First Mandingo War

By the late 19th century, Samori Touré had established the Wassoulou Empire across parts of present-day Guinea, Mali, and Côte d’Ivoire.^[1] The empire developed a centralized administrative structure and maintained a professional army equipped with firearms acquired through regional and trans-Saharan trade networks.

At the same time, the French Third Republic expanded inland from its Senegalese coastal territories, seeking control over trade routes and political influence across the Niger basin.^[2]

French attempts to establish protectorates and military posts in the Upper Niger region brought colonial forces into increasing conflict with Wassoulou-controlled territories. Diplomatic negotiations failed to produce a lasting agreement, and by the early 1880s, localized clashes escalated into sustained warfare.

The initial phase of the conflict consisted of small-scale engagements along contested border zones. Wassoulou forces used mobility, terrain familiarity, and coordinated raids to disrupt French positions.

French forces operated from fortified posts and relied on artillery and disciplined infantry formations but faced logistical challenges in inland operations.

The conflict intensified as both sides reinforced their military presence. Samori Touré reorganized his army into structured infantry and cavalry units, improving discipline and operational coordination.^[3]

French commanders, including Joseph Gallieni and Louis Archinard, implemented a strategy of incremental territorial advance supported by fortified supply routes and river transport networks.

By the mid-1880s, neither side achieved decisive victory. Wassoulou forces increasingly relied on guerrilla warfare tactics, including ambushes and strategic withdrawals, as well as scorched earth strategies designed to deny resources to advancing French troops.

French forces continued gradual occupation of strategic points, consolidating control over key administrative and logistical centers.

The war concluded with the signing of the Treaty of Bissandugu in 1886. The agreement established informal spheres of influence, allowing France to consolidate control over coastal and strategic regions while recognizing Wassoulou authority over portions of the interior.

Following the treaty, Samori Touré used the temporary stabilization to reorganize and expand his military and administrative systems. However, renewed French expansion in subsequent years led to further conflict. These later campaigns ultimately resulted in the collapse of the Wassoulou Empire and Samori Touré’s capture in 1898.

The First Mandingo War is interpreted by historians as part of broader resistance movements during the Scramble for Africa. It demonstrates both the military adaptability of West African states and the incremental nature of French colonial expansion in the region.

The historiography of the conflict reflects broader debates about the nature of colonial conquest in West Africa.

Early colonial-era accounts framed the conflict as part of a French “pacification” process, emphasizing technological superiority and minimizing African state capacity.

Later scholarship, particularly the work of Yves Person, reinterpreted the Wassoulou Empire as a centralized and adaptive state capable of sustained military resistance.^[1]

Modern historians such as Michael Crowder and contributors to the General History of Africa situate the conflict within longer-term processes of West African state formation, resistance, and colonial expansion.^[3]

A further historiographical issue concerns terminology, as “First Mandingo War” is not universally used in academic literature. Many scholars instead refer to a continuous series of Samori–French conflicts spanning the 1880s and 1890s.

Disagreement also exists regarding subordinate commanders within the Wassoulou military system. While figures such as Sory Ibrahim are relatively well documented, others such as Keme Braima appear inconsistently in the historical record and are treated cautiously in modern scholarship.
