Origin of the Name
The district is named after Jalandhar, a demon king, who finds a mention in the Puranas and Mahabharta. According to another legend, Jalandhar was the capital of the kingdom of lav, son of Rama. According to yet another version Jalandhar is said to have derived its name from the vernacular term Jalandhar means area inside the water, i.e. tract laying between the two rivers Satluj and Beas, still another name of Jalandhar had been Trigartta, as it was waters by three rivers, Satluj, Beas and Ravi
In ancient time, the district or Kingdom of Jalandhar comprised the whole of the Upper Doabas from the Ravi to the Satluj. According to the Padama Purana, as quoted by General Conningham the country takes its name from the great Daitya King Danava Jalandhara the son of the Ganga by Ocean.
The whole of Punjab and the area of present Jalandhar District was part of the Indus Valley Civilization. Harappa and Mohenjodaro are the sites where remains of the Indus Valley Civilization have been found extensively. The archaeological exploration made during the recent years have pushed the antiquity of the Jalandhar District of the Harappa period.
