Harsha

Harsha or Harsha Vardhana (c. 590—647)
. He was the son of Prabhakara Vardhana and younger brother of Rajya Vardhana, a king of Thanesar, Haryana.. Harsha himself was a Mahayana Buddhist. Harsha was a tolerant ruler and supported all Indic (or Hindu) faiths – Buddhism, Vedism and Jainism. His sister Rajyashri's conversion to Buddhism presumably had a positive effect on his support to the religion. His approach to religion is evident in his celebrated play Nagananda. The play's theme is based on the Jataka tale of the Bodhisattva Jimutavahana, but Harsha introduces the Goddess Gauri, Shiva's consort, as the saviour of Jimutavahana, a feature not found in the Jataka. The great Indian mathematician Brahmagupta also lived in the Empire of Harshavardhana. In 643 he held a Buddhist convocation at Kannauj . He wrote three Sanskrit plays – Nagananda, Ratnavali and Priyadarsika.  his court poet Bana and Xuanzang. Bana composed an account of Harsha's rise to power in Harsha Charitha, the first historical poetic work in Sanskrit language. Xuanzang wrote a full description of his travels in India. He is credited with two significant poems on Buddhist themes - the Ashtamahasricaityastotra (Praise to Eight Grand Caityas [Buddhist assembly halls]) and Suprabhatastotra (Laud to Morning) - and a tract on grammatical gender, the Linganusasanam. After Harsha's death, apparently without any heirs, his empire died with him. The kingdom disintegrated rapidly into small states.
