The king of this State was Panchal Naresh whose daughter Draupadi was married to the Pandavas. The Historians identify Panchalya Desha as the area in Panchal range of mountains. Rajouri was also a part of this kingdom of Panchal Naresh. The region was then known as Rajapuri - 'the land of Kings'. It finds its mention in the travel account of Chinese traveller Hiuen Tsang who visited the town in 632 A.D. and described it as a part of Kashmiri territory. Still earlier in the Buddhist period, Rajouri formed a part of Gandhar territory (Afghanistan, Gandhar and Tashkent) and later was incorporated in the province called Darabhisanga which comprised the hilly stretch from Poonch to Kashmir. Those days Laharkote in Poonch district and Rajouri had emerged as two influential states of the area.
