King Leopold II and the Congo Free State: Forced Labour and Mass Death

King Leopold II and the Congo Free State’s Millions of Dead

King Leopold II of Belgium ran the Congo Free State as his personal property from 1885 to 1908. To extract ivory and, above all, wild rubber, his administration forced millions of Congolese people into labour, held their families hostage, burned villages and killed or maimed those who resisted. Together with famine, disease and a collapsing birth rate, this regime caused a population catastrophe. Historians' estimates of the deaths range from about one million to more than ten million; Adam Hochschild's widely cited figure is around ten million.

Yet outside Belgium and Central Africa, many people have never heard his name. This is the story of how a European monarch came to own a territory more than 75 times the size of his own kingdom, what happened there, how the world found out, and why the debate over his legacy is still alive.

Who was Leopold II?

Leopold was born in Brussels in 1835 and became King of the Belgians in December 1865. He reigned for 44 years, longer than any other Belgian monarch, and died in 1909. Belgium was a small, young country, and its politicians had little appetite for overseas colonies. Leopold, however, was convinced that a colony would bring wealth and prestige.

Before turning to Africa, he tried to acquire the Philippines from Spain in the 1860s and explored other schemes in Asia. When those failed, he looked to the vast and, to Europeans, largely unmapped Congo River basin.

How a king came to own the Congo

In 1876 Leopold hosted a geographic conference in Brussels and founded the International African Association, presented to the world as a scientific and humanitarian body that would explore Africa and fight the Arab-Swahili slave trade. Behind the language of philanthropy, it served his own territorial plans.

In 1878 he hired the explorer Henry Morton Stanley, who spent years setting up stations along the Congo River and gathering signatures from local chiefs on treaties that most could not read and that signed away land and labour. At the Berlin Conference of 1884–85, the European powers recognised Leopold's claim to most of the Congo Basin, partly as a free-trade zone and a buffer between British and French interests.

The Congo Free State was proclaimed in 1885. It was not a Belgian colony. It belonged to Leopold personally, ruled through agents in Brussels and Boma, and he never once visited it.

The rubber system: forced labour, hostages and severed hands

The early profits came from ivory. Then, around 1890, the invention of the inflatable tyre created huge demand for rubber, and the Congo's forests were full of wild rubber vines. Decrees in 1891 and 1892 declared nearly all land and its products state property. Large areas were handed to concession companies such as the Anglo-Belgian India Rubber Company (ABIR), and Leopold kept a vast Crown Domain for himself.

Villages were given quotas. In ABIR territory, adult men were expected to deliver several kilograms of dried rubber every fortnight, which in practice could mean most of every month spent deep in the forest. Farming, trade and crafts collapsed, and famine followed.

The quotas were enforced by the Force Publique, a colonial army of African soldiers led by European officers that grew to more than 19,000 men, alongside company sentries. Common methods included:

Hostage-taking. Women, children and chiefs were held in stockades until men brought in enough rubber. Deaths in these prisons were frequent.
The chicotte. A whip of dried hippopotamus hide; heavy floggings could kill.
Punitive raids. Villages that resisted or fell short were attacked and burned.
Severed hands. Soldiers were reportedly required to account for their bullets, and hands cut from bodies became proof of a "kill". Missionaries such as William Sheppard documented the practice; one of his reports in 1899 described 81 right hands being smoked for preservation. Historians still debate how often living people were mutilated, but the photographs of maimed children taken by missionaries became the defining images of the era.

The money flowed back to Europe. Revenue from the state's own domain rose from about 150,000 francs in 1890 to more than 18 million francs by 1901, and Congo profits helped fund Leopold's grand building projects in Belgium, though historians differ on exactly how much.

How many people died?

No census was taken at the start, so every figure is an estimate. The main ones are:

Adam Hochschild, author of King Leopold's Ghost (1998): about 10 million, drawing on a 1919 Belgian commission that judged the population had fallen by roughly half.
Roger Casement, the British consul who investigated in 1903: a decline of about 3 million.
Isidore Ndaywel è Nziem, Congolese historian: 5 to 10 million.
Other historians give lower ranges, and the anthropologist Jan Vansina warned that losses in the worst rubber districts cannot simply be extended to the whole territory.

Disease, especially sleeping sickness and smallpox, killed huge numbers in these years, and some historians weigh it heavily. Others point out that forced labour, hunger, displacement and violence made people far more vulnerable to epidemics, and that Congolese oral tradition blames the rubber regime. What is not in dispute is that the system caused mass death on an enormous scale.

Whether it should be called genocide is also debated. Most historians, including Hochschild, argue that the legal definition requires an intent to destroy a group, and that Leopold's regime aimed at profit rather than extermination. Hochschild still described it as one of the most appalling slaughters ever caused by human agency. Raphael Lemkin, who coined the word "genocide", and several later scholars have argued that the term does apply.

How the world found out

Leopold's propaganda was effective for years, but reports leaked out. In 1890 the African American journalist and historian George Washington Williams sent Leopold an open letter describing the abuses he had seen. Missionaries, including Sheppard, published accounts and photographs. The shipping clerk Edmund Dene Morel noticed that ships arrived in Belgium full of rubber and ivory but left for the Congo carrying mostly guns and officers, and concluded that the trade must rest on forced labour.

In 1903 the British House of Commons condemned the Free State, and Roger Casement's report confirmed the abuses in detail. Morel's Congo Reform Association became one of the first mass international human-rights campaigns, supported by writers including Arthur Conan Doyle.

In 1905 Mark Twain published King Leopold's Soliloquy, a 49-page satirical pamphlet in which an imaginary Leopold rants against missionaries and consuls while unwittingly exposing his own crimes. The publisher gave its surplus proceeds to Congo relief. The pamphlet is less familiar today than Twain's novels, but it was an important part of the campaign.

1908 and after

Under mounting pressure, Leopold handed the territory to the Belgian state, which annexed it on 15 November 1908 as the Belgian Congo. Belgium paid for the transfer, including a large sum to Leopold personally. Before the handover, the Free State's archives were burned. The worst abuses eased, but forced labour did not end overnight, and many of the same officials stayed in post. When Leopold died the following year, crowds in Brussels reportedly booed his funeral procession.

The Congo became independent in 1960. Leopoldville was renamed Kinshasa, and statues of the king were taken down.

Why so few people know his name, and how that is changing

For decades the Congo Free State was barely taught in European or American schools, and Belgium itself long celebrated Leopold as the "Builder King". That began to change after Hochschild's book became an international bestseller in 1998, followed by wider public debate in Belgium.

In June 2020, during Black Lives Matter protests, statues of Leopold in Belgium were defaced and authorities removed several, including one in Ekeren, Antwerp, and a bust at the University of Mons. On 30 June 2020, the 60th anniversary of Congolese independence, King Philippe wrote to President Félix Tshisekedi expressing his "deepest regrets" for the violence and cruelty of the colonial period, although the letter did not name Leopold and many felt it fell short of an apology.

Remembering Leopold's Congo is not about ranking atrocities against each other. It is about counting all the victims, understanding how a system of profit and forced labour could kill on such a scale, and recognising that the people of Central Africa paid the price for wealth that ended up in Europe.
