Katanga secedes

11 Jul 1960 — Backed by Belgium’s Union Minière, Moïse Tshombe declares the copper-rich south independent. A secession defending a mining fortune, not a nation — the UN’s first war will take four years to end it.
THE MOMENT IN CONTEXT
If Nigeria showed independence’s best hopes, the Congo showed its worst nightmare — and it happened in five days. Belgium had ruled its enormous central-African colony with brutal paternalism and had done almost nothing to prepare it: at independence on 30 June 1960 there were a handful of Congolese university graduates and not one African army officer or senior administrator. Watch the map: within a week of Patrice Lumumba’s defiant independence speech, the Force Publique mutinied against its Belgian officers, Belgium sent troops back in “to protect its nationals,” and the copper-rich province of Katanga — bankrolled by the Belgian mining giant Union Minière and led by Moïse Tshombe — declared secession (the frontier line and the arrows). The new state came apart before it had begun to function.
From Chapter 6 — The Congo Crisis of The Decolonization of Africa, 1945–1994 (JUL 1962).

Then ask the room: Was the Congo catastrophe caused mainly by Belgian misrule, by Cold War intervention, or by the Congo’s own divisions — and why does it matter which? The argued answer is on the chapter page →
