The Kilwa Sultanate was a Medieval sultanate, centered at Kilwa (an island off modern-day Tanzania), 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. It was replaced by the Arab family of Abu Moaheb until 1505, when it was 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.
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 (Strong, 1895), 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 (Ethiopian) 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 (and 12th ruler of Kilwa, c. 1178-1195), 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 (plus numerous smaller places) - 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 (then known by its Arabic name of Island of the Moon). To the north, Kilwa's power was checked by the independent Somali city-states of Barawa (a self-ruling aristocratic republic) and Mogadishu (the once-dominant city, Kilwa's main rival). 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 (e.g. outposts like Mozambique Island) 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 (literally, 'coast-dwellers'). Nonetheless, the Muslims of Kilwa (whatever their ethnicity) would often refer to themselves generally as Shirazi or Arabs, and to the unconverted Bantu peoples of the mainland as Zanj or Khaffirs ('infidels').
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 (principally millet and rice), meats (cattle, poultry) 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 (cloth, etc.) from Arabia and India, which were then swapped in the highland market towns for Bantu-produced agricultural commodities (grain, meats) for their own subsistence and precious raw materials (gold, ivory, etc.) 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 (viziers and emirs), who played the roles of kingmakers, and de facto rulers, and occasionally tried to foist themselves (or one of their family members) 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 (son of an earlier vizier). 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 (known as Mir Habrahemo in Barros, Abraemo in Goes), 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 (ibn Muhammad?) 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 (belatedly) 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 (known to the Portuguese as Muhammad Arcone), certainly advised Emir Ibrahim to strike up an alliance with the Portuguese (and for his pains, was given up as a hostage to the Portuguese by the Emir, who then refused ransom him back - allowing him to be subjected to Gama's wrath.)
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 (largely to be directed against Mombassa). After Emir Ibrahim's coup, it was certainly not hard to persuade the ruling sheikh Isuf of Sofala (Yçuf in Barros, Çufe in Goes) (apparently a nephew of the late Emir Muhammad) 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 (Fort Santiago) 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 (a relative of Emir Ibrahim). 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 (& Emir Ibrahim) seized control of much of the city, driving sultan Hussein (and the partisans of Arcone) 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.
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 (or for) sheikh Moheddin (Majid?) 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.

- 32. (1442) Ismail ibn Hussein (uncle of previous) - ruled 14 years. Challenged by pretender Sa'id ibn Hassan, who secured the support of Hassan ibn Abu Bakr, ruler of Zanzibar. The Zanzibaris assembled a coalition to seize Kilwa by force. But Ismail's ministers, vizier Suleiman and Emir Muhammad managed to bribe the key organizer of the expedition, who withdrew the Zanzibari troops and left pretender Sa'id stranded on the beach of Kilwa with only a small body of attendants. Although pardoned by Ismail, Sa'id went into hiding.
- 33. (1454) vizier Suleiman (vizier of previous) At death of sultan Ismail, in the first known usurpation by ministers, the vizier Suleiman and Emir Muhammad al-Mazlum launched a coup and seized power together, with Suleiman declaring himself Sultan. However, popular opinion was strongly against the vizier, so he decided to pass the throne over to the more popular Emir Muhammad.
- 34. (1454) Muhammad ibn al-Hussein ibn Muhammad ibn Suleiman al-Mazlum ('Emir Muhammad', noble co-conspirator with previous) According to Zanzibar chronicle, after the death of vizier Suleiman, Muhammad appointed the old pretender Sa'id ibn Hassan to the post as his own vizier. Muhammad died shortly after. Reigned for less than a year.(deposed, according to Barros).
- 35 (1455) Ahmad ibn Suleiman (son of the late vizier?), deposed within a year by partisans of the old royal family. (Barros omits Ahmad, says the partisans deposed Muhammad directly).
- 36 (1456) al-Hassan ibn Ismail (son of 32nd sultan Ismail), installed by coup. Ruled ten years.
- 37. (1466) Sa'id ibn al-Hassan/Hussein (son of previous, according to Barros; same old pretender (cf.32nd) according to Zanzibar chronicle) - ruled 10 years, Upon his death, the Kilwa Sultanate fell into disarray. There was another ministerial coup d'état.
- 38. (1476) Suleiman ibn Muhammad ibn al-Husayn ('Vizier Suleiman') vizier seized throne after death of Sa'id, declared himself sultan and elevated his own brother, Muhammad Kiwabi, to the dignity of emir. But vizier-turned-sultan Suleiman's rule lasted little over a year.
- 39. (1477) Abdullah ibn al-Hassan (brother of 37th sultan Sa'id) elevated by people of Kilwa against usurping vizier Suleiman. Ruled one and half years.
- 40. (1478) Ali ibn Hassan (brother of previous). Ruled 1.5 years. Upon his death, Emir Muhammad Kiwabi (brother of the late vizier Suleiman) seized power, and installed his nephew al-Hassan as sultan.
- 41 (1479) al-Hassan ibn Suleiman (son of vizier Suleiman), first time, installed by his uncle, Emir Muhammad. But al-Hassan proved an unpopular sultan and was deposed by his own uncle after 6 years.
- 42. (1485) Sabhat ibn Muhammad ibn Suleiman ('Xumbo', a scion of royal lineage, son of 31st sultan, al-Adil) installed by Emir Muhammad, after popular opposition to his first choice al-Hassan. Ruled one year, then died. According to Zanzibar chronicle, Emir Muhammad tried to install his nephew al-Hassan again.
- 43. (1486) al-Hassan ibn Suleiman (second time) installed by uncle Emir Muhammad once again, but popular opposition proved too strong. Emir Muhammad decided to depose al-Hassan once again and look for a suitable sultan from the royal dynasty.
- 44. (1490) Ibrahim ibn Muhammad (brother of Sabhat, another son of al-Adil) installed by Emir Muhammad to replace his nephew al-Hassan. But the deposed al-Hassan ibn Suleiman launched a coup attempt to depose Ibrahim, that resulted in quite some bloodshed. In the end, al-Hassan's ambitions were foiled by his uncle Emir Muhammad, who, seeking to restore order, declared unambiguously that Ibrahim, a descendant of kings, had precedence over al-Hassan, who was only of a family of viziers. al-Hassan driven into exile on the mainland. Ibrahim ruled for two years, until Emir Muhammad decided to depose him himself.
- 45. (1495) Muhammad ibn Kiwab ('Emir Muhammad Kiwabi', the powerful emir) declared himself sultan, only very briefly, probably just to show he can or to satisfy his curiosity or perhaps just to forestall a renewed bid by his exiled nephew al-Hassan while he sorted through other candidates. In any case, Muhammad abdicated soon after, and installed another royal family member, al-Fudail.
- 46. (1495) al-Fudail ibn Suleiman ('Alfudail', nephew of Ibrahim, thus of royal blood) installed by Emir Muhammad, after his own abdication. This is 1495 AD (901 AH). Immediately after ascension, exiled ex-ruler Hassan ibn Suleiman returned with a mixed army of Bantus and Kilwan exiles to reclaim the throne. The sheikh of Zanzibar offered to mediate, and, through his good offices, al-Fudail even contemplated ceding the throne to Hassan and ending the quarrel. But Emir Muhammad refused to allow it. Instead, he promised al-Hassan an amnesty, but only if he returned to private life in Kilwa. While awaiting Hassan's reply to this offer, the great Emir Muhammad Kiwabi died rather suddenly. In the confusion, pretender Hassan infiltrated troops into Kilwa city, under the command of his own son Sa'id. Caught by city authorities, Sa'id invented a story about just 'preparing the house' for his father's peaceful return to Kilwa as a private citizen. To allay suspicions, Sa'id finally proposed to lead a Kilwan embassy, escorted by a squad of city troops, to his father's encampment to confirm his story. Thinking the crisis had been defused, at least until the embassy returned from its investigation, Kilwa let its guard down. But the embassy did not return. Rather, Sa'id led it to at trap, and it was massacred. The army of al-Hassan attacked that very same night. The surprised city rallied frantically to its defenses, and a great and bloody battle ensued outside the gates of the city. The Kilwans defeated al-Hassan and put an end to the perennial pretender. The victorious Sultan al-Fudail appointed a certain Ibrahim ibn Suleiman as emir, to replace the late Emir Muhammad. But this state of affairs only lasted a few years.
End of Mahdali dynasty c. 1495, beginning of a series of usurpers and Portuguese puppets.
- 47. (1499) Ibrahim ibn Suleiman ('Emir Ibrahim', 'Mir Habraemo' in Portuguese) minister of Sultan al-Fudail; deposed and murdered the sultan and took power himself not as sultan, but in the name of an absent son of an earlier sultan Suleiman. Incensed, the regional vassals of the Kilwan Sultanate refuse to recognize the usurpation. Emir Ibrahim will be driven out and deposed by the Portuguese captain Francisco de Almeida in 1505.
- 48. (1505) Muhammad ibn Rukn ad Din (Muhammad 'Arcone' to the Portuguese, Kilwan noble, not of royal lineage) installed by Francisco de Almeida as Portuguese vassal sultan of Kilwa. But remembering the importance of constitutional propriety, Muhammad immediately appointed royal prince Muntari, the son of late al-Fudail, as his successor. He was assassinated after a year.
- 49 (1506) Micante

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 (unearthed during an excavation in Oman). 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. (See Janszoon voyage of 1605-6 and History of Australia (1606–1787).) 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.

Following Barros (1552: p.227-28)'s more precise dating, assuming 996 to be correct for Ali ibn Bashat, then the dates of his successors are 1001 (Dawud ibn Ali), 1005 (Khalid ibn Bakr), 1007 (al-Hassan ibn Suleiman), 1023 (Ali ibn Dawud I), 1083 (Ali ibn Dawud II), 1089 (al-Hassan ibn Dawud), 1113 (Suleiman) after which Barros becomes unclear again.
- Changa is the name given by the chronicles for a mainland Bantu kingdom that repeatedly harassed the early Kilwa colony. It is a possible reference to the local 'Changamire' dynasty that, in the 15th century, began to challenge the overlordship of the Monomatapa and would go on to overthrow it and establish the Rozwi confederacy. The Changamire is not known to have existed at the time the chronicles suggest, but they were beginning to emerge at the time the chronicle was written down, and so may be a reference to their ancestors.
- Dating unclear. Not being Shirazi, Khalid ibn Bakr is not in Bosworth's (1996) list. But he is given in Zanzibar Chronicle (Strong, 1895: p.389) and Barros (1552: 226).
- Zanzibar Chronicle (Strong 1895: p.389) claims al-Hassan fled to Zanzibar following a second invasion by the Changa, who installed a usurping emir Muhammad ibn al-Hussein al-Mundhiri. But the usurper was quickly toppled in a popular rising, and the exiled sultan al-Hassan was restored. Dates are problematic. Barros (1552: p.226) claims al-Hassan ruled sixteen years and was succeeded by his nephew Ali ibn Dawud, who ruled sixty. But Bosworth (1996) identifies Ali as only ascending around 1042, leaving the intervening gap unaccounted for.

- Barros (1552: p.227) identifies Suleiman ibn al-Hassan as the son of Dawud ibn Suleiman, inheriting his enterprises in Sofala, which he used as a launchpad to become lord of Sofala and master of the Swahili coast.
- "que foi mui excellente Cavalleiro" (Barros, 1552: p.228)
- Zanzibar chronicle (Strong, 1895: p.390) claims Dawud ruled for only a few days and was deposed by his uncle. Probably confusing this ith his son, Suleiman.
- Zanzibar chronicle (Strong 1895: p.390) cites Talut ibn Dawud as Talut ibn Hussein, suggesting he was a son rather than nephew of previous. Also says he died while on pilgrimage to Mecca, and was succeeded by either his son or brother.
- Known as Muhammad Ladil to Barros; Zanzibar chronicle names him as 'al-Malik al-Adil', and gives his real name as Muhammad ibn Suleiman ibn al-Hussein, claiming he had served as vizier, and was elevated to the throne by the nobles and people. Also claims he ruled 22, rather 9 years.
- Zanzibar chronicle reports it was his nephew Hajj Rush (son of earlier sultan Hussein) that rebuilt the mosque of Kilwa, adamant about doing so with his own money and resources. Nonetheless, his uncle sultan Suleiman insisted on donating one thousand pieces of gold to the effort; Hajj Rush accepted the donation reluctantly, but secretly put the money aside, and returned the donation to Suleiman's heirs after the sultan's died.
- Barros suggests Ibrahim was the son of Emir Muhammad, and thus of the vizier family. The Zanzibar chronicle insists he was a brother of Sabhat, and thus of royal lineage (son of 31st sultan Muhammad al-Adil). Our list opts for the latter.
