Ambala district has an extremely interesting past. The district was explored during British period by A.C.Cunningham and C.Rodgers and later by shri B.B.Lal and others. On the basis of various literary and archeological evidences it is possible to give an outline of culture and history of Ambala district. The earliest literary reference to the region comprising the Ambala district is found in the Hindu scripture Taittiriya Aranayaka which mentions Turghna as the bordering region towards the North of Kurukshetra. This locality identified with Shrughna Sugh also finds mention in Panini (Ancient Indian literature). It is surmised that Ambala district was founded by Amba Rajput during the 14th century AD. Another version is that the name is a corruption of Amba Wala or the mango-producing village, judging from mango groves that existed in its immediate neighbourhood or maybe the district has been named after goddess "Bhawani Amba" whose temple still exists in Ambala city.
Ambala is known as a town of scientific instruments. It is divided into two parts: Ambala Cantt (cantonment) and Ambala City, about 3 kilometers apart from each other. Within the cantonment area, Ambala has a large presence of Indian Army and Indian Air Force. The cantonment was established in the year 1843, after the British abandoned its cantonment at Karnal. The cantonment houses the '2 corps', one of the three strike corps of Indian Army and is of immense strategic importance.
