The last Yemeni dynasty to rule Yemen: a family of highland landowners who picked up the Rasulid state as it fell, spent sixty-three years building in it, and were killed by an expedition sent from a sultanate that had itself already ceased to exist.

1504The Amiriyya at Rada'reform
Amir II finished a madrasa at Rada' whose domes and painted interior have no real precedent in Yemen, and which is the reason this dynasty has a modern historian at all. It marks the point at which a family of provincial landowners was governing as a state that expected to last, thirteen years before it did not.

1517The expedition from a dead empirebattle
A Mamluk force sent from Cairo to contest the Portuguese in the Red Sea turned inland instead, defeated Amir II and killed him. By the time it did so, Selim had destroyed the Mamluk Sultanate in Egypt and Syria: the army that ended Yemeni self-rule was acting for a state that no longer existed, and it transferred its allegiance to the Ottomans afterwards.

Picking up the state
Drafted from Bosworth, The New Islamic Dynasties: A Chronological and Genealogical Manual (1996)formation
The Rasulid sultanate did not fall to anybody. It came apart over about thirty
years of disputed successions, plague and a collapse in the revenue that had
held it together, until by the middle of the fifteenth century there were
several men calling themselves sultan and none of them governing much.
The Banu Tahir were landowners from Juban, in the highlands south of Sanaa. They
had been men of consequence under the Rasulids without being of the ruling
family, and through the 1440s they were among the parties fighting over what was
left. In 1454 two brothers, Amir and Ali, took what remained of the state and
ruled it jointly.
They did not conquer it. There was a state that had stopped working and a family
standing closest to it when it stopped, and the distinction matters: nobody
besieged Ta'izz and nobody deposed a Rasulid. The revenue failed, the succession
was fought over for thirty years, and at the end of it the men holding the
southern highlands were the men holding the country.
What the Tahirids picked up was smaller than what the Rasulids had had. The
Zaydi imams were back in the northern highlands and were not going to be
removed. Aden's customs, which had built the Rasulid state, were falling as the
Indian Ocean traffic found ways around them. This dynasty governed a reduced
country for sixty-three years, and what it did with them is more interesting
than the reduction.
The port that stopped paying
Drafted from Vallet, L'Arabie marchande: État et commerce sous les sultans rasulides du Yémen (626-858/1229-1454) (2010)expansion
Every polity in this region's thread from the Zurayids onwards has stood on the
same fact: that ships from India could not sail straight through to Egypt, so
Aden collected. The Tahirids inherited the collection and inherited it while it
was failing.
Some of the reasons were commercial and predate the Portuguese entirely. Jeddah
under the Mamluks had been drawing traffic north past Aden for decades, and
merchants who could clear their cargo closer to Cairo did. Some of it was
political: the Rasulid administration that had made Aden reliable — the fiscal
registers Vallet works from, the fixed and published dues — did not survive its
own state, and a port whose charges are unpredictable is a port that gets
avoided.
Then in 1498 Vasco da Gama came round the Cape, and within a decade Portuguese
squadrons were in the Arabian Sea trying to close the Red Sea mouth altogether.
So the Tahirids inherited a customs house that no longer worked like one. Their
actual money came increasingly off the highlands they had come from. What Aden gave them was a reason for other
people's fleets to take an interest in Yemen, which is what killed them.
The Amiriyya
Drafted from Porter, PhD thesis, University of Durham (1992)peak
In 1504 Amir II finished a madrasa at Rada'. It has two domes on a raised
platform, a facade of stucco panelling, and an interior painted in a way that
has no real precedent in Yemeni building, and it is still standing.
A building deserves a chapter here for a reason that is about evidence rather
than about architecture. The Tahirids left no fiscal archive of the kind the
Rasulids left, and the chronicle material for their sixty-three years is thin.
What they left was construction —
mosques, madrasas, cisterns and fortifications across the southern highlands —
and Porter's study of the dynasty is built on that as much as on the texts,
because the distribution of a dynasty's buildings is a reasonably honest map of
where its authority and its money actually reached.
Nobody has published an extent for the Tahirid state, and it would be a
fabrication to derive one. But the buildings are dated and located, and they
cluster in the southern highlands and along the routes to Aden and Zabid, and
they are absent from the north where the Zaydi imams were. That is not a
measurement. For the question of where these people actually governed, it is
better than one.
The other thing the Amiriyya records is intent. A family that had picked up a
collapsing state in 1454 was, fifty years later, building on the scale of a
dynasty that expected to be there in a century. It had thirteen years.
This orchard
Drafted from younger, The Commentaries of the Great Afonso Dalboquerque, Second Viceroy of India, Part IV (1884)contraction
In March 1513 a Portuguese fleet appeared off Aden. It was the first European
force ever to attempt the Red Sea, and its commander intended to take the port,
close the strait, and cut the spice route between India and Egypt at its neck.
Aden held.
How the assault failed
The account written up from the commander's own papers is candid about it,
because the failure was not the defenders' doing in the first instance. It was
the attackers'.
The boats grounded a crossbow-shot from the shore on shelving rock, so the men
had to wade in, and the musketeers soaked their powder doing it. They carried
the scaling ladders on their backs through the water and got them against the
wall anyway.
Then the ladders broke. Not under enemy action — under the weight of Portuguese
soldiers racing each other to be first up. The commander's own company put their
ladders up and swarmed them without waiting for orders; the ladders came down.
The men then ran to the next ladder along and broke that one too, and the
halberdiers sent to prop it up had their halberds smashed and were killed or
wounded under it.
One party did get onto the wall and planted a banner on a turret. Nobody could
reinforce them, because by then every ladder in the fleet was in pieces. The
commander's nephew, wounded and covered in blood, made his way along the
parapet to ask what to do, and was told: do not excite yourself, for this
orchard cannot produce any other kind of fruit than this.
They burst open an embrasure to let crossbowmen through. The defenders saw how
few men were on the wall, swarmed the opening, and filled it in with lighted
straw and earth and stones. A ladder was patched together out of the splinters
of the broken ones. It failed too.
The fleet withdrew, went into the Red Sea, found no water and no useful landfall,
and came back out having achieved nothing.
Why a successful defence was a catastrophe
The Tahirids had beaten off the most formidable naval power then operating in
the Indian Ocean, at their own richest port, and it did them no good at all.
What the attempt announced was that the Red Sea was now contested by a force
that came from the ocean rather than from Egypt or Arabia, and that the spice
route which had already been drifting away from Aden could now be cut at will by
somebody with better ships. Yemen's whole fiscal position depended on that route
touching its coast.
More immediately, it brought the fleets. The next year an Egyptian fleet took
most of the Yemeni ports — not Aden, which held again — and the Mamluk sultanate
began operating in the Red Sea as a matter of survival, because the Portuguese
threatened Egypt's revenue far more than they threatened Yemen's.
Four years later a Mamluk expedition sent into those waters against the
Portuguese would turn inland instead and destroy the dynasty that had held the
wall in 1513.
The defence of Aden was competent, and it was the beginning of the end. The
Tahirids were not conquered because they were weak at sea. They were conquered
because their coast had become strategically interesting to two empires at once,
and neither of those empires was going to leave it in the hands of a family of
highland landowners.
An army from a state that no longer existed
Drafted from Porter, PhD thesis, University of Durham (1992)end
The force that ended Yemeni self-rule had not been sent to Yemen.
Cairo had despatched a Mamluk expedition into the Red Sea to deal with the
Portuguese, who were raiding shipping and had attempted Aden. It was a naval
problem and the expedition was a naval answer to it. In Yemen the expedition
found a quarrel with Amir II instead — over supply, over money, over the
Tahirid refusal to be treated as a subordinate — and turned inland. It defeated
him and killed him in 1517, and took Sanaa and Zabid.
While it was doing that, Selim I destroyed the Mamluk Sultanate. Qansuh
al-Ghawri had been killed at Marj Dabiq in August 1516 and Tuman Bay was hanged
at Cairo in April 1517. The men who conquered Yemen were the army of a state
that had been abolished, and they found it out afterwards, and went over to the
Ottomans, who thereby acquired a country they had not fought for.
The conquerors were Mamluks, and they are named as such here even though the
result reads strangely: a state destroyed in 1517 by a state that itself ended
in 1517. Assigning the conquest to the Ottomans instead would be tidier and
would be false. The Ottomans acquired Yemen by inheriting the men who took it,
several months after the fact, without sending anybody.
What did not end in 1517 was the Zaydi imamate in the northern highlands, which
had outlasted the Sulayhids, the Ayyubids, the Rasulids and now the Tahirids,
and which took the Ottomans a century to subdue and another thirty years to lose
to. Its record is elsewhere in this region and carries no edge to this one. The
imams were not the Tahirids' heirs and did not claim to be. They were simply
still there, which in this country was the more durable achievement.
A hundred and thirteen years
Drafted from Bury, Arabia Infelix, or the Turks in Yamen (1915)afterlife
What replaced the Tahirids was not another Yemeni dynasty. It was a century of
somebody else's empire, and the interval is worth counting: from the killing of
the last sultan in 1517 to the point at which Yemen was governed from inside
itself again is a hundred and thirteen years.
The sequence, as a later British account sets it out, is short and almost
entirely about the coast.
Egypt came under Ottoman suzerainty in 1517 — the same year the expedition it
had sent killed the Tahirid sultan. In 1538 the Ottoman governor of Egypt
occupied the coastal towns of Yemen and laid the foundation of Ottoman dominion
there. The Portuguese took Aden in 1540. A Turkish admiral took it back. A
governor named Hasan Pasha eventually occupied the whole province in the
sultan's name, and that occupation lasted until 1630, when the Porte decided to
evacuate Yemen on account of its remoteness and the expense involved.
Yemen was then governed by a family descended from a sharif of Mecca, one of
whom took the title of imam.
The shape of it
Read that again with the dates removed and it is a familiar Yemeni pattern
running one more time.
An outside power arrives because the coast is valuable. It takes the ports
easily and the highlands with difficulty. It holds the country for as long as it
is willing to pay for it, discovers that Yemen costs more than it yields, and
leaves. What fills the space afterwards is not the dynasty that was there before
— that family is gone — but whoever in the mountains can raise men.
The Ayyubids did this in the twelfth century and left the Rasulids behind. The
Ottomans did it in the sixteenth and left an imamate behind. The Ottomans did it
again in the nineteenth. The variable is which empire; the constant is that the
highlands outlast it and the coast pays for it.
What the Tahirids left standing
The dynasty itself left very little in the way of institutions, having had
sixty-three years and no successor.
What it left was buildings. The madrasa the last sultan finished at Rada' in
1504 — domed, painted, unlike anything built in Yemen before it — was thirteen
years old when its patron was killed, and it is still there. A family of
provincial landowners who governed for two generations and were destroyed by an
army acting on behalf of a state that had already ceased to exist are remembered
mostly because of what they put up in a small highland town while they had the
money.
That is a thin legacy by the standards of the dynasties on either side of them.
It is also the last thing built in Yemen by a Yemeni government for a very long
time.
Two brothers of the Banu Tahir, highland landowners who had been men of consequence under the Rasulids, took what was left of a sultanate that had spent thirty years coming apart over disputed successions and falling revenue.
A Mamluk squadron sent into the Red Sea against the Portuguese turned inland instead, defeated and killed Amir II and took Sanaa and Zabid — months after Selim had abolished the sultanate that sent it.
