The Maurya Empire stands as one of the most remarkable political achievements in human history. Built on the ambitions of Chandragupta Maurya, sharpened by Kautilya’s brilliant statecraft, and expanded under Ashoka’s moral authority, this vast empire stretched across virtually the entire Indian subcontinent. Yet within fifty years of Ashoka’s death, this colossal structure had completely unraveled. What went wrong — and who was responsible?
To answer that, we need to look closely at the rulers who came after Ashoka, the forces tearing the empire apart from within, and the historical debates surrounding this dramatic collapse.
Ashoka’s Successors: A Dynasty in Disarray
Ashoka left behind several sons, but the ancient sources are frustratingly inconsistent about who actually ruled after him. His inscriptions mention only one son by name — Tivara — and his mother, Karuvaki. Tivara, however, appears never to have sat on the throne of Magadha. Buddhist literature identifies Mahendra as another son, famously sent to Sri Lanka to spread Buddhism. His deep religious commitment likely kept him away from imperial politics entirely.
The Puranas — ancient Hindu compilations — offer conflicting succession lists. The Vayu Purana names Kunala, Bandhupalaita, Indrapalaita, Devavarman, Shatadhanush, and Brihadratha. The Vishnu Purana lists Suyashas, Dasharatha, Sangata, Shalishuka, Somasharman, and Brihadratha. The Matsya Purana offers yet another sequence, while the Bhagavata Purana and the Divyavadana each present their own variations. The Tibetan historian Taranatha adds Kunala, Vigatasoka, and Virasena to the mix.
This confusion itself tells a story: the later Maurya period was so politically fragmented that even contemporary and near-contemporary sources couldn’t agree on who ruled when.
Kunala and the Beginning of Decline
According to most Puranic accounts, Kunala succeeded Ashoka. Scholars like H.C. Raychaudhuri believe that “Suyashas,” mentioned in the Vishnu and Bhagavata Puranas, was actually Kunala’s title rather than a separate ruler. The Divyavadana calls him “Dharmavivardhana.”
Kunala was blind, which made direct rule practically impossible. Both Jain and Buddhist texts agree that real power passed to his son, Samprati. This early transfer of authority set a troubling precedent — the emperor’s personal limitations were already determining the fate of millions.
Meanwhile, Ashoka’s other sons were carving out independent kingdoms. According to the Rajatarangini, Jalauka established an independent state in Kashmir. Taranatha records that Virasena, another son, ruled Gandhara autonomously. The empire was fragmenting even before Kunala’s reign had properly begun.
Dasharatha and Samprati: A Divided Empire
Inscriptions at the Nagarjuni Hills caves, combined with Puranic accounts, confirm that Dasharatha was Kunala’s son. He adopted the title “Devanampiya” (Beloved of the Gods) — the same title Ashoka had used — and donated the Nagarjuni caves to the Ajivika religious sect. The Matsya and Vayu Puranas also identify him as Ashoka’s grandson.
The evidence strongly suggests that after Kunala, the empire split in two. Dasharatha controlled the eastern territories, including Magadha itself, while Samprati administered the western regions. The Puranas credit Dasharatha with a reign of eight years.
Samprati outlived Dasharatha and apparently recaptured Pataliputra, reunifying at least part of the empire. In Jain tradition, Samprati occupies the same revered position that Ashoka holds in Buddhist literature. Jain texts call him “Trikhandadhipati” — lord of three continents — and portray his reign as the zenith of Maurya power. The Puranas give him a nine-year reign.
The Later Rulers: Decline Accelerates
After Samprati, the throne passed through a series of increasingly obscure and ineffective rulers. The Vishnu Purana and the Garga Samhita identify Shalishuka as the next significant Maurya king. The Garga Samhita describes him in stark terms: quarrelsome, cunning, irreligious, and brutal toward his subjects. Where Ashoka had preached compassion, Shalishuka apparently practiced oppression.
Devavarman and Somasharman may have been the same person. Similarly, Shatadhanush and Shatadhanva appear to be variant names for a single ruler. Vrishasena and Punyadharman remain largely unknown figures.
The final Maurya emperor, Brihadratha, appears not only in the Puranas but also in the Harshacharita, the seventh-century biography of Emperor Harsha. According to that account, Brihadratha was murdered in front of his own army by his commander-in-chief, Pushyamitra Shunga, who then seized the throne — ending the Maurya dynasty around 185 BCE and founding the Shunga dynasty in its place.
Why Did the Maurya Empire Fall? A Closer Look at the Causes
The collapse of the Maurya Empire has fascinated historians for generations. This was not simply a matter of military defeat or natural disaster. It was a slow implosion — and its causes were multiple, interlocking, and deeply rooted.
1. Weak and Incompetent Successors
The most immediate cause of the empire’s collapse was the quality of rulers who followed Ashoka. Hereditary empires live and die by the quality of their leadership. The later Maurya kings lacked the administrative skill, political vision, and personal authority needed to hold together an empire of this scale.
As central control weakened, regional powers rushed to fill the vacuum. Kashmir broke away under Jalauka. Gandhara asserted independence under Virasena. Vidarbha separated. The Satavahanas, who would eventually build their own powerful dynasty in the Deccan, likely established independent power during this period as well.
Even within the empire’s core territories, the divided reigns of Dasharatha and Samprati showed that the Maurya state no longer had the internal cohesion to function as a single unit. Provincial loyalty, which had always been more personal than institutional, dissolved once a strong emperor was no longer there to command it.
2. Oppression by Provincial Governors
H.C. Raychaudhuri pointed to the tyrannical behavior of provincial administrators as a significant factor in the empire’s unraveling. The Divyavadana records two separate uprisings at Taxila — one during Bindusara’s reign and one during Ashoka’s — and in both cases, the people’s grievances were directed not at the emperor himself but at corrupt local officials:
“We are not against the prince, nor against King Bindusara — it is the wicked ministers who oppress us.”
Ashoka’s own Kalinga inscription acknowledges this problem. Addressing senior officials in Kalinga, he explicitly warned against arbitrary detention or mistreatment of citizens. To keep such abuses in check, he instituted a system of imperial inspections every five years.
That system worked while Ashoka was alive. After his death, it didn’t. Provincial officials grew more autonomous, less accountable, and more exploitative. The Garga Samhita’s description of Shalishuka — “he crushes the realm, proclaiming righteousness while practicing unrighteousness” — suggests that abusive governance eventually became official policy. When people suffer under tyranny long enough, they stop identifying with the state that oppresses them. That’s exactly what happened across the Maurya periphery.
3. Economic Strain
Some historians have pointed to economic pressures as a contributing factor. The later Maurya period saw significant fiscal stress. Taxes were raised and extended to new categories — even performers and courtesans were taxed. The punch-marked coins from this period show considerable debasement, suggesting the treasury was under strain.
Romila Thapar has noted that the Maurya period was when taxation first became the state’s primary revenue mechanism. As the economy grew and state functions expanded, higher taxes were inevitable. But weakening central control likely led to greater currency debasement, especially in territories drifting toward independence.
Recurring famines also disrupted the economic balance. The Sohgaura and Mahasthan inscriptions — among the earliest Indian administrative records — mention grain storehouses established for famine relief, indicating that food insecurity was a real and recurring concern.
Ashoka’s legendary generosity, extensively described in Buddhist texts, may have drained the treasury. The Divyavadana’s accounts of his donations are corroborated by multiple Buddhist sources. However, most historians treat economic causes as secondary. There’s no hard evidence that the Maurya economy was in fundamental collapse — archaeological evidence from Hastinapur and Shishupalagarh actually suggests material prosperity in the Maurya period.
4. Rejection of Foreign Cultural Influences
The art historian Niharranjan Ray offered a more culturally nuanced argument: that Pushyamitra’s coup reflected a popular backlash against the Maurya court’s adoption of foreign artistic and cultural elements. Maurya court art, he argued, drew heavily on Persian and Hellenistic influences and was fundamentally different from the indigenous folk traditions seen at Sanchi and Bharhut.
Ray also argued that Ashoka’s prohibition of certain social customs alienated ordinary people. However, this theory has significant weaknesses. For a genuine popular revolution to succeed, there must be organized mass consciousness cutting across social strata. The evidence for such organized resistance in Maurya India simply doesn’t exist. And it remains unclear whether Ashoka’s successors even continued his social restrictions.
5. Over-Centralization of Administration
Romila Thapar identified over-centralization as one of the most structurally important causes of collapse. The entire Maurya system was built around the personal authority of the emperor. Senior officials were appointed by and answerable to the emperor, not to the state as an institution. Their loyalty was personal, not civic.
This arrangement worked brilliantly when the emperor was strong. When he was weak — or when the empire split between rival claimants — the administrative machinery lost its binding force. Officials who had held their positions through imperial patronage had no institutional reason to hold the empire together once that patronage disappeared.
Thapar also argues that the Maurya state lacked a coherent concept of “the state” as an entity distinct from the ruler — that there was no idea of a nation to which citizens owed loyalty beyond their loyalty to the king. This is a more contested argument. Kautilya’s Arthashastra actually contains a highly sophisticated theory of the state (the saptanga theory), and expecting modern nation-state consciousness in ancient India is arguably anachronistic. Similar critiques could be applied to virtually every ancient empire from Rome to China.
The over-extension argument is more straightforwardly compelling. The Maurya Empire was simply enormous — stretching from Afghanistan in the northwest to Bengal in the east, and deep into the Deccan peninsula. Maintaining control over this territory required flawless administrative coordination and strong imperial will. When the will weakened, the coordination collapsed, and distant provinces naturally drifted toward independence.
6. Court Intrigue and Internal Power Struggles
The Maurya dynasty had a history of violent succession going back to its very founding — Chandragupta’s seizure of power, Ashoka’s own reportedly bloody path to the throne. This culture of court intrigue didn’t disappear; it intensified as the empire weakened.
The Malavikagnimitra, a Sanskrit play by the great poet Kalidasa, gives us a revealing glimpse of Brihadratha’s court: two powerful factions had formed, one centered around the civilian ministers and another around the military commander. The tension between these factions was constant and irreconcilable.
Ultimately, the military faction won — but not through a legitimate transfer of power. Pushyamitra Shunga simply had the emperor killed in front of the assembled army and declared himself ruler. This was not a revolution driven by ideology or popular grievance. It was a coup driven by personal ambition.
7. Was Ashoka Responsible for the Decline?
This is perhaps the most emotionally charged debate in Maurya history, and it divides along two main lines.
The Anti-Brahmin Policy Argument
Mahamahopadhyaya Haraprasad Shastri argued that Ashoka’s religious policies effectively attacked Brahmin privileges — banning animal sacrifice disrupted Brahmin ritual authority; promoting Buddhism elevated a rival tradition; the appointment of dhamma-mahamatras (moral overseers) undermined Brahmin control over justice and social regulation. Shastri argued that Brahmin resentment, suppressed during Ashoka’s reign, eventually found expression in Pushyamitra’s coup.
H.C. Raychaudhuri systematically dismantles this argument. He points out that Ashoka never imposed a complete ban on animal sacrifice. He also notes that Brahmin texts themselves — particularly the Upanishads — contain strong critiques of sacrificial ritual. The Mundaka Upanishad explicitly compares sacrifices to broken boats.
The supposed “refutation of the earth-gods” (bhu-devas, a term sometimes applied to Brahmins) in Ashoka’s Rupa-Nath inscription was likely misread. Sylvain Lévi interpreted the passage to mean that Indians who were previously “distant from the gods” had now, through improved conduct, come closer to them — nothing anti-Brahmin about that at all. Ashoka’s own inscriptions repeatedly express respect for Brahmins and call for harmony among all religious traditions.
Furthermore, Pushyamitra’s own appointment as commander-in-chief under a Maurya emperor proves that Brahmins held high positions in the late Maurya state. There’s no evidence of systematic Brahmin-vs-Maurya conflict. Kalidasa’s Rajatarangini even describes warm relations between Kashmir’s ruler Jalauka and local Brahmin communities.
The Non-Violence Policy Argument
Historians including R.D. Banerji, R.K. Mukherji, D.R. Bhandarkar, Raychaudhuri, and N.N. Ghosh have argued that Ashoka’s embrace of ahimsa (non-violence) and dhamma-vijaya (conquest through righteousness) fatally weakened the empire’s military capacity, leaving it unable to respond to the Greek invasions that began pressing from the northwest after his death.
Bhandarkar argued that replacing military conquest with moral conquest may have been spiritually admirable but was politically catastrophic. Raychaudhuri suggested that Ashoka’s pacifism left the army demoralized and unprepared for the Yavana (Greek) threat.
But this argument also has problems. Ashoka never disbanded his army. His inscriptions make this clear. His Thirteenth Rock Edict explicitly warns frontier peoples and forest tribes that he retains the power to punish those who deserve it. There’s no evidence his military discipline declined. The Maurya army that existed when he died was still formidable.
If Ashoka had pursued his grandfather’s iron-and-blood policy instead, the empire might have lasted somewhat longer — but no empire lasts forever, and the structural weaknesses outlined above would have eventually brought it down anyway. What Ashoka did achieve, by contrast, was something more enduring: a moral and cultural influence that spread Indian civilization across Asia, an influence that persisted for centuries and whose echoes remain visible today, more than two thousand years later.
The Bigger Picture: Structural Fragility of Ancient Empires
Historians sometimes expect ancient empires to behave like modern nation-states, with institutional continuity, civic nationalism, and self-sustaining administrative systems. The Maurya Empire wasn’t that, and it couldn’t have been. It was a personally administered empire in which the emperor’s individual qualities were the primary binding force.
The real marvel isn’t that it fell — every empire falls eventually. The real marvel is that it was built at all, and that it held together as long as it did. Under Chandragupta, Bindusara, and especially Ashoka, the Maurya state achieved something unprecedented in South Asian history: a single political authority governing virtually the entire subcontinent.
When Brihadratha fell to Pushyamitra’s sword around 185 BCE, that experiment ended. In its place rose the Shunga dynasty in the north and the Satavahana dynasty in the Deccan — smaller, more regionally focused states that would carry Indian civilization forward in different directions.
The legacy of the Maurya Empire, however, proved impossible to bury. Ashoka’s edicts, carved in stone across the subcontinent, still stand. His dhamma-chakra (wheel of righteousness) sits at the center of India’s national flag today. The empire’s administrative vocabulary, its road networks, its urban planning traditions — all left marks that shaped South Asian civilization for millennia.
Empires collapse. Civilizations endure.
