 Budhagupta had close ties with the rulers of Kannauj and together they sought to run the Alchon Huns (Hunas) out of the fertile plains of Northern India.Northern India, and in particular the area of Eran was next invaded by the Alchon Huns ruler Toramana who set up his own inscription there, the Eran boar inscription of Toramana, circa 510-513 CE.The Damodarpur copper-plate inscription informs us that Pundravardhana bhukti (the present-day North Bengal) was ruled by his two viceroys ("Uparika Mahararaja") Brahmadatta and Jayadatta.
