Jats

Jats were a prosperous agriculturist caste inhabiting the Delhi-Agra belt who consolidated their power during the 17th and 18th centuries.
Towns like Panipat and Ballabhgarh emerged as important trading centres in their territory. When Nadir Shah invaded Delhi in 1739, many citizens from Delhi took refuge in these towns.
Churaman and Badan Singh founded the independent Jat state at Bharatpur. Suraj Mal consolidated Jat power during his rule from 1756 to 1763. The death of Suraj Mal died in 1763 marked the demise of the Jat state.
Geographical expanse: Ganga in the East, Chambal in the South, Delhi in the North and Agra in the West.
Suraj Mal possessed great administrative ability, especially in the fields of revenue and civil affairs.
