The Maukhari dynasty was a post-Gupta dynasty who controlled the vast plains of Ganga-Yamuna for over six generations from their capital at Kanyakubja. They earlier served as vassals of the Guptas and later of Harsha's Vardhana dynasty. The Maukharis established their independence during the mid 6th century. The dynasty ruled over much of Uttar Pradesh and Magadha. Around 606 CE, a large area of their empire was reconquered by the Later Guptas. According to Hieun-Tsang, the territory may have been lost to King Shashanka of the Gauda Kingdom, who declared independence circa 600CE.
