State collapse is one of the major threats to peace, stability, and economic development in sub-Saharan Africa today. In a collapsed state the regime finally wears out its ability to satisfy the demands of the various groups in society; it fails to govern or to keep the state together. The collapse is marked by the loss of control over political and economic space. A collapsed state can no longer perform its basic security and development functions and has no effective control over its territory and borders.Efforts to avoid drawing other nations into a wider conflict created by the collapse of a state—and creating favorable conditions for reconciliation and reconstruction of a failed state after it has collapsed—present major challenges. In April, 2008 the Cornell Institute for African Development called a symposium on ‘Failed and Failing States in Africa: Lessons from Darfur and Beyond’ to address these critical issues. Key contributions to the symposium are brought together in this volume. Taken together these essays represent a significant discussion on the challenges presented by the presence of failing states within Africa.
