This title was first published in 2002: Examining the recent phenomenon in conflicts in Africa, this text addresses situations where African states and African military intervene in conflicts either in neighbouring states or beyond. While this trend has been widely observed, this is the first in-depth research that deals with such issues. It breaks new ground in identifying the key issues, actors and actions, and includes analysis of military capacities of African states and the way in which armies are used, including the increasing role of private security companies and mercenaries. The changing attitudes among members of the OAU are examined, in particular the increasing acceptance of interventionism and the blurring of boundaries. The most significant cases of intervention are examined together with less well-documented examples such as Lesotho and Guinea Bissau. This engaging account makes for a compelling resource for academics and practitioners alike.
