Robin Law's The Horse in West African History is one of the indispensable studies anyone with an interest in Borno history must read. Although encompassing the entirety of West Africa, Borno frequently appears as one of the centers of the West African equestrian tradition. Not only was the imported, superior horse pivotal in the military expansion of Kanem and later Borno, but Borno became a center of horse breeding that likely was pivotal for the expansion of the Islamic-influenced technology to other regions, like Hausaland. The horse, as Law convincingly demonstrates, permitted a significant enlargement of the scale of political organization. The mounted warriors of states like Kanem-Borno were able to cover more ground quickly, pursue fleeing captives or defeated opponents, and, to at least a limited extent, build the power and prestige of rulers who provided horses or expensive equipment (quilted cloth armor, imported chainmail, saddles, stirrups). While horses must have been known in Kanem before the reign of Dunama Dibalemi in the 1200s, it was the introduction of stirrups and new technology that made the cavalry units of states like Mali and Kanem-Borno so powerful. Law's study elucidates this process with some provocative conclusions on the relationship of technology, tradition, and the state.
Although horses have been in West Africa for several centuries and a pre-Islamic tradition of horsemanship developed in areas of the northern savanna and the Jos Plateau, the widespread adoption of horses for military purposes in even the forested regions of West Africa illustrate the significance of the animal and new technology in the political economy of various states. States created by or at least associated with mounted warriors appeared among the Mossi and other parts of West Africa. Oyo, the subject of Law's dissertation, represents another example. In this case, a large Yorubaland state emerged whose expansion owed much to cavalry forces used with great success. Horses were so important and prestigious in West Africa that they became symbols of status for rituals, ceremonies, and even, as among the Igbo, objects of sacrifice. Due to their expense, especially in the forest regions where a reduced life expectancy meant replacements were always required, the horse became rightly associated with wealth, status, and power. The costs associated with feeding and maintenance could also be astronomical, again conveying the association of horses with political power and wealth.
In our beloved Borno, where the horse was bred by groups like the Shuwa, the horse was less expensive but a superior one with the finest equipment was still largely the preserve of the wealthy (and their free clients or slaves). After all, if Leo Africanus's confused account of Borno is reliable, fine horses acquired via the trans-Saharan trade were intimately linked to the slave trade, which in turn was linked to the state and its military apparatus in the procurement of captives for export. In fact, Law speculates that access to Dongola breed horses via Arabs migrating into the Lake Chad region may have been an additional factor in the Bulala driving the Sayfawa dynasty out of Kanem in the 1380s. So, clearly horses have played a huge role in the rise and fall of the Sayawa. In order to acquire the best quality of horses and equipment like chainmail, a brutal cycle of horse-slave trading developed. The horse becomes a key component of the political economy of war or the "ownership of the means of destruction" in which kings and powerful nobles armed warriors with the necessary mounts to produce the captives who then brought in more horses or luxury imports that could be redistributed to dependents or re-exported. This may have explanatory value for the "Sudanic" state in other parts of the Central Sudan and the savanna lands, even if it is not a perfect example of Aristotle's oligarchy nor a "feudal" system per se. One finds parallels for sure with Bagirmi, Wadai, and Darfur.
What is most interesting about this is the pioneer role of Kanem-Borno in the rise and fall of the horse's military importance. Kanem was likely one of the first of the early kingdoms to adopt stirrups and acquire access to North African or Dongola horses. And while Dunama Dibalemi's expansion of Kanem is also mentioned in the context of the vast number of horses he held, earlier rulers of Kanem may have possibly initiated the process of increasingly vital cavalry units for military purposes or lightning-quick raids on decentralized or political fragmented societies. Since Kanem was associated with the trans-Saharan slave trade as early as the 9th century, one would think horses were in use for at least slave raids if not in other military ventures. Unfortunately, until archaeological evidence or new textual sources emerge, our theory of Kanem as a pioneer is impossible to prove. Nonetheless, Kanem was certainly one of the early West African states identified by Law to adopt the mounted warrior as a central component of its army, which occurred by the 13th century. States in the Kanem-Borno sphere of influence in turn adopted or adapted cavalry in ways that reflect Kanuri influence, at least in the case of Bagirmi and perhaps Hausaland.
Borno under the Sayfawa were also pioneers in the early use of firearms. Everyone knows of Idris Alooma's use of muskets and even Turkish specialists brought in to assist with their implementation. Unfortunately, subsequent mais of Borno appear to have lost interest or the resources to maintain an important musketry corps in the army, although the occasional gift of muskets from Tripoli arrived during the reign of Idris Alooma's grandson. Soon, according to Law, the western part of West Africa and the coastal zones were the first to successfully make a permanent transition to firearms in the 1700s and 1800s. But Borno preceded these zones as early as the late 1500s, only to continue its reliance on horse warriors even into the second half of the 1800s. Why did Borno not maintain an active or at least notable musketry corps? The guns were still cheaper than fully equipped horses, and could have been utilized with enslaved soldiers to further centralize political power. Perhaps, as O'Fahey suggested in the case of Darfur, the greater mobility of cavalry was the primary factor. It is interesting, however, to note that the debate on political centralization and its relationship with a dominant cavalry or musketry is more complicated, but Borno, for a moment, was, during at least part of its "Golden Age" able to draw on both. The effective combination of the two could have cemented political centralization under the Sayfawa, although a corps of enslaved musketeers may have been too much of a threat to the dominant position of the cavalry and regional elites who supplied horses.
