Alwar State, a princely state established in 1770, was established by a Kachwaha Rajput named Pratap Singh who was earlier a jagirdar of "Dhai Gaon" (two-and-a-half villages) near Machari.
His successor "Bakhtawar Singh Kachwaha" was defeated after launching an armed incursion into neighbouring Jaipur State (ruled by their Kachwaha seniors, erstwhile overlords of his predecessor) and being forced to accept the consequent treaty mediated by East India Company prohibiting him from political relations with other states without the consent of the colonial British.
According to the "Gazetteer of Ulwar" published by the British raj, Alwar State was subdivided into four regions:
Rath region: current Behror and Neemrana, was ruled by Yadav and Lah Chauhan rajput zamindar who had descended from Prithviraj Chauhan.
Sahesh Mal was a son of Raja Sangat Singh Chauhan.
Sangat was the great grandson of Chahir Deo Chauhan, brother of famous king Prithviraj Chauhan.
In accordance with the pledge by the raja Sangat Singh Chauhan to his younger queen for marrying her in his old age, her two sons from him were bestowed the Rath area and its headquarter of Mandhan near Neemrana.
King Sangat Singh Chauhan's 19 sons from the older queen set out to seek their fortunes.
Of the 19 brothers, Harsh Dev Chauhan and Sahesh Mal Chauhan arrived in the Gurgaon district.
 Lah Chauhan, the ruler of Rath, was a son of raja Sangat Singh Chauhan by the younger Rani whose two sons became inheritors of Raja Sangat Singh's territory of Rath with its headquarter at Mandhan when other 19 sons from the other wives were required to quit the kingdom as per the promise of Raja Sangat.

Wai region: current Bansur and Thana Ghazi, was ruled by Shekhawat rajput zamindars.

Narukhand region: current Rajgarh and Laxmangarh, was ruled by Naruka sub-branch of Kachwaha rajputs who were from the same branch as the ruling kings of the Alwar State
Mewat region: current Palwal and Nuh districts, had the highest population of the Meo Muslims.
