Several power-sharing agreements have been reached in Africa over the last decades. This project has compared the experiences of various forms of power-sharing in five countries, Burundi, Kenya, Liberia, Nigeria, and Sierra Leone. The cases differ significantly both with regard to the implementation of power-sharing and the rationale for adopting such institutions. Our conclusions is that power-sharing institutions have proven themselves useful in some countries and less so in others. The most positive experiences have been in the peace processes of Sierra Leone and Liberia, where power-sharing played a vital role in securing peace. There are less clear support for power-sharing institutions with regard to good governance.
