Techniques of military conquest in the Sudan spread to govern the entire federation.

Evidence

The conquest of the Western Sudan would prove pivotal in determining the ideology and actions of the civilian government in West Africa until World War I. In the years immediately following Samori’s defeat in 1899, several newly appointed lieutenant governors began to apply the principles of “direct” administration, worked out in the Western Sudan, to other colonies of the federation, even in areas where protectorates already existed. For example, the king of Dahomey and the Fulani Almamys saw their states subdivided into cantons of more or less uniform size, and their prerogatives considerably reduced. — Alice L.
