French West Africa with the exception of the Senegalese Communes, the administrative structure of French rule at the lower levels remained constant, based upon the Cercle system. This was the smallest unit of French political administration in French colonial Africa that was headed by a European officer. They might range in size, but French Sudan (modern Mali) consisted of less than a dozen Cercles for most of its existence. Thus, a Cercle Commander might be the absolute authority over hundreds of thousands of Africans. A Cercle consisted of several cantons, each of which in turn consisted of several villages, and was almost universal
Sudan In the 1890s, the British sought to re-establish their control over Sudan, once more officially in the name of the Egyptian Khedive, but in actuality treating the country as a British colony. By the early 1890s, British, French and Belgian claims had converged at the Nile headwaters. Britain feared that the other powers would take advantage of Sudan's instability to acquire territory previously annexed to Egypt. Apart from these political considerations, Britain wanted to establish control over the Nile to safeguard a planned irrigation dam at Aswan. Herbert Kitchener led military campaigns against the Mahdist Sudan from 1896 to 1898.
