Usman dan Fodio, born in 1754, joined a growing number of traveling
Islamic scholars through the Hausa kingdoms in the 1770s and became quite popular in the 1790s. In the late 18th-century, the
Galadima of Bornu, Dunama, administered a large district in western Bornu, which contained numerous Fulani groups and encompassed portions of what later became the emirates of
Hadejia,
Katagum,
Jamaare, and
Misau. Three figures led the jihad in this area: Bi Abdur, Lerlima, and Ibrahim Zaki. Bi Abdur lived near
Hadejia and, around 1800, persuaded the Sarkin Hadejia (ruler of Hadejia) to appoint him as the leader of the local Fulani. He had considerable animosity towards the Galadima, who was responsible for his father's death. Lerlima, Bi Abdur's maternal cousin, was married to the Galadima's daughter and served in his administration, possibly as a tax collector. Ibrahim Zaki was a widely travelled
mallam (Islamic teacher) and was familiar with the teachings of Shehu Usman. To the south of the empire, a similar situation existed. The jihad was primarily led by Fulani groups centered at Deya (today in
Gujba,
Yobe State). During the late 18th-century, the local ruler of Deya, Muhammad Lafia, "because of his recalcitrant ways" was deposed by the Mai of Bornu, Ahmad. He was replaced with his younger brother, Muhammad Saurima, who the Mai hoped would be more cooperative. The local Fulani leadership, including two learned men, al-Bukhari and
Goni Mukhtar, was displeased with Lafia's deposition as he had maintained friendly relations with the Fulani. ==Battles==
