Ancient texts also suggest that the Nandas were unpopular among their subjects because of their low-status birth, excessive taxation, and general misconduct.
Modern historians generally identify the ruler of the Gangaridai and the Prasii mentioned in ancient Greco-Roman accounts as a Nanda king.
[8] According to Greek historian Diodorus (1st century BCE), Porus told Alexander that the contemporary Nanda king was thought to be the son of a barber.
[9][10] The Jain tradition, as recorded in the Avashyaka Sutra and the 12th-century text Parishishta-parvan, corroborates the Greco-Roman accounts, stating that the first Nanda king was the son of a barber.
However, even these texts hint at the low birth of the Nandas, when they state that Mahapadma's mother belonged to the Shudra class, the lowest of the varnas.
Proponents of this theory also interpret the Hathigumpha inscription to mean that "Nandaraja" (the Nanda king) flourished in year 103 of the Mahavira Era, that is, in 424 BCE.
According to historian R. C. Majumdar, while all the chronological details provided by Merutunga cannot be accepted without corroborative evidence, they cannot be dismissed as entirely unreliable unless contradicted by more reliable sources.
[1][10] The Puranas, compiled in India in c. 4th century CE (but based on earlier sources), also state that the Nandas ruled for two generations.
[21] According to the Sri Lankan Buddhist text Mahavamsa, written in Pali language, there were 9 Nanda kings – they were brothers who ruled in succession, for a total of 22 years.
The Greek accounts state that Agrammes (identified as a Nanda king) was the ruler of the Gangaridai (the Ganges valley) and the Prasii (probably a transcription of the Sanskrit word prachyas, literally "easterners").
[3] An analysis of various historical sources – including the ancient Greek accounts, the Puranas, and the Hathigumpha inscription – suggests that the Nandas controlled eastern India, the Ganges valley, and at least a part of Kalinga.
[26] The Kshatriyas said to have been exterminated by him include Maithalas, Kasheyas, Ikshvakus, Panchalas, Shurasenas, Kurus, Haihayas, Vitihotras, Kalingas, and Ashmakas.
[33] Some Kuntala country (North Mysore) inscriptions suggest that the Nandas also ruled it, which included a part of present-day Karnataka in southern India.
The Magadha empire included parts of southern India during the reign of the Mauryas – the successors of the Nandas – but there is no satisfactory account of how they came to control this area.
[31] For example, an inscription discovered at Bandanikke states: the Kuntala country (which included the north-western parts of Mysore and the southern parts of the Bombay Presidency) was ruled by the nava-Nanda, Gupta-kula, Mauryya kings; then the Rattas ruled it : after whom were the Chalukyas; then the Kalachuryya family; and after them the (Hoysala) Ballalas.Alexander the Great invaded north-western India at the time of Agrammes or Xandrames,[1] whom modern historians generally identify as the last Nanda king – Dhana Nanda.
[34] In the summer of 326 BCE, Alexander's army reached the Beas River (Greek: Hyphasis), beyond which the Nanda territory was located.
Alexander's soldiers had first started to agitate to return to their homeland at Hecatompylos in 330 BCE, and the stiff resistance that they had met in north-western India in the subsequent years had demoralised them.
[39] Greek authors also refer to the Gangaridae and Prasioi as having a fine military tradition, suggesting the fact that during Alexander the Great's invasion of India in the late 4th century BCE, the country was under the rule of two factions.
Historian H. C. Raychaudhuri theorises that the Nandas held centralised control over their core territories in present-day Bihar and Uttar Pradesh, but allowed considerable autonomy in the frontier parts of their empire.
[40] This is suggested by Buddhist legends, which state Chandragupta was unable to defeat the Nandas when he attacked their capital but was successful against them when he gradually conquered the frontier regions of their empire.
[42] The Nanda kings appear to have strengthened the Magadha kingdom ruled by their Haryanka and Shaishunaga predecessors, creating the first great empire of northern India in the process.
Some historians have suggested that Magadha was relatively free from the Brahmanical orthodoxy, which may have played a role in its political success; however, it is difficult to assess the veracity of this claim.
Singh, however, notes that the adjoining Chota Nagpur Plateau was rich in many minerals and other raw materials, and access to these would have been an asset for Magadha.
[45] Greek writer Xenophon, in his Cyropaedia (4th century BCE), mentions that the king of India was very wealthy, and aspired to arbitrate in the disputes between the kingdoms of West Asia.
[49] Greater Magadha, east of the confluence of the Ganges and the Yamuna, was the area where the second urbanisation took place, and where Jainism and Buddhism originated.
[55] In response, Brahmins broadened their services,[56] eventually resulting in the Hindu synthesis of Brahmanical orthodoxy with local religious traditions,[57][58][59] which came to dominate India.
When Shakatala, a minister of the last Nanda king, died, his son Sthulabhadra refused to inherit his father's office, and instead became a Jain monk.
According to Diodorus, Porus told Alexander that the contemporary Nanda king was a man of "worthless character", and was not respected by his subjects as he was thought to be of low origin.
