The OAU’s decision to keep colonial borders is defended as the guarantor of African peace and attacked as the freezing of colonial injustice. Weigh the case.

THE SHORT ANSWER

• The border bargain of 1964. The OAU enshrined uti possidetis — colonial borders are inviolable — to prevent a continent-wide unravelling into secession and irredentist war. The logic was that any redrawing would open the door to endless claims; the cost was that peoples split by colonial lines (Somalis across five states, the Igbo, the Ewe) stayed split, and citizens were locked into states they had never consented to form. It was a conservative choice for stability over justice, and the debate over whether it was wise is unresolved.
• Economies inherited, not chosen. Independence changed the flag, not the economic structure: single-commodity exports at prices set in London and New York, no manufacturing, transport built to drain resources to the coast, tiny skilled workforces. The 1960s “development decades” and grand schemes (Nkrumah’s Volta dam, Tanzania’s villagization, Senegal’s groundnuts) often failed or disappointed because they were fighting a structure designed to keep Africa a supplier. When commodity prices fell, revenues and political stability fell with them.
• Why the coups came. Over forty coups by 1970 had common mechanics: armies were often the only organized, resourced institutions the colonizers had built; single-party rule removed peaceful ways to change governments; economic failure discredited civilian politicians; and ethnic and regional rivalries, frozen by colonial borders, found no other outlet. The soldier stepping in “to restore order” became the era’s recurring figure — sometimes reformer, more often simply the next strongman.
• Françafrique and the persistence of dependence. Formal independence often masked continued control. France in particular kept its former colonies tied through the CFA franc, defence pacts, troops, and personal networks (“Françafrique”) that installed and protected friendly rulers and intervened against unfriendly ones. Nkrumah called this neo-colonialism: political flags over economic subjection. It is why several “independent” states remained, in practice, clients — and why the map’s red does not tell the whole story.

WHAT IT CHANGED

Biafra: the border principle tested in blood. The Nigerian civil war was the OAU’s doctrine enforced at terrible cost — most African states backed the federation against secession, and the blockade that starved a million people was defended as the price of national unity. It set the precedent: Africa would not recognize secession (a rule that held until Eritrea and South Sudan, decades later). The famine is a memorial, not a lesson in strategy. Remember the children of Biafra.

One-party rule: rationalized and abused. Leaders from Nyerere to Kaunda argued that fragile new nations could not afford the luxury of divisive multiparty politics and needed unity under one movement. Made in good faith by some, the argument was seized by many others to justify dictatorship for its own sake. The record is genuinely mixed — Tanzania held together where others fractured — but the one-party state mostly delivered neither the development nor the unity it promised.

The borders hold — mostly. For all the internal violence, the striking fact is that Africa’s international borders barely moved. Even wars between states (Somalia-Ethiopia, Uganda-Tanzania) ended with the frontiers restored, not redrawn. The 1964 bargain worked as intended: it contained conflict inside states rather than between them — a stability bought at the price of freezing colonial injustice into the permanent map.
