A dynasty of Shi'i judges who governed the richest port in Syria for forty years, and whose library was the most famous thing about them and the thing that did not survive them.

1070The qadis stop remittingreform
The Banu Ammar, Fatimid-appointed judges of a Shi'i city, simply stopped sending Tripoli's revenue to Cairo and began governing on their own account, as central Fatimid authority collapsed across Syria. There was no rising, no declaration and no battle — the judicial office they already held expanded until it was the state, and they went on naming the Fatimid caliph in the Friday prayer for decades after they had stopped obeying him.

Raymond of Saint-Gilles built a castle on the hill above the city and sat in it. The emirate was not stormed but strangled: it kept its walls and its fleet and lost its countryside, its revenue and its ability to feed itself, over seven years.

The last Ammarid left his own besieged city to ask the Seljuk sultan and the Abbasid caliph for an army. He was received with honour, given nothing, and could not get back: a Fatimid governor took over the city in his absence and surrendered it the following year. The emirate ended with its ruler alive and elsewhere.

1109The fall of Tripolisiege
A Genoese fleet and Baldwin I of Jerusalem took the city after the Fatimid governor who had replaced Fakhr al-Mulk the year before could not hold it either. Seven years of blockade ended in the County of Tripoli, and a working state with judges, a library and harbour dues was replaced rather than merely conquered.

The judges take the city
Drafted from Wilson, Medieval Syria and the Onset of the Crusades: The Political World of Bilad al-Sham 1050-1128 (2023)formation
In the middle of the eleventh century the Fatimid state came apart. A famine
and a currency collapse in Egypt under al-Mustansir, a Turkish and Berber
soldiery fighting each other in Cairo, and a general withdrawal of Fatimid
authority from Syria left the coastal cities to whoever was standing in them.
In Tripoli that was the qadi. The Banu Ammar were the city's judges, appointed
under Fatimid authority to a Shi'i city they belonged to, and around 1070 they
stopped remitting the revenue and began governing on their own account. There
was no rising, no declaration and no battle. The office simply expanded until
it was the state.
It is worth setting beside the other secessions of the period, because it does
not look like any of them. The Tulunids and the Ikhshidids were military
governors who kept their armies and stopped sending money. The Samanids were
appointed governors who inherited an empire. The Banu Ammar were civilians —
lawyers holding a religious office — and they went on naming the Fatimid caliph
in the Friday prayer for decades after they had stopped obeying him, because
the authority they had was the authority he had given them.
What they had instead of a tribe was money. Tripoli was the wealthiest port on
that coast: sugar and silk from the plain behind it, and the customs of a
first-rank Mediterranean harbour. So they hired their soldiers, which is what a
state with a revenue and no manpower does. It worked for forty years and then
it was the thing that killed them, because a bought army cannot be paid by a
city that has lost its countryside.
The House of Knowledge
Drafted from Wilson, Medieval Syria and the Onset of the Crusades: The Political World of Bilad al-Sham 1050-1128 (2023)peak
The thing the Banu Ammar are remembered for is a library.
The Dar al-Ilm at Tripoli was founded by the family in the later eleventh
century on the Fatimid model: an endowed institution with copyists on the
payroll, open to scholars, collecting across the disciplines rather than only
in law and hadith. A dynasty of judges spent its surplus on the one kind of
institution judges understand, and it worked — the city became a place scholars
in the eastern Mediterranean had reason to travel to.
The numbers nobody can use
Every later account gives a figure for the number of volumes, and the figures
are enormous and wildly inconsistent with one another.
They are not competing measurements. They are a literary convention about
destroyed libraries, of the kind that also attaches to Alexandria and to
Cordoba, and the sensible thing is to notice that the tradition insists the
collection was vast and to decline to say how vast. Picking one of the numbers,
or splitting the difference, would produce a fact that nobody ever recorded.
How it ended, on three accounts
What is not in doubt is that the library existed, that it was among the notable
collections of the Islamic Mediterranean, and that it did not survive 1109.
How it was lost is contested in the medieval sources and remains so. One line
of report has the Franks burning it deliberately after the city fell. Another
has it destroyed in the general sack, which was thorough. A third has it
already broken up and dispersed during the seven years of blockade, when a
besieged city was selling whatever could be sold.
The three accounts are not reconcilable and the question is probably not
answerable. What they agree on is the date.
What a family of lawyers left
The Banu Ammar founded no religion, adapted no script, and no later state
claimed to continue them. By the ordinary measures of influence they registered
nothing at all.
They also endowed the most important research collection on that coast, in a
city they had taken over by simply continuing to do their jobs after the
government above them stopped functioning, and it was the most consequential
thing they did. It is worth being clear that these two statements are about the
same people, and that the second is the one a reader should keep.
The letters that did not work
Drafted from al-Qalanisi, The Damascus Chronicle of the Crusades (1932)contraction
Tripoli was besieged for seven years. Its lord spent most of that time writing
to other Muslim rulers asking for an army, and Ibn al-Qalanisi — who was in
Damascus, receiving some of those letters at second hand — records what came of
it.
The sally that worked
It did not begin badly. In September 1104 Fakhr al-Mulk ibn Ammar went out of
the city with his own askar and the town levies and attacked the castle
Saint-Gilles had built facing Tripoli to blockade it.
The garrison was taken by surprise and killed. The place was plundered, set on
fire and reduced to ruins, and Fakhr al-Mulk came back the same day with a great
quantity of weapons, money, rich stuffs and silver.
A besieged city had destroyed its besiegers' fortress and looted it. On the
strength of that alone Tripoli could reasonably expect to hold — if anyone came.
The letters
Nobody came, and the chronicle's account of why is a study in how a frontier
gets abandoned by people who all sincerely mean to help.
Letters and envoys arrived constantly at Damascus from Fakhr al-Mulk, asking for
aid against the Franks besieging his city, urging that every available soldier be
sent to relieve his distress. The atabeg Zahir al-Din was seized by an illness at
exactly that moment, grew worse, and became consumed with worry about what would
happen to his own family, his men and his subjects if he died.
There were two amirs, Sukman ibn Ortuq and Jikirmish of Mosul, who had made a
formal compact with each other to prosecute the holy war and aid the Muslims.
Fakhr al-Mulk's letters reached them too, urging them to hurry. Zahir al-Din,
meanwhile, was inviting Sukman to Damascus for a different reason — to nominate
him as successor and hand him the defence of the city.
Everyone was corresponding. Everyone had prior business. The compact to fight the
Franks existed, in writing, between men who were at that moment arranging the
succession of a third city three hundred kilometres inland.
Going in person
By the spring of 1108 the situation had become critical — the siege, its length,
the long watch for reinforcements, and what the chronicle calls the continued
procrastination in sending assistance.
So Fakhr al-Mulk left. He went to Baghdad himself, to put the case to the caliph
and the sultan in person.
He was received. Magnificent robes were bestowed on him by the caliph and by the
sultan both. Then he came back to Damascus in early August 1108, stayed a few
days, and set out with a troop of Damascene cavalry attached to his own — not to
Tripoli, but to the port of Jabala, which gave him its allegiance.
He had gone to the centre of the Islamic world to ask for an army and had been
given clothes.
What happened at home
While he was away, the people of Tripoli sent to al-Afdal in Egypt and asked the
Fatimids for a governor — with ships, grain and provisions.
The governor came. Sharaf al-Dawla arrived by sea with the grain, established
himself in the town, and then arrested every partisan and officer Fakhr al-Mulk
had left behind. Their stores, his equipage and his furniture were put on ships
and sent to Egypt.
The city did not fall to the Franks that year. It changed sides, to a different
Muslim power, because that power sent food and the others sent letters.
Fakhr al-Mulk ibn Ammar was still alive, still lord of somewhere — Jabala, for a
while — and no longer lord of Tripoli, which he had left in order to save it.
Seven years and a journey
Drafted from Barber, The Crusader States (2012)end
Raymond of Saint-Gilles arrived in 1102 and did not try to storm Tripoli. He
built a castle on the hill above it — Mount Pilgrim, which Arabic writers call
Qal'at Sanjil after him and which is still standing over the modern city — and
occupied the plain. The city kept its walls, its harbour and its fleet, and
lost everything that made those worth having. It was a blockade conducted at
the pace of a lease.
Raymond died in 1105 with the siege unfinished. It went on.
By 1108 the last Ammarid had a city that could not feed itself and a bought army
he could no longer pay, and the appeals for relief had produced ceremonial robes
and no soldiers. Tripoli passed to a Fatimid governor who arrived by sea with
grain while its own lord was away looking for help.
The Fatimids held it for a year. In July 1109 a Genoese fleet and Baldwin I of
Jerusalem finished it.
What replaced the emirate was the County of Tripoli, and that is the sentence
worth slowing down on. The Crusader states are usually written about as
arrivals. They were also replacements, and the things they replaced were
working states with judges, libraries, harbour dues and a foreign policy.
Fakhr al-Mulk never got back. He was given Jabala on the coast for a time, lost
it, and ended his life in the Seljuk east as a pensioner of the sultan he had
gone to ask for help.
Eight days
Drafted from al-Qalanisi, The Damascus Chronicle of the Crusades (1932)afterlife
Ibn al-Qalanisi was writing in Damascus while this was happening, and his
account of the last two years of Tripoli is a record of help that was real, was
promised, was dispatched, and arrived at the wrong place or the wrong time.
By 1108 the situation in the city was, in his words, critical: the siege had
gone on too long, the watch for reinforcements had gone on too long, and the
sending of assistance had been continually put off. Fakhr al-Mulk's own
correspondence had already failed to move Damascus, so he went to Baghdad
himself and put the case to the sultan directly.
The relief that went to Mosul instead
He was received with honour, and the sultan agreed to the request in full: a
number of the great amirs were ordered to go back with him and relieve the
city.
The instruction that decided the whole thing came inside the same order. The
army detailed to go with him was to make a brief halt on the way, at Mosul,
and take the city out of the hands of the amir holding it.
Nobody came to Tripoli. Fakhr al-Mulk was kept at the sultan's court until he
lost patience, and at the end of August he went to Damascus instead. He had
been away four months and the relief he had been granted had been folded into
somebody else's quarrel over Mosul.
The fleet
While he was away a Fatimid governor arrived by sea and took over the defence.
Egypt then did what Egypt was capable of doing when it chose to.
The fleet it sent was, Qalanisi says, the largest the Egyptians had ever
dispatched, in numbers of men, of vessels, of equipment and of provisions:
enough food, men and money to hold Tripoli for a year, and to reinforce the
other coastal towns as well.
It reached Tyre on the eighth day after Tripoli fell.
The ships stayed on the coast a while and distributed the supplies among the
other ports. The people of Tyre, Sidon and Beirut begged the fleet to remain,
explaining their condition and their inability to fight the Franks on their
own, and it could not stay; when the wind was right it sailed for Egypt.
What was left to be
Tripoli fell in July 1109 after seven years of blockade. Within the year the
Franks had moved on to the next place and were negotiating with Damascus over
who got what share of the Biqa' harvest.
Fakhr al-Mulk never came back. He was given Jabala on the coast for a time,
lost that too, and ended as a pensioner in the Seljuk east, of the court he had
travelled a thousand kilometres to ask for an army.
The judges of Tripoli had governed for thirty-nine years on money, diplomacy
and the prestige of an office, without a tribe or an army of their own. All
three worked until the moment when what was needed was soldiers standing in a
particular place on a particular day, and then the whole structure came down in
the space of eight days' sailing.
The qadis of Tripoli, Fatimid-appointed judges of a Shi'i city, stopped remitting revenue to a Cairo in famine and mutiny and governed on their own account while continuing to name the caliph in the khutba.
Seven years after Raymond built his castle on the hill above the city, a Genoese fleet and Baldwin I finished the blockade — the last Ammarid having left for Baghdad to ask for an army and been unable to return.
