The Nanda dynasty ruled in the northern part of the Indian subcontinent during the 4th century BCE, and possibly during the 5th century BCE. The Nandas overthrew the Shaishunaga dynasty in the Magadha region of eastern India, and expanded their empire to include a larger part of northern India. Ancient sources differ considerably regarding the names of the Nanda kings, and the duration of their rule, but based on the Buddhist tradition recorded in the Mahavamsa, they appear to have ruled during c. 345–322 BCE, although some theories date the start of their rule to 5th century BCE.
