History of Sonipat District
Sonipat was earlier known as Sonprastha, which later on became Suvarnaprastha, meaning the `Golden City`. Over a period of time, the pronunciation of Suvarnaprastha got distorted into Swarnpat, and then to its current form, Sonipat. The earliest reference of this city comes in the epic Mahabharata, and at that time, it was one of the five villages demanded by the Pandavas in lieu of the kingdom of Hastinapur. It is believed that it was founded as Suvarnaprastha by the Pandavas, although it has been noted much earlier by Panini in his celebrated Ashtadhyayi. The town was therefore already in existence around 600 BC. Sonipat District has been carved out of Rohtak District and made a full fledged district on 22nd of December, 1972.
