This article summarizes the participation of the Congolese in the First World War. Unlike France, Belgium did not send a "Black Force" to the European front. Nevertheless, about thirty Congolese volunteered in Belgium and fought especially in Namur, Liège and on the Yser front. The Congolese fought mainly on the African continent, in Cameroon, Rhodesia and German East Africa. Thousands of Congolese soldiers and hundreds of thousands of Congolese, Rwandan, Burundian, Tanzanian, Kenyan and Ugandan porters took part in the military campaigns of the First World War in Africa. Thousands of soldiers and tens of thousands of porters died.
