Rohtak is the 40th largest Hindi speaking city of India with a total population of 3,70,000. Another major language of Rohtak is Haryanvi. Highest employment in the Rohtak district is in Agriculture, with the Government and in the Hardware and Chemical Industries, with 52% of the workers in Industry and Services, 45% Agricultural workers and 3% Household workers. Rohtak is a good agricultural belt because of the presence of relatively high levels of underground water and despite the absence of perennial rivers in the district. The main crops cultivated are wheat, gram, sugarcane and bajra. Rohtak is amongst the oldest organized districts of Haryana. Archaeological excavations indicate the continuity of settlements in the Rohtak district to be as old as the Indus valley Civilization. Rohtak is identified with Rohitika, a place mentioned in the Mahabharata and was quite possibly the capital of Bahudhanyaka, the kingdom of Yaudheyas. In the Vinaya of the Mulasarvasti-vadins, Jivaka is represented as taking a journey from Taxila in the north west of Bhadramkara, Udumbasa, Rohitaka and Mathura in the Ganga Doab. The existence of the town during the rule of Kushan is testified by the recovery of a Khushana Pillar Capital decorated with carvings of winged lions and riders. The riders are similar to the elephant riders at Karli cave and figures at the Gateway of the Stupa of Sanchi. Rohtak played an important role during the Mughal period and the British officers began residing here since 1810. All Saints Church was built by the British in 1867.
