Harsha Vardhan : After the decline of Gupta empire, Vardhana Dynasty held its sway in northern India. Of all the kings of the dynasty Harsha Vardhana (606-647), the son of King Prabhakar Vardhan who ascended the throne of Thaneshwar in 606 A.D. was most important.
He subdued the whole region from. Assam to Kathiawad but in the south his efforts to extend his empire beyond Narmada river was defeated by King Pulakesin II (609-642) of Chalukya dynasty.
Harsha Patronized Brahmans, Buddhists and Jains alike. Himself a poet, Harsha encouraged literature. Bana, the great Sanskrit author was his contemporary and his-‘Kadambari’ contains elaborate account of Harsha’s life
Hiuen Tsang : He was a Chinese pilgrim who stayed in India during Harsha’s time and studied at Nalanda, the international Buddhist University which flourished at the time.
Harsha having died heirless, his empire disintegrated. It caused the emergence of petty warring Rajput states. Of them, Prithviraj Chauhan (1172-1191) the ruler of Delhi was important. His defeat at the hands of Mohammad Ghori brought to an end the saga of Hindu rule and ushered in an era of Muslim rule.
This is all about Vardhana Dynasty.
