For twenty-three years the territory we now call the Democratic Republic of the Congo was the legal personal property of one European monarch. It was not Belgian. It was Leopold II's[1]. He never set foot in it.

How it began
The Berlin Conference legitimised a king's private estate
At the 1884–85 Berlin Conference the European powers carved up Africa among themselves. Leopold II, working through the front organisation he called the Association Internationale du Congo, secured recognition for a territory of 2.3 million km² — roughly 76 times the size of Belgium — as his personal sovereign possession[1].
He marketed the venture as philanthropy: ending the Arab slave trade, bringing civilisation, opening Africa to free commerce. Within a decade it was a forced-labour regime built around a single commodity.
The rubber regime
Quotas, hostages, severed hands
With the 1890s bicycle and automobile boom, wild rubber became extraordinarily valuable. Leopold's administration imposed quotas on every village. The Force Publique — a 19,000-strong colonial army of Belgian officers commanding African conscripts — enforced them[2].
When a village failed its quota, the standard response was to take the women and children hostage in stockades until the men returned with rubber. The chicotte — a whip of dried hippopotamus hide — was the routine punishment. Twenty-five lashes was minor. A hundred lashes were often fatal.
Soldiers had to account for every cartridge issued. To prove that bullets had been spent on humans rather than wasted hunting, they brought back severed right hands — smoked to preserve them on the long return to the post. The hand quota became a regime in itself: when soldiers had missed or run out of cartridges, they cut hands from the living.
“The baskets of severed hands, set down at the feet of the European post commanders, became the symbol of the Congo Free State.”
The witnesses
Casement, Morel, and the first modern human-rights campaign
In 1903 the British consul Roger Casement was sent to investigate. His official report — published by the House of Commons in February 1904 — documented the regime case by case, naming villages, soldiers, and stations[3].
“The methods employed for the purpose of obtaining the natural products of the country are violent and arbitrary in the extreme … in the upper river district, the population has been reduced by one-half.”
E. D. Morel — a Liverpool shipping clerk turned investigative journalist — built the Congo Reform Association around Casement's evidence and the photographic record of Alice Seeley Harris, a missionary whose images of mutilated children circulated through Europe and the United States. By 1908 the international pressure was unanswerable. Leopold sold the Congo to the Belgian state for 215 million francs, plus 50 million for "personal sacrifice".

Why 10 million is the working number
What survived it
The wealth, the museums, the silence
The fortune Leopold extracted built the Arcades du Cinquantenaire in Brussels, the Royal Museum for Central Africa in Tervuren, the seaside resort of Ostend, and large portions of the Belgian railway network. The Belgian Congo that succeeded the Free State (1908–1960) was administered with greater bureaucracy but continued the forced-labour economy through different instruments — the head tax, the chicotte, and the missionary-supervised portage.
Belgium did not begin a serious public reckoning until 2020. King Philippe's letter to Congolese president Félix Tshisekedi that June expressed "deepest regrets" for the wounds of the past — without using the word apology and without offering reparations.
