One of the oldest Malay sultanates, converted to Islam in 1474, plundered by Portugal and Aceh in turn, blockaded for decades by the Dutch over its tin trade, and broken by a Siamese invasion that cut its population from 180,000 to 6,000 within six years.

Malacca falls to PortugalCatastrophe
The fall of Malacca to a Portuguese conquest, and the exile and 1513 death of its last Malay sultan, ended the possibility of protection or precedence from the senior Malay court a Kedah prince had once travelled to for the royal regalia; a Portuguese account five years later described Kedah plainly as a tributary of Siam.

Fire and sword from TenasserimCatastrophe
A Portuguese force under Dioge de Mendoca Furtado, sailing down from Tenasserim toward Malacca, destroyed the towns of Kedah with fire and sword - proof that neither Siamese overlordship nor Kedah's own standing as a major tin port could shield it from a passing European fleet.

The Sultan led into captivityBattle
Aceh's Sultan Iskandar Muda, campaigning against the rulers of the Malay Peninsula, led Kedah's own Sultan Sulaiman Shah into captivity along with the ruler of Perak. Achinese influence over Kedah persisted for some years afterward.

1821
A population cut to a thirtiethCatastrophe
Siam invaded Kedah, forcing Sultan Ahmad Tajuddin Halim Shah to flee to Province Wellesley; the occupying Siamese administration divided the country into four parts under separate rulers, and within six years its population fell from 180,000 to 6,000. The sultan was not restored, under Siamese protection, until 1843.

A ruler converts
formationDrafted from Winstedt, History of Kedah (1920)
Long before it became a Muslim sultanate, Kedah was known to Arab
and Chinese traders alike as a mart for tin, its people Buddhist and
its politics shaped by the great powers around it - first Palembang
and the Chola kings, then the Javanese empire of Majapahit, all of
whom in turn claimed some suzerainty over it.
Kedah's own dynastic
annals, the Hikayat Marong Mahawangsa, record seven pre-Muslim
rulers bearing Sanskrit and Siamese titles before the line's eighth
ruler became its first Muhammadan king, taking the style Sultan
Muzaffar Shah.

A date fixed by two traditions
An Achinese account gives 1474 as the year of that conversion, and
the date is confirmed independently by a story in the Sejarah
Melayu, the Malay Annals, in which a Raja of Kedah travels to
Malacca to request the royal regalia from Sultan Mahmud Shah, the
last Malay ruler of Malacca before its fall to the Portuguese in
1511. Genealogically, Sultan Muzaffar Shah is always reckoned as the
great-great-great-grandfather of the Sultan Sulaiman Shah later
carried into captivity by Aceh in 1619 - a span of generations that
fits the 1474 date far better than the confused chronology of the
Annals themselves, which were repeatedly revised long after their
original composition.
A preface and a branching line
expansionDrafted from Winstedt, History of Kedah (1920)
Sultan Muzaffar Shah's own line did not pass down a single unbroken
chain. The Kedah Annals record three sons succeeding him in turn -
Muazzam Shah, who reigned from Kota Palas; a Raja Muhamad Shah; and
a Sulaiman Shah who ruled at Langkapuri, the old name for Kedah
itself - before the throne narrowed back to a single line through a
later Muhammad Shah and, by tradition, a Mansur Shah, down to Mahmud
Shah and finally the Sultan Sulaiman Shah whom Aceh would carry into
captivity in 1619.
A history written in a king's own reign
It was in the reign of Muazzam Shah, the second Muslim ruler of
Kedah, that the Annals themselves claim to have first been composed
a claim that, if true even of the work's original core, would make
them one of the oldest Malay chronicles of any kind.
Later hands
plainly reworked the text more than once: it carries interpolations
from as late as the seventeenth century, and its list of rulers was
extended long after any of these early kings had died.

A kingdom overshadowed
These sultans reigned through the collapse of the Malay world's old
order. Sultan Mahmud Shah of Malacca, from whom an earlier Kedah
prince had once sought the royal regalia as a mark of Malacca's own
seniority among Malay courts, was driven from his capital by the
Portuguese conquest of 1511 and died in exile two years later.
Malacca's fall left no single Malay power in a position to protect a
smaller court like Kedah's, and by the time a Portuguese account of
1516 described the kingdom, it named Kedah plainly as tributary to
Siam - overshadowed, as it would remain for the following century,
by stronger neighbors on every side.
Blockaded for its tin
expansionDrafted from Winstedt, History of Kedah (1920)
Kedah's standing as a major tin port made it a target for every
power with a fleet nearby. In 1611 a Portuguese force sailing down
from Tenasserim under Dioge de Mendoca Furtado destroyed the towns
of Kedah "with fire and sword."
Nominal Siamese overlordship did
nothing to prevent the attack, nor did it prevent Aceh's Sultan
Iskandar Muda, campaigning along the peninsula in 1619, from leading
Kedah's own Sultan Sulaiman Shah into captivity alongside the ruler
of Perak - an occupation of Achinese influence that lingered for
years afterward.

A river kept under blockade
The Dutch East India Company proved just as persistent a problem.
In 1642 the reigning king agreed to let the Company have half of
Kedah's tin production at a fixed price and to admit no ship without
its permission - a concession Perak, protected by its own vassalage
to Aceh, had refused to make. When Kedah chafed at the arrangement,
the Company responded with force: instructions from Batavia ordered
the blockade of the Kedah river repeatedly through the 1660s, and
the correspondence of the Dutch governors shows the order renewed
again and again against a kingdom that, for all its wealth in tin
and gold and elephants, could not shake off the Company's grip on
its own coastline.
By the early eighteenth century Kedah was
recorded as one of several ports formally subordinate to the Dutch
government at Malacca.

A population cut to a thirtieth
endDrafted from Winstedt, History of Kedah (1920)
Portuguese raids, an Achinese captivity, and decades of Dutch
blockade had all failed to break Kedah outright. The Siamese
invasion of 1821 did what none of them had managed. Sultan Ahmad
Tajuddin Halim Shah, who had begun his reign at Kuala Kedah, was
forced to flee to Province Wellesley as Siamese forces occupied the
country and divided it into four separately administered parts -
Kedah proper, Setul, Perlis and Kubang Pasu, each placed under its
own ruler answering to Siam.
Six years, a thirtieth of a population
The scale of the devastation that followed is recorded starkly: in
six years, Kedah's population fell from 180,000 to 6,000. The exiled
sultan spent years trying to recover his throne, at one point
sailing from Malacca toward Kedah to launch an attack, only to be
intercepted and taken to Penang by a British gunboat before he could
land. Not until 1843 was he permitted to return, restored to a
diminished Kedah under continuing Siamese protection, reigning from
Kota Kuala Muda because Alor Star, the old capital, had grown over
with forest in his absence.

An afterword under two protectors
Kubang Pasu was eventually restored to Kedah's own governance, but
Perlis remained a separate state and Setul stayed part of Siamese
territory permanently. The arrangement held until 1909, when Siam
transferred its suzerainty over Kedah to Great Britain, which
administered it thereafter as one of the Unfederated Malay States -
a second protector following the first, neither of them the
independent sultanate that had once bargained with the Dutch East
India Company on something closer to equal terms.
