiledar gave his sanction.

[30] The Battle of Panipat in 1761 marked a significant turning point in the history of Northern India, as it disrupted the Marathas' ambitions and brought no permanent peace to Islam.

Maharaj Surajmal aimed to seize this opportunity to establish a Jat confederacy between the Abdāli and the Rohillas, expel Najib-ud-Daula from Delhi, restore his protégé Ghazi-ud-din, and control the empire's policy.
