A highland dynasty from the mountains between Ghazna and Herat, long vassals of the Ghaznavids, who destroyed their former overlords and carried Muslim rule permanently into northern India.

1151The burning of Ghaznasiege
A vassal sacked its overlord's capital and was called Jahansuz, world-burner, for it. He did not keep the city; what he demonstrated was that it could be taken, and the generation after him took it and used it as the base for India. A hundred and ten years of a client growing stronger while its patron weakened produced exactly one outcome.

1192The second battle of Tarainbattle
Mu'izz al-Din had lost on the same ground the year before. He returned, won, and the Chauhan kingdom collapsed; Delhi fell the following year and his generals took Bihar and then Bengal. Where Mahmud of Ghazna had raided India for thirty years and annexed only the Punjab, this campaign installed garrisons and governors and left them there — the difference between a raid and a conquest that actually spread Islam into India.

The Indian provinces passed to the Turkish slave-generals holding them and never came back. Because the dynasty collapsed behind them within a decade, there was no metropole to secede from and nothing to fragment: the succession relocated the state rather than dividing it, and Aibak's line became the Delhi Sultanate.

The last place to convert
Drafted from Bosworth, Encyclopaedia Iranica · sourceformation
Ghur is the mountain country between Ghazna and Herat: high, poor, hard to
enter and harder to hold. It was still substantially pagan in the eleventh
century, four hundred years after the conquest of Iran, because nobody had
found it worth the cost of going in.
Mahmud of Ghazna went in around 1011 and imposed vassalage on the local
Shansabani chiefs. Their conversion, their entry into the political world of the
region, and their standing all date from that, and for a century and a half they
were exactly what such an arrangement produces: a client house supplying troops,
occasionally raiding, occasionally being punished.
The dynasty's beginning is therefore a range of a hundred and thirty years, and
the width of it is not carelessness. The local tradition carries the Shansabani
line back to the ninth century as chiefs of Ghur. The dynasty that appears in
the histories begins with Ghaznavid vassalage around 1011. One of those is a
lineage and the other is a polity, and no source settles which one the Ghurids
ought to be dated from.
The same thinness runs through everything else known about them. Nobody
publishes a figure for how much territory they held or how many people lived in
it, and the sources cannot agree on the name of the last sultan of Firuzkuh.
That is the ordinary condition of a mountain dynasty whose own archive was
destroyed with its capital.
The world-burner
Drafted from Bosworth, Encyclopaedia Iranica · sourceexpansion
In 1150 or 1151 Ala al-Din Husayn of Ghur sacked Ghazna. The chronicles say the
city burned for seven days, and he was called Jahansuz, world-burner,
afterwards.
The stated cause was vengeance: two of his brothers had been killed by the
Ghaznavids. The structural cause is duller and more decisive. Ghur was a
Ghaznavid client, and the Ghaznavid capacity to discipline its clients had
been going since Dandanaqan in 1040. A hundred and ten years of a vassal getting
stronger while its overlord got weaker produced exactly one outcome, and the
only surprising thing is how long it took.
Ala al-Din did not take Ghazna in the sense of keeping it — the Ghaznavids
returned, and then lost the city to Ghuzz Turkmen in 1163. What he did was
demonstrate that it could be done.
The generation after him did the rest. Ghiyath al-Din Muhammad held Firuzkuh and
Khurasan; his brother Mu'izz al-Din took Ghazna in 1173 and used it as the base
for India. Two brothers, one senior and one operational, neither of whom
supplanted the other — which is worth noting in a corpus where fraternal
arrangements almost always end the way the Buyids' did.
Mu'izz al-Din's India
Drafted from Jackson, The Delhi Sultanate: A Political and Military History (1999)peak
Mahmud of Ghazna had raided India for thirty years and annexed only the Punjab.
Mu'izz al-Din of Ghur, in about twenty, took the Gangetic plain and kept it.
He lost his first major engagement, at Tarain in 1191, against Prithviraja
Chauhan. He returned the following year, won on the same ground, and the
Chauhan kingdom collapsed. Delhi fell in 1193. His generals took Bihar and then
Bengal.
The difference from Mahmud is the point, and it is a difference of intent rather
than of scale. Mahmud's campaigns were extractive and cyclical: raid, remove the
proceeds to Ghazna, repeat. Mu'izz al-Din installed garrisons and governors and
left them there. That is the difference between a religion being carried and a
country being robbed, and it is why the Ghurid campaigns founded a Muslim state
in northern India and Mahmud's, which were larger and more famous, did not.
Then he was assassinated in 1206, near the Indus, with no son.
The Indian conquests were held by his Turkish slave-generals. Qutb al-Din Aibak
kept Delhi and Lahore, Bakhtiyar Khalji had taken Bengal, Yildiz held Ghazna,
Qabacha held Sind. Aibak's line, and then Iltutmish's, became the Delhi
Sultanate, which ruled northern India for three centuries and traced its
authority to a Ghurid appointment.
It is the only claim anybody ever made on the Ghurid inheritance, and it is a
very large one. A dynasty that held an empire for about thirty years produced a
successor state that lasted three hundred, in a country none of its founders had
been born in.
The instrument that did not walk away
Drafted from Jackson, The Delhi Sultanate: A Political and Military History (1999)peak
The slave-soldier story always ends the same way. The Abbasids bought Turks to
escape depending on provincial armies, and were being deposed by them at Samarra
within thirty years. The Samanids raised ghulams with no local landholding and
no claim of their own, and one of them walked off with Ghazna in 962 and founded
the dynasty that replaced them. The Ayyubids' purchased Bahriyya took the
sultanate in 1250. The Safavids broke the Qizilbash with a slave guard and were
in due course managed by it. It is the most reliable failure mode in the
military history of the region.
The Ghurids ran the same instrument and got a different result, and the
difference is worth setting out carefully, because it is why anybody remembers
them.
Mu'izz al-Din had no son. His Indian conquests — Delhi, the Gangetic plain,
Bihar, Bengal — were held by Turkish slaves he had bought, trained and raised
to command: Qutb al-Din Aibak at Delhi and Lahore, Bakhtiyar Khalji in Bengal,
Yildiz at Ghazna, Qabacha in Sind. When he was assassinated near the Indus in
1206, the instrument did exactly what the instrument always does. It took the
state.
What makes India different is what it took the state into. Aibak did not
carve a province off a surviving Ghurid empire; the empire went under within a
decade behind him, and there was nothing to secede from. What he held was a
conquest a thousand miles from the mountains that had launched it, with no
metropole left to answer to, a local revenue base, and an army of men in the
same position as himself. So the succession did not fragment the state. It
relocated it.
Aibak's line and then Iltutmish's became the Delhi Sultanate, which ruled
northern India for three centuries and traced its authority to a Ghurid
appointment. The slave system that dissolved every other state that used it is,
here, the mechanism by which a thirty-year empire produced a three-hundred-year
one.
The reason is not that the Ghurids managed their ghulams better. It is that
they died at the right moment, in the wrong place, and left their army holding
somewhere worth keeping.
A tower nobody could find
Drafted from Flood, Objects of Translation: Material Culture and Medieval "Hindu-Muslim" Encounter (2009)aside
Almost nothing written by the Ghurids survives. Firuzkuh was destroyed and the
dynasty's own records went with it, which is why so little can be said about how
they governed, how large they were, or even who the last of them was. What they
left instead is buildings, and the buildings say a good deal.
The largest is a brick tower sixty-five metres high standing in a river gorge
in the mountains of Ghur, at the confluence of the Hari Rud and the Jam,
surrounded by nothing. It was raised in the 1190s under Ghiyath al-Din, and it
is covered from base to summit in geometric brickwork, glazed turquoise tile
and Kufic and naskhi inscription — including, running around it, most of the
nineteenth sura, Maryam, which is the sura about the mother of Jesus.
Europe did not know it was there. It was reported in 1886 and then effectively
forgotten, and only came to general notice in 1957, when two French
archaeologists reached it. The site around it — a palace, fortifications, a
pottery kiln, a Jewish cemetery — is very probably Firuzkuh itself, the summer
capital the histories keep referring to and which nobody could point at for
seven hundred years. It leans, the river undercuts it, an earthquake in
2022 brought bricks down, and it has been on the list of world heritage in
danger since the year it was inscribed.
The other end of the empire built too, and built differently. At Delhi, from
1193, the Ghurid governor raised a congregational mosque and beside it the
minaret now called the Qutb Minar, and both were constructed substantially out
of the dismantled fabric of temples — columns, brackets and carved panels
reused as columns, brackets and carved panels. Flood's argument, against the
usual reading, is that reuse of this kind is not
adequately described either as pure iconoclasm or as pure economy: it was a
common medieval practice of appropriating the prestige of what was taken, done
by rulers on all sides of the period's religious lines, and reading it only as
a statement about religion imports a later quarrel into a twelfth-century
building site.
Two towers, then, two thousand kilometres apart, put up within a few years of
each other by the same family: one in an empty gorge that nobody visited for
seven centuries, one in a city that became the capital of northern India for
three. The dynasty that built them lasted about thirty years as an empire, and
this is the part of it still standing.
The road back from Khwarazm
Drafted from al-Juzjani, Tabakat-i-Nasiri: A General History of the Muhammadan Dynasties of Asia (1881)contraction
In 1204 Mu'izz al-Din went north to finish the Khwarazmshah. It was the one war
the Ghurids fought against an equal, and it took them about six months to stop
being an imperial power in Khurasan.
Muhammad Khwarazmshah heard the preparations coming and went home ahead of
them, calling in horse and foot from Khurasan and sending to the Gur Khan of the
Qara Khitai for help. Juzjani, who wrote for the Delhi sultans and remembered
the Ghurids fondly, gives the Ghurid army enough elephants to drink the Oxus
dry; his translator, who argues with him in the footnotes for a page at a time,
notes that the sober figures are large enough without the poetry. Mu'izz al-Din
reached the east bank of the river, arranged his elephants, and gave orders to
find a ferry for the morning.
The news that arrived that night was that Muhammad had come back, that the
sultan of Samarkand was with him, and that the Qara Khitai were on the road.
Mu'izz al-Din burnt his heavy baggage in the dark and started back along the
Oxus. He had already sat in front of Khwarazm itself for five days and given it
up — not enough siege equipment, not enough forage, a campaign that had gone on
too long. The Khwarazmians came after him at dawn. At Hazarasp the Ghurids
turned and fought; their right wing went first and the rest went with it, and
more of the elephants and the war material was lost in the pursuit.
They were still retreating when they reached Andkhud and found the road shut.
The Qara Khitai under Banjko of Taraz were across it, and closing from every
side. The Ghurids fought from dawn until the sun went down and darkness stopped
it. One account puts their dead at fifty thousand; another says they broke on
the first charge, which the translator thinks likelier than his author's version
and says so.
What happened during the night decided the rest. Husain ibn Kharmil, who
commanded the vanguard and had spent the afternoon urging the sultan to attack
again in the morning, looked at the fresh and countless enemy and at horses that
had walked from Khwarazm, and rode off towards Juzarwan with five thousand of
his own, and most of the men whose mounts were finished went too. At dawn Mu'izz
al-Din drew up what was left of the centre and his own slaves and started the
battle anyway. Juzjani says he stood until about a hundred horsemen remained,
that the arrows sticking in his canopy made it look like a porcupine, and that
he would not turn his head, until a Turkish slave called Ayaz Juki took hold of
his bridle and dragged him to the fort of Andkhud.
The Qara Khitai invested the fort and began cutting through the walls. What got
him out was the sultan of Samarkand, riding with the besiegers, who sent in word
that he did not wish a Muslim sovereign to be killed by unbelievers and that if
Mu'izz al-Din would surrender what was left of his elephants, his animals, his
treasure, his arms and his armour, that could be made to buy his life. He
agreed, and reached his own territory alive.
He had marched north to annex Khwarazm. He came back with a hundred horsemen,
having paid the contents of his baggage train for permission to leave. Khurasan
was gone, and it was not coming back; two years remained, and they were spent in
India.
Squeezed out
Drafted from Bosworth, Encyclopaedia Iranica · sourceend
Ghiyath al-Din died in 1203 and Mu'izz al-Din in 1206, and the state did not
survive both of them.
It had already lost the argument in the field. The Khwarazmians were by then the
strongest power in the east and the Qara Khitai still the protectors of
everything north of the Oxus, and after the two of them shut the road at
Andkhud the Ghurid claim to Khurasan was a claim and nothing else.
Then Mu'izz al-Din was assassinated near the Indus, with no son.
What went where
The Indian provinces went to the slave-generals within months and never came
back. Ghazna went to Yildiz, Sind to Qabacha, Delhi and Lahore to Aibak, Bengal
to the Khalji.
What was left was Ghur itself: the mountains the dynasty had started in, held by
a succession of short-reigned sultans whom the sources record so
inconsistently that the name of the last one cannot be established. Firuzkuh
fell to Ala al-Din Muhammad of Khwarazm in 1215, and the summer capital, its
palace and its archive went with it.
The shape of it
Roughly thirty years elapsed between the Ghurids taking Ghazna and losing
Firuzkuh. It is one of the shortest imperial careers anybody has had, and it
produced one of the longest-lasting successor states.
The reason those two facts belong in the same sentence is that they have the
same cause. An empire held together by one man's appointments, in country that
could not support it, at the far end of a march from mountains that produced
nothing, was never going to outlive the man. What it could do — and what it did
— was put able men in charge of a rich country a thousand miles away and then
die before it could recall them.
Bought at Delhi
Drafted from al-Juzjani, Tabakat-i-Nasiri: A General History of the Muhammadan Dynasties of Asia (1881)afterlife
The Ghurid empire lasted about thirty years. The state its slaves founded lasted
three hundred, and the fullest account of how that happened was written by a man
who had grown up in Ghurid country and ended his life at the court of a Ghurid
slave's descendant.
The transaction
Juzjani tells the story of Iltutmish's purchase in some detail, because by the
time he was writing it had become the origin story of the dynasty he served.
Shams al-Din Iltutmish was a Turkish slave who had been taken to Ghazna and
could not be sold there, because an order had been issued that nobody was to buy
him. He was moved to Bukhara for three years, brought back to Ghazna for
another, and still could not be purchased.
Then Qutb al-Din Aibak — who was himself, at that point, still a slave — came to
Ghazna after the Gujarat campaign, heard the story, and asked Sultan Mu'izz
al-Din for permission to buy him.
The sultan's answer is the sentence the whole afterlife turns on. Since a
command has been issued that he should not be purchased at Ghazna, let them take
him to the city of Delhi, and there he can be purchased.
So Aibak left an officer behind with instructions to bring the two slaves down
to Delhi on his return, and bought Iltutmish there.
And then the recommendation
It gets better. Some years later Mu'izz al-Din sent for Iltutmish, gave him a
special robe of honour, ordered his deed of manumission drawn up — and told
Aibak, in Juzjani's rendering: treat Iltutmish well, for he will distinguish
himself.
Set that beside what happened next. Mu'izz al-Din was assassinated in 1206.
Aibak took Delhi and Lahore and reigned until he died at Lahore, whereupon the
commander of troops and the lord justice of Delhi wrote to Iltutmish. Iltutmish
took the sultanate and is, by common consent, the real founder of the Delhi
Sultanate — the man who consolidated it, obtained investiture from Baghdad for
it, and made it a state rather than a garrison.
The Ghurid sultan personally authorised the sale of that man to that buyer, in
that city, and then recommended him.
The historian
Minhaj al-Din Juzjani was from a family of scholars in the highlands of Herat.
His maternal ancestors had held the qadi-ship of the fortified town of Tulak,
in the Ghurid mountains, by diploma from the caliph, and he kept the documents.
He was, in every sense that mattered to him, a man of Ghur.
He wrote the Tabaqat-i Nasiri at Delhi and dedicated it to Sultan Nasir al-Din
Mahmud Shah, a grandson of Iltutmish — who gave him a cloak, a turban and a
caparisoned horse for it, and a stipend afterwards for a verse account of a
campaign. The commander of that campaign, Balban, gave him the revenues of a
village.
So the standard history of the Ghurids was written by a Ghurid, in India, for
the grandson of a slave his sultan had once given orders about, and paid for
with a village in the Punjab.
What that is an afterlife of
Nothing else the Ghurids did survives in this way. The dynasty produced no
literature anyone kept, no administrative tradition, no line of successors in
its own country. Its capital is a tower in a gorge that Europe could not locate
for seven hundred years.
What it produced was three or four capable men whom it had bought as boys, and a
country to put them in. That turned out to be enough — and the man who wrote it
all down had to move two thousand kilometres to be somewhere it still mattered.
Mahmud of Ghazna campaigned into Ghur and imposed vassalage on the Shansabani chiefs, whose conversion and political standing both date from that subordination.
Mu'izz al-Din died without a son and his Turkish slave-generals kept the Indian conquests; Qutb al-Din Aibak held Delhi and Lahore, and the line that followed him ruled northern India for three centuries.
