Devapala was a great ruler who ruled the Pala Empire of Bengal in the Indian Subcontinent from 810 to 850 CE. He succeeded his father, Dharamapala (ruled 770–810 CE), as the third king of the dynasty. He inherited a vast empire that his father had constructed and contributed significantly to its expansion. He expanded the empire's borders by capturing modern-day Assam and Orissa. His vast realm was marked on the west by Kambhoja, the south by the Vindhya mountain range, the north by the Himalayas, and the east by the Bay of Bengal.
