About 600 A.D. India was exhausted by her struggle with the Huns. After it there remained only a multitude of small states and obscure dynasties, but there was evidently a readiness to accept any form of unifying and tranquillizing rule and for nearly half a century this was provided by Harsha. He conquered northern India from the Panjab to Bengal but failed to subdue the Deccan. Though a great part of his reign was spent in war, learning and education flourished. Hsüan Chuang, who was his honoured guest, gives a good account of his administration but also makes it plain that brigandage prevailed and that travelling was dangerous. After 643 Harsha, who was growing elderly, devoted much attention to religion and may be said to have become a Buddhist, while allowing himself a certain eclectic freedom. Several creeds were represented among his immediate relatives. Devotion to Śiva was traditional in the family: his father had been a zealous worshipper of the Sun and his brother and sister were Buddhists of the Sammitîya sect. Harsha by no means disowned Brahmanic worship, but in his latter years his proclivity to Buddhism became more marked and he endeavoured to emulate the piety of Asoka. He founded rest houses and hospitals, as well as monasteries and thousands of stupas. He prohibited the taking of life and the use of animal food, and of the three periods into which his day was divided two were devoted to religion and one to business. He also exercised a surveillance over the whole Buddhist order and advanced meritorious members.
