Kilwa Sultanate


The Kilwa Sultanate was a Medieval sultanate, centered at Kilwa, whose authority, at its height, stretched over the entire length of the Swahili Coast. According to the legend, it was founded in the 10th century by Ali ibn al-Hassan Shirazi, a Persian prince of Shiraz. His family ruled the Sultanate until the year 1277. They were replaced by the Arab family of Abu Moaheb until 1505, when they were overthrown by a Portuguese invasion. By 1513, the sultanate was already fragmented into smaller states, many of which became protectorates of the Sultanate of Oman.

History

The story of Kilwa begins around 960-1000 AD. According to legend, Ali ibn al-Hassan Shirazi was one of seven sons of a ruler of Shiraz, Persia, his mother an Abyssinian slave. Upon his father's death, Ali was driven out of his inheritance by his brothers. Setting sail out of Hormuz, Ali ibn al-Hassan, his household and a small group of followers first made their way to Mogadishu, the main commercial city of the East African coast. However, Ali failed to get along with the city's Somali elite and he was soon driven out of that city as well.
Steering down the African coast, Ali is said to have purchased the island of Kilwa from the local Bantu inhabitants. According to one chronicle, Kilwa was originally owned by a mainland Bantu king 'Almuli' and connected by a small land bridge to the mainland that appeared in low tide. The king agreed to sell it to Ali ibn al-Hassan for as much colored cloth as could cover the circumference of the island. But when the king later changed his mind, and tried to take it back, the Persians had dug up the land bridge, and Kilwa was now an island.
Rather than being a literal retelling of events, this legendary history serves to legitimize the dynasty through ties to Islam. According to Horton and Middleman, "the descent from a noble Islamic family and an Abyssinian slave 'explains' why the rulers were both black but also with royal Muslim descent; the giving of cloth to the ruler made him 'civilized' and so his daughter became marriageable."
Kilwa's fortuitous position made it a much better East African trade center than Mogadishu. It quickly began to attract many merchants and immigrants from further north, including Persia and Arabia. In just a few years, the city was big enough to establish a satellite settlement at nearby Mafia Island.
Kilwa's emergence as a commercial center challenged the dominance once held by Mogadishu over the East African coast. Suleiman Hassan, the ninth successor of Ali, wrested control of the southerly city of Sofala. Wealthy Sofala was the principal entrepot for the gold and ivory trade with Great Zimbabwe and Monomatapa in the interior. The acquisition of Sofala brought a windfall of gold revenues to the Kilwa Sultans, which allowed them to finance their expansion and extend their powers all along the East African coast.
At the zenith of its power in the 15th century, the Kilwa Sultanate owned or claimed overlordship over the mainland cities of Malindi, Inhambane and Sofala and the island-states of Mombassa, Pemba, Zanzibar, Mafia, Comoro and Mozambique - essentially what is now often referred to as the "Swahili Coast".
Kilwa also claimed lordship across the channel over the myriad of small trading posts scattered on the coast of Madagascar. To the north, Kilwa's power was checked by the independent Somali city-states of Barawa and Mogadishu. To the south, Kilwa's reach extended as far as Cape Correntes, below which merchant ships did not usually dare sail.
While a single figure, the Sultan of Kilwa, stood at the top of the hierarchy, the Kilwa Sultanate was not a centralized state. It was more a confederation of commercial cities, each with its own internal elite, merchant communities and trade connections. The Sultan might appoint a governor or overseer, but even his authority was not consistent - in some places he was a true governor in the Sultan's name, whereas in more established cities like Sofala his powers were much more limited, more akin to an ambassador to the city, than its governor.

Society and economy

Despite its origin as a Persian colony, extensive inter-marriage and conversion of local Bantu inhabitants and later Arab immigration turned the Kilwa Sultanate into a veritable melting pot, ethnically indifferentiable from the mainland. The mixture of Perso-Arab and Bantu cultures is credited for creating a distinctive East African culture and language known today as Swahili. Nonetheless, the Muslims of Kilwa would often refer to themselves generally as Shirazi or Arabs, and to the unconverted Bantu peoples of the mainland as Zanj or Khaffirs.
The Kilwa Sultanate was almost wholly dependent on external commerce. Effectively, it was a confederation of urban settlements, and there was little or no agriculture carried on within the boundaries of the sultanate. Grains, meats and other necessary supplies to feed the large city populations had to be purchased from the Bantu peoples of the interior. Kilwan traders from the coast encouraged the development of market towns in the Bantu-dominated highlands of what are now Kenya, Tanzania, Mozambique and Zimbabwe. The Kilwan mode of living was as middlemen traders, importing manufactured goods from Arabia and India, which were then swapped in the highland market towns for Bantu-produced agricultural commodities for their own subsistence and precious raw materials which they would export back to Asia.
The exception was the coconut palm tree. Grown all along the coast, the coconut palm was the mainstay of Kilwan life in every way - not only for the fruit, but also for timber, thatching and weaving. Kilwan merchant ships - from the large lateen-rigged dhows that plied the open oceans to the small zambucs used for local transit - were usually built from the split trunks of coconut palm wood, their sails made from coconut leaf matting and the ships held together by coconut coir.
The Kilwa Sultanate conducted extensive trade with Arabia, Persia, and across the Indian Ocean, to India itself. Kilwan ships made use of the seasonal monsoon winds to sail across to India in the summer, and back to Africa in the winter. Kilwan pilots had a reputation for extraordinary sailing accuracy. The Portuguese marveled at their navigational instruments, particularly their latitude staves, which they considered superior to their own.
Nonetheless, the coir-sewn Kilwan ships were not seaworthy enough to brave the treacherous waters and unpredictable violent gusts around Cape Correntes, so the entire region south of that point was rarely sailed by Kilwan merchants. Inhambane was the most southerly settlement that can be considered part of the Kilwan trading empire.

Decline and fall

In its later years, the Sultans of Kilwa began falling into the hands of their ambitious ministers, who played the roles of kingmakers, and de facto rulers, and occasionally tried to foist themselves on the throne, in competition with the royal dynasty. The most successful was probably Emir Muhammad Kiwabi, who ruled Kilwa for nearly two decades through several sultans, including himself at one point.
Throughout his long 'reign', Emir Muhammad fought an on-again and off-again battle with his nephew, Hassan ibn Suleiman. Muhammad had, in fact, tried to install Hassan as sultan a couple of times, but it met tremendous resistance from the population of Kilwa. Eventually, Emir Muhammad decided that, in the interests of constitutional propriety and civic peace, Kilwa sultans should always come from the royal dynasty, not families of viziers. Muhammad held that line more-or-less down to the end, thwarting Hassan's ambitions.
The last sultan installed by Emir Muhammad before his death was the royal prince al-Fudail ibn Suleiman in 1495. The man who succeeded to Muhammad's post, Emir Ibrahim, helped al-Fudail crush the ambitious Hassan once and for all in a great battle outside Kilwa. But it was not long after this battle that Emir Ibrahim is said to have betrayed and murdered sultan al-Fudail. Rather than declare himself sultan, Ibrahim took power merely with the title of emir, and claimed to be exercising rule in the name of a son of an earlier sultan Suleiman of the old royal dynasty. That no one had seen or heard of this absent prince for years was quite convenient for Emir Ibrahim.
Emir Ibrahim's usurpation was met with shock not only in Kilwa, but in the vassal cities as well. Emir Muhammad had recognized the importance of constitutional propriety for peace in the Kilwa Sultanate. Emir Ibrahim's murderous coup had run roughshod over it. Most of the local governors of the Kilwa vassal cities, many who were either relatives or had owed their positions to Emir Muhammad and the royal dynasty, refused to acknowledge the usurpation of Emir Ibrahim, and began charting an independent course for their own city-states. The writ of Emir Ibrahim probably only covered the city of Kilwa itself and possibly Mozambique Island.
This was more or less the condition of the Kilwa Sultanate when the Portuguese arrived.
Portuguese scout Pêro da Covilhã, disguised as an Arab merchant, had travelled the length of the Kilwa Sultanate in 1489-90, and visited the ports of Malindi, Kilwa and Sofala, and delivered his scouting report back to Lisbon, describing the condition of the Kilwa Sultanate in quite some detail. The first Portuguese ships, under Vasco da Gama, on their way to India, reached the sultanate in 1497. Gama made contact with the Kilwa vassals of Mozambique, Mombassa and Malindi, seeking to secure their cooperation as staging posts for the Portuguese India Armadas.
In 1500, the 2nd Portuguese India Armada, under Pedro Álvares Cabral, visited Kilwa itself, and attempted to negotiate a commercial and alliance treaty with Emir Ibrahim. But emir prevaricated and no agreement was reached.
The well-armed Fourth Armada of 1502, under Vasco da Gama again, came in a more mean-spirited mood, indisposed to take no for an answer. Having secured separate treaties with Malindi, Mozambique and all-important Sofala, the Portuguese brought their menacing fleet to bear on Kilwa itself, and extorted a sizeable tribute from emir Ibrahim.
Some have speculated whether Emir Ibrahim missed a golden opportunity to restore his fortunes, that had a treaty with Cabral been reached back in 1500, he might have secured the assistance of the Portuguese navy in bringing the half-independent vassals back under his sway. At least one Kilwan nobleman, a certain Muhammad ibn Rukn ad Din, certainly advised Emir Ibrahim to strike up an alliance with the Portuguese
As it turns out, the vassals used the Portuguese, one by one, to secure their permanent break from the Sultanate. The ruler of Malindi was the first to embrace the Portuguese, forging an alliance in 1497. After Emir Ibrahim's coup, it was certainly not hard to persuade the ruling sheikh Isuf of Sofala to break away. He signed a treaty with the Portuguese in 1502, and followed it up by allowing the construction of a Portuguese factory and fort in Sofala in 1505.
It was in 1505 that Francisco de Almeida brought his fleet into the harbor of Kilwa, and landed some 500 Portuguese soldiers to drive Emir Ibrahim out of the city. Almeida installed the aforementioned Muhammad Arcone on the throne, as a Portuguese vassal. Remembering constitutional proprieties, Arcone insisted that Micante, the son of the late sultan al-Fudail be his designated successor. The Portuguese erected a fortress on Kilwa and left a garrison behind, under the command of Pedro Ferreira Fogaça to keep an eye on things.
Portuguese rule was not very welcome. Particularly grating was the imposition of Portuguese Mercantilist laws on the sultanate, forbidding all but Portuguese ships to carry trade to the principal coastal towns - essentially putting many leading Kilwan merchants out of business.
The Portuguese did not stay very long. In May, 1506, Muhammad Arcone was lured and assassinated by the sheikh of Tirendicunde. As per the pre-arranged succession rule, Micante ascended to the throne. But Fogaça, seeing that Micante's ascension was supported by the old faction of Emir Ibrahim, concluded he would not do as a Portuguese puppet. Consequently, he deposed Micante and installed Hussein ibn Muhammad, a son of Arcone, as the new sultan.
Chaos broke out in the city of Kilwa. Partisans of Micante seized control of much of the city, driving sultan Hussein to seek refuge by the Portuguese Fort Santiago. Street fighting and soon fires broke out. In the chaos, streams of Kilwan residents fled the city, leaving it practically deserted, save for a handful of roving partisan gangs and the terrified Portuguese garrison.
Hearing of the Kilwan chaos all the way in India, the Portuguese vice-roy Almeida dispatched a magistrate Nuno Vaz Pereira, to inquire into the matter. Arriving in late 1506, Pereira convened the competing sultans Micante and Hussein, and asked them present their cases. Pereira ruled in favor of Hussein, confirming him as sultan, but softened the blow by relieving the unpopular commander Fogaça and lifting the mercantilist restrictions on Kilwa shipping.
The Kilwan refugees returned and a modicum of peace resumed, but only briefly. For Hussein put it in his head to lead the Kilwan army against Tirendicunde, to avenge his father's murder. The town was brutally sacked, and numerous prisoners taken. Hussein then dispatched emissaries to all the vassal cities of the Kilwa Sultanate, ordering them to return to obedience, or else meet the same fate.
Fearing that Hussein's spate of tyranny might jeopardize Portuguese interests in East Africa, viceroy Almeida reversed Pereira's decision, deposed Hussein and reinstated Micante.

Rulers

The chronology of rulers of the Kilwa Sultanate is reported in a chronicle translated into Portuguese in the 16th century, and recorded by the chronicler João de Barros. There is another surviving chronicle by an unknown author, written in the early 16th century, and compiled in 1862 by sheikh Moheddin of Zanzibar. The Barros and Zanzibar chronicles are not always in concordance with each other. The following follows Barros in its outlines, but fills in details from the Zanzibar chronicle. Alternate spellings and nicknames, mainly given in Barros's chronicle, are in italics. Dates are approximate years of ascension.

Shirazi era

End of Persian Shirazi dynasty c. 1277, beginning of Mahdali dynasty of Yemeni Arab sayyids, or what the Zanzibar chronicle calls the "family of Abu al-Mawahib".

Mahdali era

End of Mahdali dynasty c. 1495, beginning of a series of usurpers and Portuguese puppets.

Portuguese era

In 1944, a small number of copper coins with Arabic inscriptions were discovered on a beach in Jensen Bay on Marchinbar Island, part of the Wessel Islands of the Northern Territory of Australia. These coins were later identified as from the Sultanate of Kilwa. Only one such coin had ever previously been found outside east Africa. The inscriptions on the Jensen Bay coins identify a ruling Sultan of Kilwa from the 12th century. This discovery has been of interest to those historians and archaeologists who believe it likely that people made landfall in Australia or its offshore islands before the first generally accepted such discovery, by the Dutch sailor Willem Janszoon in 1606. A group called the Past Masters, a network of academics, practitioners and enthusiasts is investigating the Wessel Islands for more clues. A further five coins had been found on Marchinbar Island in 1945 by RAAF radar operator Morry Isenberg. In 2018 another coin, also thought to be from Kilwa, was found on a beach on Elcho Island, another of the Wessel Islands by archaeologist and member of the Past Masters, Mike Hermes.
