How did asoka unify the maurya empire

Asoka unified the empire by conquering unexplored tribal and forested regions. Asoka also converted from Hinduism to Buddhism and helped make Buddhist temples all over the region. He had a violent conquest over Kalinga (which was a state separate from his empire) and reunited all of these separate states until he was ruling a vast majority of what is now the Indian Subcontinent (India, Pakistan and Bangladesh). He accomplished more than his ancestors had ever accomplished.
