Pre-historic and Ancient Period
The earliest reference to Haryana occurs in a Chahamana Inscription describing Arnoraja as carrying arms into Haritanaka (i.e. Haryana 1). The territorial designation Hariala mentioned in the Skandapurana2 also stands for the same region. The Delhi Museum Inscription of the reign of Muhammad Tughluq (A.D. 1328) gives the name as Hariyana `the very heaven on earth and where lies the city Dhillika (Delhi), built by the Tomaras3. This agrees with the Palam Baoli Inscription of the time of Balban (A.D. 1280) which provides its variant name Hariyanaka4.
