An island sultanate at the head of the Lamu archipelago, ruling a mainland coast from the Juba to Kilifi at its widest, that spent a rebellious generation playing Oman and its Mazaru'i neighbours in Mombasa against each other before a dead sultan's own succession dispute finished it.

Pate breaks with OmanRevolt
In the same year Mombasa's Mazaru'i made themselves independent of the Imam, Pate withdrew its own allegiance to Oman - and soon afterward went to open war with the Mazaru'i themselves over the division of Pemba's tax revenue, besieging their position at Kilindini before the two sides came to terms.

Pate recognises the Imam's ruleTreaty
Thirty years after breaking with Oman, Pate agreed to recognise the Imam's rule - a diplomatic accommodation rather than a surrender, since no garrison, tribute or governor from Oman followed it, and Pate's own sultans went on ruling exactly as before.

Sultan Fumomadi's death divides the throneSuccession crisis
Fumomadi's death opened a contested succession between Fumoluti, favoured by a party in Lamu, and Ahmed; Mombasa's Mazaru'i governor marched troops to Pate, installed Ahmed on the throne, and carried Fumoluti off to Mombasa, driving his partisans into exile in Lamu and setting the Mazaru'i against that town when they attacked it there and were repulsed.

Sa'id's fleet takes Pate, Siu and FazaBattle
Ordered to expel the Mazaru'i garrison the Mombasa succession crisis had left behind and refusing, Pate was taken outright by a fleet under Sa'id's general Hamad, along with the dependent towns of Siu and Faza - the end of Pate ruling itself under a sultan of its own line.

Shaking off Oman
formationDrafted from Stigand, The Land of Zinj, Being an Account of British East Africa, Its Ancient History and Present Inhabitants (1913)
By the time the Imam of Oman first began installing garrisons on the
Swahili coast, Pate was already the kind of sultanate that measured
its reach in dependencies rather than in the walls of a single town.
Under Sultan Fumo Bakari, whose father Bwana Tamu had ruled with the
Imam's own favour, Pate counted among its possessions Lamu, Manda,
Pemba, and the mainland coast running from the Juba river all the way
south to Kilifi - a stretch of the coast longer than the distance
between Mombasa and Zanzibar.

That reach did not survive contact with an Omani garrison next door
for long. In 1739 the Imam placed a clan of Omani settlers, the
Mazaru'i, in the fort at Mombasa as his own custodians, and within a
few years Mombasa's custodians had made themselves independent rulers
in their own right. Pate followed the same course in 1746, the very
year the Mazaru'i governor Ali bin Osman declared himself free of the
Imam: it withdrew its own allegiance to Oman and went on governing its
dependencies exactly as before.
A quarrel over Pemba's taxes
Independence from Oman did not mean peace with Mombasa. Pemba Island,
claimed by both, produced a tax revenue neither side was willing to
share evenly, and the dispute broke into open war: Pate seized
Kilindini and besieged the Mazaru'i position there before the two
sides worked out an understanding and Pate withdrew. Nothing was
settled permanently by the fighting - Pemba's revenue remained
contested for decades afterward - but Pate had shown, within months of
breaking from Oman, that it intended to hold its own claims against
its nearest and most dangerous neighbour as readily as against the
Imam who had lost it.
A governor ejected
expansionDrafted from Stigand, The Land of Zinj, Being an Account of British East Africa, Its Ancient History and Present Inhabitants (1913)
Pate did not confine its ambitions to squabbling with Mombasa over
Pemba. It sent its own expedition north to Barawa to press old claims
on the Juba river - the same stretch of coast its sultans had counted
as a dependency since Fumo Bakari's day - asserting a reach of its own
even while its southern quarrel with the Mazaru'i sat unresolved.
That assertiveness cost it, before long, at home. Internal troubles
broke out within Pate itself, and the Mazaru'i, watching from
Mombasa, saw their opening. They landed an expedition on the island
and forced Pate to accept a governor of their own choosing - a
direct Mazaru'i hand on Pate's own throne, the closest either side had
come to actually ruling the other rather than merely raiding it. It
did not last. The governor was ejected in his turn, and Pate returned
to governing itself.
A recognition that cost nothing
By 1776 the two neighbours had settled into something less costly
than continuous war. Pate agreed that year to recognise the Imam of
Oman's rule - the same Imam whose authority it had rejected thirty
years before - but the recognition arrived without a garrison, without
tribute and without a governor to enforce it. Pate's own sultans went
on ruling precisely as they had while independent; what had changed
was only that Oman now had, on paper, a claim it could point to
whenever it next found the coast worth the trouble of enforcing.
A throne decided in Mombasa
contractionDrafted from Stigand, The Land of Zinj, Being an Account of British East Africa, Its Ancient History and Present Inhabitants (1913)
Sultan Fumomadi's death in 1807 opened the succession Pate could least
afford: a divided one, at the exact moment its most powerful neighbour
still had a governor and an army within reach of the island. Fumoluti
was the candidate a party in Lamu favoured; Ahmed was the candidate
Mombasa's Mazaru'i governor favoured, and the Mazaru'i did not wait to
see which side would win on its own. They marched troops to Pate,
installed Ahmed on the throne themselves, and carried Fumoluti off to
Mombasa as a captive rather than a rival - not exile at a safe
distance, but removal to the one place his enemies could watch him
indefinitely.
Fumoluti's own partisans read the outcome correctly and did not wait
for a second round. They emigrated to Lamu rather than accept a throne
settled by Mazaru'i soldiers, swelling a faction there that Mombasa
now had every reason to distrust. When the Mazaru'i followed up with
an attack on Lamu itself, hoping to finish what installing Ahmed had
started, they were repulsed - the first clear check to Mombasa's
interference in Pate's own succession, and proof that the crisis of
1807 had not, in fact, settled anything at all.
A throne, but not a free hand
Ahmed reigned afterward as Pate's sultan, but the manner of his
installation was itself the damage. A ruler placed on the throne by a
foreign garrison's soldiers, over a rival that same garrison had
personally carried off, governed with Mombasa's fingerprints on the
succession whether he intended to or not. Pate had broken from Oman in
1746 precisely to rule itself; sixty-one years later, it was Mazaru'i
troops from the very neighbour it had once gone to war with over
Pemba who decided who would sit on its throne.
Siu and Faza taken too

Lamu drew its own lesson from surviving the Mazaru'i attack the 1807
succession crisis had provoked: that it could not count on surviving
a second one alone. It appealed directly to Imam Sa'id for protection,
and in 1811 Sa'id answered by sending a governor of his own to Lamu
and building a fort there - an Omani foothold planted in Pate's own
archipelago, a few days' sail from the island whose throne the
Mazaru'i had so recently filled by force.

Pate, still carrying whatever Mazaru'i garrison had been left behind
from Ahmed's installation, was now caught between two powers rather
than one. In 1822 Sa'id ordered the Mazaru'i garrison withdrawn from
Pate outright. Pate refused. Sa'id answered with a fleet under his
general Hamad, which took Pate, and with it the dependent towns of
Siu and Faza, by force.
The end of ruling itself
Nothing in the source describes a battle of any length, a siege, or
resistance that came close to matching what Mombasa itself would put
up against the same Sa'id six years later. Pate simply fell, along
with the towns that had once been counted among its own dependencies
in Fumo Bakari's day. The sultanate that had broken from Oman in 1746
to govern the Juba-to-Kilifi coast on its own terms ended, seventy-six
years later, ruled from Zanzibar rather than from Pate - one more
piece of the same coastal network that Sa'id, within Pate's own
lifetime as an independent state, had already begun assembling from
Mombasa to Lamu.
Ordered to give up the Mazaru'i garrison its own 1807 succession crisis had left behind and refusing, Pate was taken by a fleet under Sa'id's general Hamad, along with the dependent towns of Siu and Faza - fifteen years before Sa'id took Mombasa itself by the same kind of pressure.
