He was a member of the Vardhana dynasty; and was the son of Prabhakarvardhana who defeated the Alchon Huna invaders, and the younger brother of Rajyavardhana, a king of Thanesar, present - day Haryana . At the height of Harsha's power, his Empire covered much of North and Northwestern India, extended East till Kamarupa, and South until Narmada River; and eventually made Kannauj (in present Uttar Pradesh state) his capital, and ruled till 647 CE . Harsha was defeated by the south Indian Emperor Pulakeshin II of the Chalukya dynasty, when Harsha tried to expand his Empire into the southern peninsula of India . </P> <P> The peace and prosperity that prevailed made his court a centre of cosmopolitanism, attracting scholars, artists and religious visitors from far and wide . The Chinese traveller Xuanzang visited the court of Harsha and wrote a very favourable account of him, praising his justice and generosity . His biography Harshacharita ("Deeds of Harsha") written by Sanskrit poet Banabhatta, describes his association with Thanesar, besides mentioning the defence wall, a moat and the palace with a two - storied Dhavalagriha (white mansion). </P> <P> After the downfall of the Gupta Empire in the middle of the 6th century, North India was split into several independent kingdoms . The northern and western regions of India passed into the hands of a dozen or more feudatory states . Prabhakara Vardhana, the ruler of Sthanvisvara, who belonged to the Vardhana family, extended his control over neighbouring states . Prabhakar Vardhana was the first king of the Vardhana dynasty with his capital at Thaneswar . After Prabhakar Vardhana's death in 605, his eldest son, Rajya Vardhana, ascended the throne . Harsha Vardhana was Rajya Vardhana's younger brother . This period of kings from the same line has been referred to as the Vardhana dynasty in many publications . </P>
