Peaceful co-existence has remained elusive in some African countries due to myriads of internal armed conflicts. Relying majorly on desktop research, the study examined the role of mercenaries in the management of internal armed conflict in Africa. Findings reveal that the activities of mercenaries stand at daggers-drawn with the stability of African countries. Majorly driven by economic gains, mercenaries further worsen the conflict situation in their countries of operation. The study hence recommends among others that African countries should deepen peace-making strategies to forestall internal armed conflicts. The use of mercenaries should not be considered even in the face of full blown internal armed conflict.
