This study addresses a longstanding and renewed subject in the case of Sudan: the continual interference of military formations and elites in political authority and the instability of post-independence civil governance. It uses a compound methodology blending a historical reading of political events and developments with a descriptive reading of the present reality, in its domestic and foreign dimensions, and a forecast of Sudan's future in light of the current situation. The study observes that the plurality of regional, ethnic, and military structures, instead of being a constructive and integrating aspect of the Sudanese state and nation, has reflected negatively on the country's unity and its political and security stability. Since independence, these formations have remained in confrontation, whether between one another or among the internal parts and divisions of each. Evidence for this claim is found in Sudan's complex crises, including that of governance, the South, Darfur, the current transitional period, and the struggle for power presently raging between military branches.
