city, central Haryana state, northwestern India. It is connected by rail with Delhi and by road with Bhiwani and Panipat. Rohtak, formerly called Rohtasgarh (Fort of Rohtas), is said to have been founded by Raja Rohtas, a Panwar Rajput. The Dini mosque there dates to 1140; excavations at the nearby Khokra Kot mound have revealed pieces of Buddhist sculpture. Rohtak is a major grain and cotton trade centre, and there is some light industry. Constituted a municipality in 1867, the city has an agricultural research station and is the seat of Maharshi Dayanand University (established 1976) and 12 affiliated colleges, including a medical school.
