The conquest of the Nanda Empire under Dhana Nanda by a force under Chandragupta Maurya in the 4th century BC led to the establishment of the Maurya Empire. Little is known for certain of the conflict.


The story of the main figures involved and the conquest is obscure.[1] The Nanda Empire, led by Dhana Nanda, was based in Magadha and containing many of the kingdoms in the Ganges basin.

Chandragupta was said to have been a Kshatriya of noble background with military experience. According to Plutarch, he met Alexander the Great[2][3] and borrowed from Greek and Buddhism methods of statecraft and war fighting.[4] Chanakya, his chief advisor, was the son of a Brahmana of Taxila.[1]


Much of what is known about the conquest comes from accounts written long after the war itself. Ancient historian, Plutarch (AD 46 – AD 120) gives an account of parts of the conquest.[3] The conquest was fictionalized in Mudrarakshasa, a political drama in Sanskrit by Vishakadatta composed between 300 CE and 700 CE.[5] The history is also briefly recounted in Vishnu Purana (unknown date), which emphasizes the importance of Chanakya in the destruction of the Nanda empire.[6] In another work, Milinda Panha (dating from 100 BCE), Bhaddasala is named as a Nanda general during the conquest.[5]

Estimates of the number of soldiers involved are based in part on ancient Roman sources. Plutarch estimates that Candragupta's army would later number 600,000 by the time it had subdued all of India,[1] an estimate also given by Pliny ((23 AD–79 AD)). Pliny and Plutarch also estimated the Nanda Army strength in the east as 200,000 infantry, 80,000 cavalry, 8,000 chariots, and 6,000 war elephants. These estimates were based in part of the earlier work of the Seleucid ambassador to the Maurya, Megasthenes.[7] One 21st-century author, Suhas Chatterjee, suggests that "Chandragupta had to engage all his military strength, even Greek mercenaries from Punjab in his conquest of the Nanda king" and according to references about the conquest in the Milinda Panha "One Crore of soldiers, 10,000 elephants, 100,000 horses and 5,000 charioteers were killed in the encounter".[8]

In Mudrarakshasa, Chandragupta was said to have first acquired Punjab, and then combined forces with Chanakya and advanced upon the Nanda Empire.[5] Similarly, Plutarch writes that he first overthrew Alexanders Prefects in the northwest of India.[3] P. K. Bhattacharyya concludes that the war would have consisted of gradual conquest of provinces after the initial consolidation of Magadha.[1] In Mudrarakshasa, he laid siege to Kusumapura (or Pataliputra now Patna), the capital of Magadha, with the help of north-west frontier tribe mercenaries from areas already conquered.[5] The siege may have begun in 320 BCE.[9] By 312 BCE he had conquered all of north and north-west India.[5]

In the war, Chandragupta may have allied with the King of Simhapura in Rajputana and Gajapati[disambiguation needed] King of Kalinga (modern day Orissa).[10] The prior experience of his mercenaries from the Punjab were likely important in his military success.[2] It is also suggested that Chandragupta's campaign was laid out by using popular guerrilla tactics, as the Nanda Empire was large and had been able to wield large armies that would have been overwhelming to oppose by an upstart.[9] The war brought an end to the Nanda Dynasty and established the Maurya Empire with Chandragupta Maurya as its leader.


Maurya consisted of at least four provinces at the end of Candragupta's conquests: Avantirastra (capital: Ujjayini), Daksinapatha (capital: uncertain, perhaps Suvarnagiri), Uttarapatha (capital: Taksasila), and Pracya (capital: Pataliputra).[1] Chanakya later became Chandragupta's prime minister.[2]

Chandragupta eventually expanded his empire to southern India and warred with the Seleucid Empire over control over all of north western India and parts of Persia. The Maurya Empire eventually became the most extensive empire in India seen up to the date of when he abdicated.[9]
