Chandragupta Maurya (Sanskrit: चन्द्रगुप्त मौर्य महान Hindi: चन्द्रगुप्त मौर्य महान), (born c. 340 BCE, ruled c. 320 BCE, – 298 BCE) was the founder of the Maurya Empire. He succeeded in conquering most of the Indian subcontinent and is considered the first unifier of India as well as its first genuine emperor. In foreign Greek and Latin accounts, Chandragupta is known as Sandrokyptos (Σανδρόκυπτος), Sandrokottos (Σανδρόκοττος) or Androcottus.

Prior to Chandragupta's consolidation of power, small regional kingdoms dominated the northwestern subcontinent, while the Nanda Dynasty dominated the middle and lower basin of the Ganges. After Chandragupta's conquests, the Maurya Empire extended from Bengal and Assam in the east, to Afghanistan and Balochistan,some part of the easten and south-east Iran in the west, to Kashmir and Nepal in the north, and to the Deccan Plateau in the south. Tradition holds that Chandragupta abdicated his throne to become a monk and led such an ascetic life that he starved himself to death. Whether or not this is factually accurate, he was succeeded by his son in 298 BC.
