Explanation:

The year 1833 was important landmark in Haryana's history. In this year, the Bengal Presidency under the East India Company was divided into two provinces of Bengal and North Western Province. Most areas of Haryana and Delhi together became one of the six divisions of north western Province, called the Delhi division.

The Delhi division was further sub-divided into seven princely states and five districts. The princely states were Bahadurgarh, Ballabhgarh, Dujana, Farukhnagar, Jhajjar, Loharu and Pataudi. The five districts were Delhi, Gurgaon, Rohtak, Panipat and Hissar. These districts were divided into Tehsils and Tehsils were bifurcated into Zails.

The officer heading the Delhi division was called a Commissioner instead of the Resident. At this time, some areas of the present-day Haryana were outside the Delhi division and were considered to be a part of the "upper region". These were the districts of Ambala and Thanesar and the princely states of Buria, Chhachhrauli and Jind. But the people of "upper region" and Delhi division, though administratively in different provinces, were closely bound by socio-cultural ties. This administrative system continued till the Revolt of 1857.
