Gopal Singh, a Tewatia Jat, the founder of the princely state of Ballabgarh, migrated from Alwalpur village in 1705, and established himself at Sihi ( from Ballabhgarh) after displacing Taga Brahman farmers there. Gopal Singh Tewatia of Sihi started establishing his power in Delhi, Khair and Mathura areas. He attacked Rajput of that area with the help of people of Lagon village. He became more powerful and richer and started to waylay the mughal travelers on Delhi–Agra royal route during the reign of Aurangzeb (d. 1707).
