Belgium is the limit case of "every empire did it". Every other empire was bigger, longer, and more diversified. None matched it for deaths-per-square-mile[1].

Phase one
The Congo Free State, 1885–1908
Leopold II secured personal sovereignty over the Congo basin at the Berlin Conference of 1884–85, using the front organisation he called the Association Internationale du Congo. He marketed the territory as a humanitarian and free-trade project; he ran it as a forced-labour monopoly in wild rubber and ivory, enforced by the Force Publique through hostage-taking, mutilation, and direct killing.
The campaign by E. D. Morel, Roger Casement, Mark Twain (King Leopold's Soliloquy, 1905), and Joseph Conrad (Heart of Darkness, 1899) forced Belgium to annex the territory in 1908. For the full deep-dive see the Congo Free State page.
Phase two
The Belgian Congo, 1908–1960
The state replaced the king. The mutilations stopped; the extraction did not. Forced labour continued through head taxes, the chicotte, and the recruiting practices of Union Minière du Haut-Katanga (copper), Forminière (diamonds), and Huileries du Congo Belge (Unilever palm oil). The Congo's mineral wealth fuelled Belgian and Allied industry; uranium from the Shinkolobwe mine supplied the Manhattan Project[9].
“The Congolese were prepared neither for self-government nor for independence. Belgian education, in the rare cases when Africans received it, was vocational.”
On the eve of independence in 1960, the Congo had perhaps thirty Congolese university graduates and not one African doctor, lawyer, or army officer. Patrice Lumumba, the first elected Prime Minister, was assassinated within seven months with the documented complicity of Belgian and US intelligence.
Phase three
Ruanda-Urundi, 1922–1962
Taken from Germany at Versailles and held under League of Nations mandate, then UN trusteeship, Ruanda-Urundi was the laboratory of bureaucratic racial classification. Belgian administrators issued identity cards categorising every resident as Hutu, Tutsi, or Twa — a categorisation that previously had had economic and social fluidity. The 1994 Rwandan genocide did not need this paperwork to occur. It used it.
What survives it
Brussels, Tervuren, the silence
The wealth extracted from the Congo built the Arcades du Cinquantenaire, the Royal Museum for Central Africa at Tervuren (only re-opened post-decolonial in 2018), the Ostend seaside developments, and large parts of the Belgian rail network. Belgian state apologies — including King Philippe's "deepest regrets" letter of 2020 — have not used the word excuses ("apology") and have not opened reparations.
