The contracted Mauryan rump a general took by killing his own emperor, that fought off a Greek army at the gates of its own capital, revived the old paramount's horse-sacrifice to prove the point, and spent its last decades as short reigns and palace murders before its own chief minister did to it exactly what its founder had done to the Mauryas.

185 BCPushyamitra's coupsuccession crisis
The Mauryan commander-in-chief killed his own emperor at a troop review and took the throne over a contracted rump of the empire he had served - Magadha and the Gangetic heartland, extending south only as far as the Narmada, with none of the Mauryan north-west or Deccan attached to it.

The dynasty's gravest external test in a hundred and twelve years of existence was fought off at the very approaches to its own capital, by an army that had spent most of the preceding decades on the defensive against exactly this kind of threat and had never before had to fight one this close to home.

A contracted throne
Drafted from Smith, The Early History of India, from 600 B.C. to the Muhammadan Conquest (1904)formation
Bana, writing at Harsha's court eight centuries later with access to records
no longer known to survive, gives the coup its own line: "reviewing the
whole army, under the pretext of showing him his forces, the mean general
Pushpamitra crushed his master, Brihadratha the Maurya, who was weak of
purpose." Pushyamitra imprisoned the dead emperor's minister, took the
throne for himself, and founded the dynasty history knows as the Shungas.
What was left to inherit
The empire Pushyamitra took was not the one Ashoka had ruled. Pataliputra
remained the capital, and the central Gangetic provinces — what would
later be called Bihar, Tirhut, and the United Provinces around Agra and
Oudh — still answered to it, with authority extending south as far as the
Narmada river. The north-west, lost piece by piece since Ashoka's death,
was gone; there is no evidence the Shungas, any more than the last weak
Mauryas before them, ever exercised authority in the Punjab.
An epigraphic footnote and a literary witness
Almost nothing survives from the dynasty's own hand. A Barhut inscription
opens with the formula "during the reign of the Sungas," which is the one
contemporary epigraphic confirmation that the dynastic name itself was
current at the time rather than a later label imposed by chroniclers.
Beyond that single line, what is known of the Shungas comes overwhelmingly
from later literature — the Puranas, and Bana's romance composed for an
entirely different king's court centuries afterward — rather than from
anything the dynasty inscribed about itself.
A general who had killed his own emperor took a kingdom already reduced
from its Mauryan extent, kept the old capital, and left almost no record of
his own reign except the word of the dramatist and the chronicler who came
long after him.
Two invasions at once
Drafted from Smith, The Early History of India, from 600 B.C. to the Muhammadan Conquest (1904)peak
In the later years of Pushyamitra's reign, the dynasty he had founded by
killing one emperor came close to being unmade from two directions at once.
From the west
Menander, a relative of the Bactrian king Eucratides and ruler of Kabul and
the Punjab, set out to match Alexander's own exploits and advanced deep
into Indian territory with a formidable army. He annexed the Indus delta
and the peninsula of Kathiawar, occupied Mathura on the Jumna, besieged the
town of Madhyamika near modern Chitor in Rajasthan, invested Saketa in
southern Oudh — and, by the time his advance was finally checked, was
threatening Pataliputra itself.
From the east
At close to the same moment, Kharavela, the Jain king of Kalinga on the Bay
of Bengal coast, invaded Magadha from the other direction. His own
inscription, cut into the rock of the Hathigumpha cave at Udayagiri and
badly damaged but still legible in outline, claims he humbled the king of
Magadha and advanced as far as the Ganges. Whatever ground he actually
took, the advantage does not appear to have lasted, and the campaign
reads, from what survives of the record, as a raid on the eastern frontier
rather than a lasting conquest.
What held
Menander's was the graver threat, and it was repelled only after a severe
struggle — Pataliputra's approaches fought over directly rather than a
distant province being quietly ceded. The Greek king retired to his own
territory, though he appears to have kept his western Indian conquests for
some years afterward rather than surrendering them along with the eastern
campaign. It was, as it turned out, the last time a European general would
attempt to conquer India by land. Every invasion that followed, down to
Vasco da Gama's arrival by sea in 1502, came from the water rather than
across the passes — which makes the defence of Pataliputra in the 150s BC
the final chapter of a story that had opened with Alexander at the
Hyphasis a century and a half before, and the Shungas, for one campaign,
the ones who closed it.
The horse
Drafted from Smith, The Early History of India, from 600 B.C. to the Muhammadan Conquest (1904)peak
Having survived a Greek army at his own gates, Pushyamitra — by now an old
man, with a grown grandson already serving in the field — set out to make
the survival formal. He revived the ashvamedha, the horse-sacrifice, an
ancient rite that only a paramount sovereign was entitled to perform, and
whose performance was itself the proof of the claim.
How the rite worked
A horse of a particular colour was consecrated and turned loose to wander
for a year. Wherever it went, the ruler of that territory faced a choice:
fight the army following behind it, or submit. If the horse's guardians
secured submission everywhere it wandered, its owner returned in triumph
with the defeated rulers in his train, and the horse was ceremonially
sacrificed at a great festival marking the claim as proven. If they
failed, the whole enterprise ended in humiliation rather than glory.
The grandson's part
Command of the guard following the horse was given, at least nominally, to
Pushyamitra's young grandson Vasumitra — the same prince who had served in
the field during his father Agnimitra's viceroyalty in the southern
provinces. Vasumitra encountered and routed a band of Yavanas, western
foreigners, who challenged the horse on the banks of the river Sindhu,
between what is now Bundelkhand and the Rajputana states — quite possibly
a detachment of the same Greek force that had besieged Madhyamika during
Menander's invasion, still operating in the region rather than having
withdrawn entirely.
What the rite settled, and for whom
With the Yavanas defeated and no other rival left standing, Pushyamitra
carried out the sacrifice at his capital with the magnificence tradition
demanded, and — at least in the account preserved through Bana's drama —
was formally justified in his claim to rank as paramount power of northern
India. It was a claim resting entirely on recent military success rather
than on birth: a general who had killed his own emperor to take the throne
proved his right to it, in the end, the same way he had taken it — by
force, formally staged and ritually confirmed, with his own grandson doing
the fighting that made the ceremony more than theatre.
A reputation on loan
Drafted from Smith, The Early History of India, from 600 B.C. to the Muhammadan Conquest (1904)aside
Pushyamitra has a reputation, in a certain strand of later Buddhist
writing, as a persecutor who destroyed monasteries and put a price on the
head of every Buddhist monk in his kingdom. Smith, weighing the sources
available to him, finds the specific charge against Pushyamitra himself
unproven — but the reason it is worth examining at length is not that the
individual claim is safe to dismiss. It is that the question of whether
religious persecution happened at all in ancient India was, in his own
day, a live scholarly argument, and Pushyamitra sits right at the middle of
it.
A debate about the wrong default
Rhys Davids had argued that organised religious persecution was essentially
foreign to Indian civilisation before the Muslim conquests — a claim
Hodgson, Sewell and Watters all disputed with specific counter-examples.
The case against Pushyamitra by name does not hold up well under that
scrutiny. But the case that persecution never happened at all holds up
considerably worse, once other well-attested instances are set beside it.
The instances that are not in doubt
Shashanka, the king of Bengal whose murder of Harsha's brother sits at the
opening of the following century's history, is independently and
repeatedly described as a Buddhist-persecuting king by Xuanzang — a
near-contemporary witness with no obvious motive to invent the charge.
Outside India entirely, Tibetan chronicles record a persecution of
Buddhism under King Langdarma around 840 AD, and the Khotan annals
preserve a comparable episode. In southern India, a documented persecution
of Jainism is recorded independently of any of the northern material.
What that comparison is for
None of those cases makes the specific accusation against Pushyamitra any
more credible on its own evidence. What it does is correct the shape of
the question. The debate was never really about whether an Indian king
could persecute a religious minority — plainly some did, in well-attested
cases spanning six centuries and three regions. The debate is about
whether this particular accusation, against this particular king, made
by sources writing well after his death and with their own reasons to
resent the dynasty that killed a Buddhist-tolerant emperor to found itself,
is one of the true cases or one of the invented ones.
Pushyamitra's reputation for persecution turns out to be a live question
precisely because the category it belongs to is real. That is a harder
thing to settle than either "the Shungas never touched Buddhism" or "the
Shungas destroyed it" — and it is the honest answer the evidence actually
supports.
A queen who was not
Drafted from Smith, The Early History of India, from 600 B.C. to the Muhammadan Conquest (1904)end
Pushyamitra died about five years after Menander's retreat, having reigned
long and eventfully, and was succeeded by his son Agnimitra — the same
prince who had governed the southern provinces as viceroy throughout his
father's wars. Agnimitra reigned only a few years. What followed was a
sequence of short, disordered reigns that reads less like a dynasty than
like a list of casualties.
The actor's death
Sujyeshtha, probably Agnimitra's brother, succeeded him and was followed
seven years later by Vasumitra — the same grandson who had guarded the
sacrificial horse against the Yavanas as a young man. After Vasumitra came
four reigns so short that all four together total only seventeen years,
strong evidence of a court in continual crisis. One incident from this
period survives in specific enough detail to have been remembered on its
own merits: Sumitra, another son of Agnimitra, "inordinately devoted to
the stage," was surprised in the middle of a performance by his own
attendants, absorbed among his favourite actors, when a man named
Mitradeva "severed his head with a scimitar, as a lotus is shorn from its
stalk."
The tenth king
The ninth king, Bhagavata, is credited with a long twenty-six-year reign
about which nothing else is recorded. The tenth and last, Devabhuti — also
given as Devabhumi — is remembered only for licentious habits and for the
manner of his death: killed while engaged in what Bana's account calls a
discreditable intrigue.
The plot that ended him had been arranged by his own Brahmin minister,
Vasudeva Kanva, who by this point was already running the state in all but
name behind a dissolute figurehead. Vasudeva had a slave-woman disguised
as the queen sent to the king "in a frenzy of passion" — Bana's own
phrase — and it was she, at the minister's instance, who took his life.
The name Mitradeva shares
The man who had beheaded Prince Sumitra mid-performance, years earlier, was
very probably a member of the same family that now finished the dynasty
off: Mitradeva and Vasudeva Kanva both belonging, on the evidence of the
name, to the house of the Kanvas — meaning the same family had been
positioned close enough to the Shunga throne to assassinate a prince and,
a generation later, to murder the last king who sat on it and take the
throne for themselves. Contemporary opinion, Smith notes, held that the
later Shunga kings held little real power and were puppets in Brahmin
ministers' hands — an arrangement not unlike the Maratha rajas' later
relationship to their own Peshwas. The dynasty founded by an army
commander who killed his emperor at a troop review ended a hundred and
twelve years later, murdered in bed by the family that had been quietly
running it for some time already.
Pushyamitra, the Mauryan commander-in-chief, killed the last emperor at a review of the troops he commanded and took the throne himself. Nobody invaded and nothing was conquered.
Vasudeva Kanva, the Brahmin minister already running the state behind its last dissolute king, had him murdered and took the throne himself - the fourth ruling house of Magadha in a row to begin with a trusted subordinate turning on the man he served.
