States Designed for Conflict: Colonial State Formation and the Structural Reproduction of Violence: Evidence from Rwanda and the Eastern Democratic Republic of Congo

Persistent conflict in Central Africa—and across post-colonial states more broadly—is not the product of episodic crises, contemporary leadership failures, or random instability. It is the structural legacy of colonial state design. This article identifies a central mechanism—annexation without incorporation—through which colonial border-making produced populations formally subjected to state authority but denied enforceable rights, political membership, and protection. Such populations experience durable structural insecurity and, over generations, mobilize in predictable ways, generating recurrent, frequently cross-border conflict. A comparative analysis of multi-border and compact states illustrates the mechanism. Fragmented colonial borders in the Democratic Republic of the Congo (DRC) institutionalized political exclusion and territorial fragmentation, producing persistent armed groups and externalized insecurity. Rwanda, by contrast, internalized authority within a compact territory, resolved internal instability while remaining exposed to unresolved vulnerabilities among politically excluded populations beyond its borders. Historical evidence shows that colonial annexation and administrative incorporation without political integration were systematic, not accidental, features of state formation. In eastern Congo, communities historically connected to Rwanda and local polities were annexed without full membership, creating enduring zones of exclusion that continue to structure violence. The mechanism generalizes beyond the Great Lakes, as seen in cases from Sudan/South Sudan to Cameroon/Nigeria and Somalia/Ethiopia, where annexed populations remain politically marginal and structurally insecure. The article advances a historically grounded, mechanism-driven, and predictive framework for post-colonial conflict, demonstrating that persistent instability is not an aberration of weak states but the expected outcome of institutional design. Durable peace, therefore, requires structural remedies—legal recognition, political inclusion, secure land tenure, and regional coordination—rather than purely episodic interventions.
