The Pushyabhuti dynasty, also known as the Vardhana dynasty ruled in northern India during 6th and 7th centuries. The dynasty reached its zenith under its last ruler Harsha Vardhana (c. 590–647 CE), and the Empire of Harsha covered much of north and north-western India, extending till Kamarupa in the east and Narmada River in the south. The dynasty initially ruled from Sthanveshvara (in modern Kurukshetra district, Haryana), but Harsha eventually made Kanyakubja (modern Kannauj, Uttar Pradesh) his capital, from where he ruled until 647 CE.
