Ambala district is situated in the north-eastern corner of Haryana, bordering the state of Punjab to the west, Himachal Pradesh to the north, and the Union Territory of Chandigarh and the Haryana districts of Panchkula, Yamunanagar, and Kurukshetra. The terrain is largely alluvial plain, part of the Indo-Gangetic belt, with the Ghaggar and Tangri rivers being significant watercourses. The district lies at the foothills of the Shivalik range, giving its northern fringe a slightly undulating character.
Ambala district forms part of the Ambala administrative division of Haryana. The district is sub-divided into tehsils and sub-tehsils for revenue administration, and into community development blocks for rural development purposes. The principal sub-divisions include Ambala, Ambala Cantt, Naraingarh, and Barara. The district administration is headed by the Deputy Commissioner.
Ambala has long been a strategic location on the route between the Gangetic plains and the Punjab. The town gives its name to the district. During the period of British rule, Ambala became an important military station; the Ambala Cantonment was established in 1843 and remains one of the largest military cantonments in India. Ambala was also an early centre of the 1857 uprising in northern India.
After the partition of British India in 1947, Ambala became part of the East Punjab state. Following the linguistic reorganisation of Punjab in 1966, Ambala district became part of the newly formed state of Haryana. Subsequent administrative reorganisations have carved out parts of the older Ambala district to form Yamunanagar district (1989) and later Panchkula district (1995).
The economy of Ambala district combines agriculture, trade, defence-related services, and small-scale manufacturing. Ambala is widely known as a major Indian centre for the manufacture of scientific instruments and laboratory glassware, with a long-established cluster of producers supplying domestic and export markets. The district also has significant production of mixie and grinder components, sewing machines, and cloth markets. Wheat, rice, sugarcane and vegetables are the principal agricultural crops.
Ambala is a major rail junction on the Northern Railway, with Ambala Cantonment Junction (UMB) being one of the busiest railway stations in northern India. The city lies on National Highway 44 (the old NH-1), part of the Grand Trunk Road, and is connected by highways to Chandigarh, Delhi, Saharanpur and Hissar. Ambala Air Force Station is one of the oldest airbases of the Indian Air Force.
Ambala Cantonment hosts substantial Indian Army and Indian Air Force formations. The Ambala air base operates fighter aircraft squadrons of the Indian Air Force and gained renewed prominence as one of the bases for the Dassault Rafale fleet inducted by the IAF.
The population of the district is predominantly Hindi-speaking, with Punjabi also widely spoken owing to historical and geographical proximity to Punjab. Hinduism is the largest religion, followed by Sikhism, Islam and other faiths. The district has a relatively high level of urbanisation by Haryana standards because of the twin urban centres of Ambala City and Ambala Cantt.
The district hosts several educational institutions, including affiliated colleges of Kurukshetra University and private universities such as Maharishi Markandeshwar University in Mull
