The Lāmīb̳e of Fombina : a political history of Adamawa, 1809-1901 by Sa'ad Abubakar analyzes the rise and fall of a jihadist state founded by the Fulbe, or Fulani, in the vast region of Fombina. Unlike other emirates within the Sokoto Caliphate, Fombina lacked a prior history of political centralization. Instead, the large province was shared by a plethora of ethnic groups living in small chiefdoms. The Fulani int he area, who already had a presence by the 18th century, were also divided into smaller clan and lineage groups. While Borno and Mandara had some degree of influence in the area through trade, raiding and conquest, and the Jukun state appears to have exerted some degree of influence there previously, Fombina's non-Fulbe lived in "theocratic" chiefdoms and small-scale polities. Long-distance trade was limited and the Fulani in the pre-jihad period lived under the dictates of the non-Muslim, non-Fulani sedentary populations. That said, the Fulani themselves were only weakly Islamized prior to the 19th century, preferring to live by pulaku and customary laws and tradition rather than Islamic ones.
Nonetheless, events in the 19th century led to a rapid transformation of this area, turning it into one of the largest yet most decentralized emirates of the Sokoto Caliphate. The jihad in Fombina, propelled by Modibbo Adama, was strengthened by incoming Fulani migrants who were fleeing Borno after al-Kanemi's victories against Gwoni Mukhtar and other jihadists. In addition, some of the Fulani clan leaders led an expansion into the southern areas to claim new pasture and lands, subjugating pagan sedentary groups. By the 1840s, with a capital established at Yola, the Adamawa emirate was a large, decentralized state with various sub-emirates that largely acted independently of Yola. According to Abubakar, this decentralized nature of Adamawa was due to the incomplete conquest of the Habe populations in the region (many rebelled and sometimes cut off loyal provinces) and the resistance of Fulani Ardo'en and sub-emirs to obey the emir in Yola. While tribute and participation in the military campaigns of the emir were expected and could be gained from loyal provinces, southern sub-emirates often ignored or rebelled against this. In addition, not all Fulani clans were included in the Adamawa leadership, and Islam itself was not widely practiced or observed by the Fulani. Thus, some ignored or disobeyed the emir at Yola. This problem only worsened as some of the sub-emirates experienced dynastic crises or internal wars over succession, a problem the ruler at Yola could not always alleviate.
Ultimately, by the end of the century, the partition of this vast, loosely joined state was inevitable. British, French and German interests in the Benue and Chad Basin made its longevity numbered. The state, to its credit, was able to consolidate some of its gains and implement a real administrative machinery (with titles borrowed from Hausa and Kanuri, as well as other parts of the Sokoto Caliphate), and the use of slaves for food crop production and the promotion of trade (particularly ivory) did promote some degree of economic development and improvement in conditions for Fulani and allied leaders. Furthermore, the invitation extended to Muslim scholars and pilgrims attracted a larger class of pious Islamic leaders, who in turn promoted a deeper spread and adherence to Islam. Earlier in its existence, it also scored victories against Mandara and was able to protect its northern border with Borno. The state was even able to survive the Mahdist movement and the Sudanese warlord, Rabeh, ultimately falling to the European powers.
The central theme here appears to be one in which the incomplete centralization of the Adamawa Emirate hindered its ability to establish a stable political system. Of course, This uneven centralization of the state appears to have been a result of the region's lack of such a system before the 19th century, as well as the particular nature of Fulbe society and political traditions. Thus, instead of a jihadist state that had the political traditions of Hausa states with centuries of political traditions, Modibbo Adama and his successors had to create one wholesale, borrowing from the ideals of the Sokoto Caliphate, Borno, and Hausaland. Indeed, Adama is said to have studied and lived in Borno and adopted some of its titled positions in his administration, testifying to the importance of these older political systems in Adamawa attempt at reforms. Abubakar likewise endeavors to include pagan, non-Fulbe peoples as part of this story, albeit their perspective is more dependent on oral tradition and often lost in the entangled histories of the various sub-emirates.
