The correct answer is the clash of European powers in controlling Africa
The 1898 Fashoda Incident was one of the crucial conflicts for Europe to consolidate its possessions on the African continent.
It took the United Kingdom and France to the brink of war but culminated in a great strategic victory for the first, and laid the groundwork for the 1904 "Entente cordiale" among rival nations.
The conflict arose out of some battles over control of certain regions on the Nile, due to the expansion of the United Kingdom to Sudan.
The French advance into the interior of Africa came from West Africa towards the east, through the Sahel, bordering the south of the Sahara, a territory that currently encompasses Senegal, Mali, Niger and Chad.
Its main objective was to obtain an uninterrupted link between the Niger River and the Nile, in order to control all trade in the Sahel region, due to the existing control over the caravan paths that crossed the Sahara.
