Nanda Empire: Magadha's Wealthy Dynasty Before the Mauryas

The Nanda Empire was the ruling dynasty of Magadha, in the eastern Ganges plain, from around 345 to 322 BC. Founded by Mahapadma Nanda and ending with Dhana Nanda, it built the largest and richest kingdom India had yet seen, with a capital at Pataliputra and a famously large army. Its overthrow by Chandragupta Maurya opened the way for the first empire to cover most of the subcontinent.

Origins and Mahapadma Nanda

By the 4th century BC, Magadha had defeated most of its neighbours under the Haryanka and Shishunaga dynasties. Around 345 BC, though the date is uncertain, Mahapadma Nanda seized the throne from the last Shishunaga king.

Indian and Greek sources agree that the Nandas were not of royal birth. The Puranas, Hindu texts of genealogy and legend, say Mahapadma was the son of the last Shishunaga king by a Shudra woman. The Greek historians Diodorus and Curtius report that the father of the Nanda king of their day was a barber who became the queen’s lover and murdered the old king.

The Puranas call Mahapadma “the destroyer of all Kshatriyas”, suggesting he crushed many older ruling clans. The Hathigumpha inscription of King Kharavela of Kalinga, from the 1st century BC, refers to a “Nandaraja” who had once taken an image from Kalinga, which suggests Nanda rule reached into Odisha.

Dhana Nanda and the empire

The sources give confusing accounts of the succession. The Puranas speak of nine Nandas, usually understood as Mahapadma and his eight sons, while Buddhist texts list nine brothers. The last king is generally known as Dhana Nanda, and Greek writers call him Agrammes or Xandrames.

The empire stretched from the Punjab borderlands across the Ganges plain to Bengal, with outlying conquests further south. The Greeks knew its peoples as the Prasii and the Gangaridai. Its capital, Pataliputra, stood at the junction of the Ganges and the Son rivers.

Army and wealth

The Nandas’ military power impressed foreign observers. According to Diodorus and Curtius, the king commanded 200,000 infantry, 20,000 cavalry, 2,000 chariots and 3,000 to 4,000 war elephants. Plutarch gives even higher figures of 80,000 cavalry and 6,000 elephants. These numbers were reported to Alexander’s army and cannot be checked.

Fear of this army may have contributed to the mutiny of Alexander’s troops at the Hyphasis River in 326 BC, after the hard-fought Battle of the Hydaspes. Ancient writers give several reasons, including exhaustion and homesickness.

The Nandas were also famous for wealth. Later Indian tradition remembered their treasure, and a Tamil Sangam poem refers to riches of the Nandas hidden in the Ganges. The Chinese pilgrim Xuanzang, in the 7th century AD, heard stories of Nanda treasures at Pataliputra. Silver punch-marked coins, stamped with several symbols, circulated widely in Magadha in this period, and some coin types are attributed to the Nandas.

Unpopularity and fall

Greek writers said the last Nanda king was hated by his subjects for his low birth and harsh rule, while Indian tradition remembered his greed and heavy taxes. These judgements come from hostile sources, written with hindsight.

Around 322 BC, the young Chandragupta Maurya overthrew the dynasty. Later stories credit the Brahmin Chanakya, also called Kautilya, who had been insulted at the Nanda court and vowed revenge. The Sanskrit play Mudrarakshasa, written centuries later by Vishakhadatta, dramatises the struggle against the last Nanda minister, Rakshasa. How the war was fought is not known. Buddhist and Jain stories say that Chandragupta first attacked the capital directly and failed, then conquered the frontier regions before closing in on Pataliputra. Jain tradition adds that Dhana Nanda was allowed to leave the city with as much as he could carry on one chariot.

Sources and uncertainties

Almost everything known about the Nandas comes from texts written long after their fall. The Greek accounts of Diodorus, Curtius and Plutarch go back to reports gathered by Alexander’s army in 326 BC, but were written down between the 1st century BC and the 2nd century AD. The Indian sources, the Puranas, Buddhist chronicles such as the Mahavamsa and its commentary, and Jain works such as Hemachandra’s 12th-century Parishishtaparvan, are later still.

These sources disagree on basic facts. The Puranas give the dynasty a total of 100 years and Mahapadma alone a reign of 88 years, which few historians accept, while Buddhist texts allow the nine Nandas only 22 years. Most modern scholars therefore place the dynasty within a few decades before about 322 BC.

Jain tradition remembers Nanda ministers from the family of Shakatala, whose son Sthulabhadra became an important Jain monk. No inscriptions of the Nanda kings themselves have been found, and no coins can be assigned to individual rulers with certainty.

Timeline

• c. 345 BC: Mahapadma Nanda overthrows the Shishunaga dynasty of Magadha.
• c. 345–322 BC: Nanda kings extend Magadha’s power across northern India and into Kalinga.
• 326 BC: Alexander’s army refuses to advance beyond the Hyphasis River.
• c. 322 BC: Chandragupta Maurya and Chanakya overthrow Dhana Nanda.

Why it matters

The Nandas turned Magadha into the dominant power of northern India, with a centralised treasury and a large standing army. The Maurya Empire inherited these foundations, and the story of the Nandas’ wealth, unpopularity and fall became a lasting lesson about power in Indian political tradition.
