The battle of Kousséri was a major engagement fought between France and the forces of the warlord Rabih az-Zubayr in the Rabih War. The conflict originated in French plans to occupy the Chari-Baguirmi region in modern-day Chad. In 1899–1900, the French organized three armed columns, one proceeding north from Congo, one east from Niger and another south from Algeria. The objective was to link all French possessions in Western Africa, and this was achieved on April 21, 1900, on the right bank of the Chari in what is now Chad opposite Kousséri, in what today is northern Cameroon.
