The one battle of the Sokoto jihad with any specific casualty figure attached to it is the Battle of Tsuntua in December 1804, an early defeat in which roughly two thousand of dan Fodio's men, including two hundred who had memorized the Quran, were overrun by Yunfa's army. No historian has attempted a war-wide total covering the four years of campaigning that followed across Kebbi, Katsina, Daura, Kano and Gobir, nor the civilian toll of a conflict that reorganized the political map of the entire Hausa-speaking region, and this atlas records the toll as unknown rather than adopt the one documented battle figure as a war total.
The jihad was fought as a program of Islamic reform rather than a change of rulers alone. Dan Fodio's declaration of jihad after the 1804 hijra to Gudu invoked the classical Islamic vocabulary of a community of believers compelled to flee persecution before taking up arms, and the caliphate his forces founded was organized explicitly as an Islamic state governed under sharia, with his own extensive religious and legal writings serving as its intellectual foundation until his son Muhammad Bello succeeded him in 1817.
