Muhammad Kisoki and Borno

            The altercation between Borno and Kano during the reign of the latter’s Muhammad Kisoki is an intriguing example of conflict between the two states. Although there are some chronological ambiguities that require attention, Yusufu Bala Usman has connected Kisoki’s raid on Nguru with the Kano campaign of Borno during the time of Idris Alooma. According to Ahmad b. Furtu, a highly biased but contemporary source, Kano had “betrayed” Borno through fortifying towns or sites on their border with Borno and launching attacks. In response, Borno raised an army which destroyed the fortifications or walls and then failed to take Kano itself.[1] Importantly, the opposing side’s perspective can be glimpsed through the Kano Chronicle. Thus, one does not have to rely solely or mainly on Ahmad b. Furtu’s panegyrical text for his patron, unlike the case of most of the other peoples Borno went to war against during the lengthy reign of Idris Alooma. Therefore, this brief article shall examine Borno-Kano relations during the reign of Muhammad Kisoki, focusing on the raids launched from Kano against Borno and the response. This post argues that Muhammad Kisoki’s eastern raids likely correspond to the campaigns described by Ahmad b. Furtu and were autonomous Kano initiatives rather than part of a Kebbi-led regional conflict.

By examining this episode more closely, however, one sees yet again the influence of Maidaki Hauwa (and her brother, Guli) in a confrontation with Borno. Maidaki Hauwa had previously been involved with suppressing a revolt by the Dagachi in Kano, someone descended from the Sayfawa line and very influential. After preventing his rebellion, her son, Abdullahi, returned from a campaign and then faced an invasion from Borno. Undoubtedly linked to the Dagachi’s actions, Kano’s king, accompanied by mallams, had to submit to the mai. Then, once the mai returned to Borno, Abdullahi tricked or deceived the Dagachi and gave his office to a slave.[2] Although taking place several years before the Borno-Kano conflict during Idris Alooma’s reign (1564-1596, according to Lange’s chronology), it is very likely that Kisoki’s influential grandmother and her brother, whose influence at court was extremely powerful, shaped Kano state policy with regard to the frontier with Borno. By taking another look at this critical juncture, one can see just how realpolitik shaped relations between a regional power like Borno and the smaller Hausa states which, depending on one’s view, paid tribute or sent regular “gifts” to the mai.

But can we confidently date Muhammad Kisoki’s attacks on Borno with the reign of Idris Alooma? The two only overlapped, using Lange’s chronology and the dates in the Kano Chronicle, c. 1564-1565. Dierk Lange has suggested that the conflict with Kano occurred early in Idris b. Ali’s reign, perhaps in c. 1564, but other sources suggest the mai went on a pilgrimage to Mecca at this time.[3] Since our dates for Kisoki and Idris Alooma are approximations and other king lists of Kano give Kisoki’s predecessor a slightly longer list, one could possibly make the case for a longer period of overlapping reigns.[4] The other problem with Kisoki’s Borno conflict occurring during the reign of Idris Alooma is the praise song mentioning his grandmother, Hauwa. She could have been alive in the 1560s as a very aged woman, but some may prefer to date this period of conflict to an earlier decade in Kisoki’s lengthy reign.

The other issue with establishing a clearer chronology is the, quite frankly, mess made by previous generations of scholars interested in this part of the world. For instance, M.G. Smith, without a single source to back his speculative reasoning, suggested that Kisoki’s raiding of Borno territory may have been done in conjunction with the Kanta of Kebbi. Without any firm evidence and relying upon later sources and traditions of the power and stature of the Kanta in this part of West Africa, Smith has argued that Kisoki may have been the Kanta’s representative in central Hausaland. Consequently, Kisoki’s raid may be associated with Kebbi’s larger conflict with Borno. Building this possible theory on flimsy foundations, Smith then tentatively dates Kisoki’s attack on Nguru to 1544.[5]

Although Smith is merely suggesting possible regional scenarios to contextualize the wars and raiding between the major states in the Central Sudan, this is hardly supported by the source materials. While Muhammad Bello in the 1800s wrote of Kebbi conquering other Hausa states like Kano in the 1500s, it is very difficult to detect any of this in the Kano Chronicle or the Bornoan records. The Chronicle actually portrays Kisoki as the ruler of all of Hausaland. Indeed, according to this same source, “He waged war on Birnin Unguru because of Agaidam.”[6] This last word brings to mind Geidam in modern Nigeria, to the east of Nguru. This area may have been a source of contention as Borno was facing an extended famine during Abd Allah b. Dunama’s reign (c. 1557-1564).[7] This could have been influenced by the wars between Borno and Kebbi, as well as the distractions Borno faced from the Bulala to the east in Kanem and local revolts by the Sao in Borno and other groups. Seeing an advantageous position to strike, Kisoki (or perhaps his grandmother’s brother, who was extremely influential in the royal court) may have envisioned Kano extending further east. Certainly, booty in horses and textiles were desirable since Kisoki ordered no captives taken from Nguru.

Furthermore, utilizing all the various sources on the Kanta of Kebbi and his negative relations with Borno suggests a large-scale confrontation in which Borno attempted to besiege Surame took place in c. 1561. Traditions referring to this do not reference Kano at all. In fact, it was on Katsina territory the Bornoan forces engaged in combat with the Kanta.[8] This is highly suggestive of Kano’s actions against Borno likely being autonomous responses of the state to Borno and perceived weaknesses on its western borderlands with Kano.

For these aforementioned reasons, one is inclined to agree with Yusufu Bala Usman. Usman, in a largely insightful article on the history of relations between Borno and the Hausa states, correctly identified Kisoki’s raids with the ones described by Ahmad b. Furtu. Moreover, as Furtu writes, these raids were a “betrayal” by the people of Kano. As for the Kano Chronicle, Kano attacked Nguru because “it is the will of God.”[9] Usman’s reasoning here is not entirely clear, but the raids from Kano and the reference to the building of walls or fortifications around various towns in the Kano kingdom  are consistent with the actions of Kisoki. After all, by improving defenses on his eastern frontier, forces from Kano could more safely engage in raids or attacks on western Borno or its vassal provinces, then retreat to secure sites if pursued or followed. Over time, this could have led to a gradual increase in Kano’s influence and possible territorial gains to the east. One suspects the “will of God” as a justification of war was designed to show Kisoki as waging just war against various subject peoples of Borno who were not necessarily Muslims.

Agreeing with Usman also allows one to gain some insight into how both sides viewed their actions. One already knows the Borno perspective, even if Ahmad b. Furtu was not an eyewitness to the Kano campaign. He nonetheless wrote an explanation for the campaign based on Kano and its fortified towns like Kirza, Kalmasan, Majiya, Ukluya, Dulu, Awazaki, Ajiyajiya, Sa’iyya, Galaki and Kay. To Furtu, they not only fortified many settlements, but “resorted to abominable cunning and vile deeds.”[10] The conflict ended with the “many” expeditions launched against Kano, including Majagani. These expeditions led to the destruction of fortifications while the residents fled. Unfortunately, most of these expeditions are not described in detail and after the destruction of Majiya’s fortifications, the Bornoan forces were allegedly able to dismantle the walls and fortresses placed around other towns with little or no resistance. It is very unlikely that the ruler of Kano would have sat idly by, even if the musketry of Borno proved very effective against Majiya’s defenders. Overall, Furtu’s account seems to suggest Kano began this process of fortifying towns and launching raids before the reign of Idris Alooma, especially since the labor and resources necessary to build walls around several towns or cities could hardly have been accomplished in a short amount of time.

The Kano Chronicle, likely written in the late 1800s, lacks this level of detail but understandably highlights the moment of Kisoki’s victory as Borno failed to take Kano city. As previously mentioned, Muhammad Kisoki ordered the raiding of Nguru, a town which was the capital of the powerful galadimas of Borno by the 1600s. Murray Last has read the account of this as symbolic warfare, playing with the idea of the Kanuri word for the Hausa, afuno, and arse-clothes or nudity. After all, Kisoki did not take captives but focused on horses and clothes.[11] However, this symbolic meaning may not be relevant if Kisoki was endeavoring to present himself as a legitimate Muslim ruler not willing to take Muslim captives. Indeed, even Ahmad b. Furtu portrayed his patron similarly. Next, the Chronicle explains how the ruler of Borno then sought to attack Birnin Kano the following year, but failed to take the town. This led to an extended praise song which even included Maidaki Hauwa as the “old lady with swaggering gait, old lady of royal blood, guarded by men-at-arms.”[12] By praising Kisoki as the “physic of Bornu and the Chiratawa,” one can also surmise that Kano’s war with Borno involved Shira. Despite this victory of sorts, or at least the failure of the attempted assault on Kano, Kisoki invited prominent shaykhs from Borno anyway.[13] One may surmise here that Borno was still perceived as a source of reputable Islamic scholars and religious figures, Kano’s rulers were entrenching their own state legitimacy through war and Islam.

Ultimately, both sides could claim some degree of victory. Kano was able to withstand a military attack on its capital from its powerful neighbor. Borno, on the other hand, secured its western frontier by destroying fortifications and weakening Kano’s ability to launch deeper raids into Borno. Doing so inevitably aided the economy through the increased security for traders and travelers. It likewise made it easier for Borno to focus on internal rebellious groups and the Bulala to the east for a number of Kanem expeditions. Kano, meanwhile, was able to protect its capital and, unlike Abdullahi, Kisoki did not have humble himself before the mai. This expresses a growth in the political stature of the sarki who could meet the Sayfawa as a peer. Lastly, an attempt at revisiting the various sources on this encounter does support Kisoki’s raiding activities to the east as likely to be the same as those mentioned by Ahmad b. Furtu. Furtu’s account is too brief and not backed by eyewitness testimony. But based on the scale of operations and the necessary shovels, hoes, and implements to destroy town walls at various sites and then to attack Kano’s capital, the Kano expeditions must have been large and time-consuming.

Pondering the Origins of Kano's Maidaki Hauwa

 

What were the origins of one of the most powerful women in the annals of Kano history? This question is directly pertinent to questions of marriage alliances, the growing power of queen mothers or royal women, and the relations between Kano and other powers. Indeed, in the case of Maidaki Hauwa, it would go on to shape the reign of no less than 6 kings of Kano. This brief post shall explore the competing theories and defend the Gaya hypothesis for Hauwa’s origins.

According to one Kano chronicler, el-Arabi, Hauwa was the daughter of the ruler of Gaya, Agalfati (or Aganfi).[1] Unable to locate the text of this chronicle, one suspects el-Arabi connected Hauwa to Gaya’s ruler because Agalfati’s name appears in the Kano Chronicle before the reign of Muhammad Rumfa. In addition, some oral traditions associate Muhammad Rumfa with Daura and Gaya. According to Dokaji Alhaji Abubakar, Rumfa allegedly spent time in Gaya before coming to Kano.[2] This may have influenced el-Arabi’s account, perhaps suggesting an important alliance between Gaya and Rumfa. M.G. Smith, on the other hand, proposed a Gaya origin for Muhammad Rumfa’s mother, Fatima.[3]

Whatever the case may have been, the Rumfawa were linked to the powerful rulers of Gaya. Indeed, the Kano Chronicle also connects Agalfati with Machina, an important town whose rulers claimed ties to the Sayfawa.[4] The legendary story of origins for Machina’s kings claims their ancestor was a half-brother to a Sayfawa mai, the son of the first to rule from Gazargamo.[5] Interestingly, the kings of Machina resided in a palace of brick, a symbol of royal authority or status in Kanem and Borno. This suggests that the legend may be accurate in at least identifying an important connection or status with regard to Borno’s ruling dynasty. If the Gaya ruler Agalfati really was a son of the king of Machina, they may also have once been in the orbit of Borno. Much more information is needed to clearly establish this. For example, oral traditions cited by Muhammad Jamilu Abba link Gaya’s foundation to migrants from Jibede in the Dutse Gadawur territory.[6] Either way, traditions associating with Rumfa with Gaya may have influenced el-Arabi’s belief in Hauwa’s Gaya origin. An alliance sealed through marriage with Gaya’s chiefs may have been essential in gaining access to the throne for Rumfa. After all, Gaya had already proven its power through its involvement in the deposition of Umaru (1410-1421).[7]

The other theory, of a Songhay origin, is highly unlikely. Proposed by Murray Last, the only source for this notion is Leo Africanus. Per Africanus, the Askia of Songhay (Askia Muhammad I) supposedly conquered Kano and other parts of Hausaland. After defeating Kano’s ruler, he then made the Kano king marry his daughter.[8] But there are many problems with this theory. First, if one accepts 1493 as the date of Askia Muhammad’s accession to the throne of Songhay and 1499 as the year of Rumfa’s death, it is hard to imagine Maidaki Hauwa and Rumfa would have had a son old enough to become king of Kano in 1499. There’s also the issue of the Kano and Songhay sources making no mention of this at all. The Tarikh al-Sudan does refer to Songhay invasions of Agadez, conflict with Kebbi, and a 1514 raid on Katsina. But these events took place long after the death of Muhammad Rumfa. Furthermore, when Songhay sources do allude to Kano, such as Ali Fulan’s flight there in 1529, there is no mention of Songhay conquest or forcing the payment of tribute.[9] Perhaps the flight of prominent individuals from Songhay to Kano is additional evidence of the lack of any subjugation of the latter by the former.

Moreover, the description of Kano by Leo Africanus is more consistent with the reign of Abdullahi, Rumfa’s son. Africanus accurately noted that Kano had achieved military success against Katsina and Zaria.[10] Thus, the usually accepted chronology as well as the written sources and relevant traditions from West Africa do not support this theory. Consequently, if Leo Africanus is reliable at all, the Askia would have forced Abdullahi to marry his daughter. The “obvious candidate” for the Askia’s daughter would then become Lamis, a remarkable woman who significantly shaped events in the reign of Muhammad Kisoki.

            In addition, some sources from Kano support a Hausa origin for Hauwa. Translated lists of kings from manuscripts even name her father. According to one, he may have been Babari.[11] These lists are hardly conclusive evidence, but they could be interpreted as additional evidence against the Songhay origins theory for Hauwa. Against this must be considered other manuscripts which name Abu Bakar’s mother as Kuyina or Ukin.[12] But the lists do not readily support a Songhay origin or any ties to Askia Muhammad. Even Lamis, whose name is rendered in one manuscript as Lamis Tamajikanna, is difficult to connect with the Songhay.

The queen’s ability to ensure her son succeeded and that her brother began to exert a strong influence on the royal court of her grandson, one which seems to overlap with Gaya and eastern Kano interests, lends some support to the theory of Gaya origins. A pattern in later Kano-Borno relations can be detected across the centuries in the Kano Chronicle. One notes a tendency of Gaya’s ruling family trying to dominate Birnin Kano’s court and the development of policies which favor Gaya or suggest anti-Borno stances. To the extent that one accepts Barkindo’s theory of Rumfa’s caliphal ambitions as a challenge to the primacy of Borno and Songhay, this could have facilitated an alliance between anti-Borno Gaya and Rumfa. Indeed, a later era of Gaya influence in Kano’s court apparently led to the creation of new towns with additional walls, prompting a Borno campaign in the 1730s.[13] This is quite similar, apparently, to what transpired in Muhammad Kisoki’s reign, according to glimpses from Ahmad b. Furtu’s chronicle and the Kano Chronicle.

Perhaps the Gaya origin theory of Hauwa is still missing crucial support in the sources, but it does have a logical basis. Furthermore, it elucidates, or proposes a theory, for why she may have become the first Mai Daki or Babar Daki, with great powers and her own retainers. Her high status in Rumfa’s reign, or at least those of their son and grandson, could have begun through a close alliance with Gaya. Alternatively, she could have come from Dutsi or another powerful chiefly lineage in Kano or another part of Hausaland. But the Gaya theory “fits” best with what historians have been able to reconstruct of the Kano state in this period. The Songhay princess theory has little to no support in the sources or in the usually accepted chronologies.

Love Hangover


Was pleasantly surprised to see that "Love Hangover" was written by Alice Coltrane's sister, Marilyn McLeod. Not exactly too shocking considering their Detroit origins and origins in a musical family. Even with the vastly different styles, one can still detect shared roots in Detroit's black music.

Africans and Amerindians in Late 1500s Hispaniola

 

Whilst perusing Gallica's Collection Moreau Saint-Méry again, we were reminded of a series of French translations and notes on the history of the black race on the island of Hispaniola. Entitled De l'introduction des nègres à Saint-Domingue de leurs révoltes, de leur traitement, etc., it essentially covers 1502 to the early 1700s, including both the Spanish and French colonies. 


Included in it are two laws from 1573 and 1589. Both are intriguing for the tiny glimpses they provide into relations between people of Amerindian and African descent in the colony. Of course, by 1573 and 1589, there likely were not many people on the island counted as "Indian." Presumably, this included remnants of the aboriginal population of the island as well as captives and others from different parts of the Americas. Nonetheless, the 1573 law implies that people of African and indigenous ancestry were having children together, raising questions about the tax responsibility of their progeny. The later law, from 1589, implies that free and enslaved blacks were, at least in some cases, exploiting and treating indigenous women as concubines.

Ghana Nila


Listening to more of Alice Coltrane's discography revealed a funky, soulful version of "Ghana Nila." This is perhaps closer to something Coltrane's sister would have written, yet so consistent with her approach to spirituality and the ashram she began in California.

Banning Enslavement of Caribs (1739)

 

Whilst randomly perusing Gallica and other sites, we came across Copie d'un ordre du roi interdisant de réduire en esclavage les Indiens Caraïbes, a royal declaration banning the enslavement of Caribs or Kalinago peoples in the French Caribbean. Dated 1739, it obviously did not completely ban or outlaw the enslavement of Kalinago and other indigenous peoples. After all, "Caribs" even appear in some of the runaway slave notices in Saint Domingue from later decades.

Biu, Kwararafa, and Borno

Although we still have not located a copy of an important study of Kwararafa by Webster, reading a thesis by a student of his, John E. Miller, has been informative. Miller's thesis, The Biu Plateau: Establishing a Chronology and the Linkages Between Bura-Babur and Kwararafa, attempts to interpret oral traditions and the few written sources available to contextualize Biu in the larger context of Kwararafa and Bornoan history. In so doing, the author draws from colonial-era reports and collections of traditions by authors like Meek as well as written sources included in works like Palmer's Bornu Sahara and Sudan. Pushing back against attempts to read the earlier phases of Kwararafa as a heavily Jukun-influenced entity, Miller follows Webster in situating Kwararafa's second phase capital at Tagara (after being driven out of Santolo). It is this earlier context which elucidate things like the royal crocodile totem observed by many groups in the Biu region and along the Gongola, not the supposed Jukun influence reaching this area earlier. 

While pushing back against the Jukun readings of Kwararafa, Miller also tries to tentatively date the arrival of Yamta in Biu. Drawing on somewhat contradictory traditions, which also make Yamta a Bornoan prince from Gazargamo who left after some sort of succession dispute, Miller suggets a date of c. 1519-1546 for reign of Yamta in Biu. Citing Palmer, who reported traditions of Ali b. Dunama defeating Kwararafa, Miller argues that Yamta arrived in the region after Kwararafa abandoned the capital at Tagara to move south to cross the Benue. This meant the region was possibly politically divided or in a state of transition, facilitating the establishment of new chiefdoms in the area. But, critically, the previous ruling lineages who were influenced by or part of Kwararafa may have retained some influence as priestly clans or lineages. The evidence for this is still fragmentary, but observing totems, clan and lineage moieties, as well as commonalities between cultures associated with the later Kwararafa phases and those in regions like Biu, Miller thinks his model is plausible. 

Naturally, Miller's chronology and model here relies heavily upon Webster, whose notion of different phases of Kwararafa we have yet to examine. Miller is also assuming that the Sayfawa mai named in the traditions about Yamta, Idris, is Ali b. Dunama's son, who reigned (in Lange's chronology, 1497-1519). A firmer date is provided by Ahmad b. Furtu, whose account of Idris Alooma's wars refers to Yamta's chiefdom aiding in the attack on Amsaka. Using average regnal lengths and the date of Idris b. Ali, Miller has one of the few confident dates in his chronology. He's also assuming that Kwararafa's later capital at Biepi only began after c. 1485 (and with a Kanuri or more likely, Babur, dynasty by the 1520s) and only after the mid-1700s did the Jukun come to dominate Kwararafa. All of this could be plausible, but we need additional data on the Bura, Kilba, Marghi, Chibbuk, and other peoples to adequate test the proposed chronology of Miller. Hopefully future scholars will consult the more recently published studies on this region and try to incorporate more of the written sources from Vatican archives or European reports of the 1600s and 1700s. These could aid in proving or weakening the chronology adopted here...
