Congo Free State

Diogo Cão traveled around the mouth of the Congo River in 1482,[11] leading Portugal to claim the region as England did with River Victoria. Until the middle of the 19th century, the Congo was at the heart of independent Africa, as European colonialists seldom entered the interior. Along with fierce local resistance, the rainforest, swamps, and attendant malaria, and other diseases such as sleeping sickness made it a difficult environment for Europeans to settle. Western states were at first reluctant to colonize the area in the absence of obvious economic benefits.

Leopold II, King of the Belgians and de facto owner of the Congo Free State from 1885 to 1908

In 1876 Leopold II of Belgium hosted a geographic conference in Brussels, inviting famous explorers, philanthropists, and members of geographic societies to stir up interest in a "humanitarian" endeavor for Europeans to take in central Africa to "improve" and "civilize" the lives of the indigenous peoples.[12] At the conference, Leopold organized the International African Association with the cooperation of European and American explorers and the support of several European governments, and was himself elected chairman. Leopold used the association to promote plans to seize independent central Africa under this philanthropic guise.

Henry Morton Stanley, famous for making contact with British missionary David Livingstone in Africa in 1871, later explored the region during a journey that ended in 1877 and was described in Stanley's 1878 book Through the Dark Continent.[13] Failing to enlist British interest in establishing the Congo region, Stanley took up service with Leopold II, who hired him to help gain a foothold in the region and annex the region for himself.[14]

From August 1879 to June 1884 Stanley was in the Congo basin, where he built a road from the lower Congo up to Stanley Pool and launched steamers on the upper river. While exploring the Congo for Leopold, Stanley set up treaties with the local chiefs and with native leaders.[14] In essence, the documents gave over all rights of their respective pieces of land to King Leopold II. With Stanley's help, Leopold was able to claim a great area along the Congo River, and military posts were established.

Christian de Bonchamps, a French explorer who served Leopold in Katanga, expressed attitudes towards such treaties shared by many Europeans, saying, "The treaties with these little African tyrants, which generally consist of four long pages of which they do not understand a word, and to which they sign a cross in order to have peace and to receive gifts, are really only serious matters for the European powers, in the event of disputes over the territories. They do not concern the black sovereign who signs them for a moment."[15]

Henry Morton Stanley, whose exploration of the Congo region at Leopold's invitation led to the establishment of the Congo Free State under personal sovereignty

Leopold began to create a plan to convince other European powers of the legitimacy of his claim to the region, all the while maintaining the guise that his work was for the benefit of the native peoples under the name of a philanthropic "association".

The king launched a publicity campaign in Britain to distract critics, drawing attention to Portugal's record of slavery, and offering to drive slave traders from the Congo basin. He also secretly told British merchant houses that if he was given formal control of the Congo for this and other humanitarian purposes, he would then give them the same most favored nation (MFN) status Portugal had offered them. At the same time, Leopold promised Bismarck he would not give any one nation special status, and that German traders would be as welcome as any other.

Leopold then offered France the support of the association for French ownership of the entire northern bank of the Congo, and sweetened the deal by proposing that, if his personal wealth proved insufficient to hold the entire Congo, as seemed utterly inevitable, that it should revert to France. On April 23, 1884, the International Association's claim on the southern Congo basin was formally recognized by France on condition that the French got the first option to buy the territory if the association decided to sell. This may also have helped Leopold in gaining recognition for his claim by the other major powers, who thus wanted him to succeed instead of selling his claims to France.[17]

He also enlisted the aid of the United States, sending President Chester A. Arthur carefully edited copies of the cloth-and-trinket treaties Welsh-American explorer Henry Morton Stanley claimed to have negotiated with various local authorities, and proposing that, as an entirely disinterested humanitarian body, the association would administer the Congo for the good of all, handing over power to the locals as soon as they were ready for that responsibility.

King Leopold wanted to have the United States support his plans for the Congo in order to gain support from the European nations. He had help from Henry Shelton Sanford who helped employ Henry Morton Stanley, who became an important asset to Leopold's plan. Henry Sanford swayed Chester A. Arthur by inviting him to stay as his guest at Sanford House hotel on Lake Monroe while he was in Belgium. On November 29, 1883, during his meeting with the President, as Leopold's envoy, he convinced the President that Leopold's agenda was similar to the United States' involvement in Liberia. This satisfied Southern politicians and businessmen, especially John Tyler Morgan. Morgan saw Congo as the same opportunity to send freedmen to Africa so they could contribute to and build the cotton market. Sanford also convinced the people in New York that they were going to abolish slavery and aid travelers and scientists in order to have the public's support. After Henry's actions in convincing President Arthur, the United States was the first country to recognize Congo as a legitimate sovereign state.[18]

Leopold was able to attract scientific and humanitarian backing for the International African Association (French: Association internationale africaine, or AIA), which he formed during a Brussels Geographic Conference of geographic societies, explorers, and dignitaries he hosted in 1876. At the conference, Leopold proposed establishing an international benevolent committee for the propagation of civilization among the peoples of central Africa (the Congo region). The AIA was originally conceived as a multi-national, scientific, and humanitarian assembly, and even invited Gustave Moynier as member of the International Law Institute and president of the International Committee of the Red Cross to attend their 1877 conference. The International Law Institute was supportive of the project under the belief that it was aimed to abolish the Congo Basin slave trade.[19] Nevertheless, the AIA eventually became a development company controlled by Leopold.

After 1879 and the crumbling of the International African Association, Leopold's work was done under the auspices of the "Committee for Studies of the Upper Congo" (French: Comité d'Études du Haut-Congo). The committee, supposedly an international commercial, scientific, and humanitarian group, was in fact made of a group of businessmen who had shares in the Congo, with Leopold holding a large block by proxy. The committee itself eventually disintegrated (but Leopold continued to refer to it and use the defunct organization as a smokescreen for his operations in laying claim to the Congo region).

Determined to look for a colony for himself and inspired by recent reports from central Africa, Leopold began patronizing a number of leading explorers, including Henry Morton Stanley.[21] Leopold established the International African Association, a charitable organization to oversee the exploration and surveying of a territory based around the Congo River, with the stated goal of bringing humanitarian assistance and civilization to the natives. In the Berlin Conference of 1884–85, European leaders officially noted Leopold's control over the 1,000,000 square miles (2,600,000 km²) of the notionally-independent Congo Free State.[22]

To give his African operations a name that could serve for a political entity, Leopold created, between 1879 and 1882, the International Association of the Congo (French: Association internationale du Congo, or AIC) as a new umbrella organization. This organization sought to combine the numerous small territories acquired into one sovereign state and asked for recognition from the European powers. On April 22, 1884, thanks to the successful lobbying of businessman Henry Shelton Sanford at Leopold's request, President Chester A. Arthur of the United States decided that the cessions claimed by Leopold from the local leaders were lawful and recognized the International Association of the Congo's claim on the region, becoming the first country to do so. In 1884, the US Secretary of State said, "The Government of the United States announces its sympathy with and approval of the humane and benevolent purposes of the International Association of the Congo."[23]

In November 1884, Otto von Bismarck convened a 14-nation conference to submit the Congo question to international control and to finalize the colonial partitioning of the African continent. Most major powers (including Austria-Hungary, Belgium, France, Germany, Portugal, Italy, the United Kingdom, Russia, the Ottoman Empire, and the United States) attended the Berlin Conference, and drafted an international code governing the way that European countries should behave as they acquired African territory. The conference officially recognized the International Congo Association, and specified that it should have no connection with Belgium or any other country, but would be under the personal control of King Leopold, i.e., personal union.

It drew specific boundaries and specified that all nations should have access to do business in the Congo with no tariffs. The slave trade would be suppressed. In 1885, Leopold emerged triumphant. France was given 666,000 km² (257,000 sq mi) on the north bank (the modern Congo-Brazzaville and Central African Republic), Portugal 909,000 km² (351,000 sq mi) to the south (modern Angola), and Leopold's personal organisation received the balance: 2,344,000 km² (905,000 sq mi), with about 30 million people. However, it still remained for these territories to be occupied under the conference's "Principle of Effective Occupation".

Following the United States's recognition of Leopold's colony, other Western powers deliberated on the news. Portugal flirted with the French at first, but the British offered to support Portugal's claim to the entire Congo in return for a free trade agreement and to spite their French rivals. Britain was uneasy at French expansion and had a technical claim on the Congo via Lieutenant Cameron's 1873 expedition from Zanzibar to bring home Livingstone's body, but was reluctant to take on yet another expensive, unproductive colony. Bismarck of Germany had vast new holdings in southwest Africa, and had no plans for the Congo, but was happy to see rivals Britain and France excluded from the colony.[2]

In 1885, Leopold's efforts to establish Belgian influence in the Congo Basin were awarded with the État Indépendant du Congo (CFS, Congo Free State). By a resolution passed in the Belgian parliament, Leopold became roi souverain, sovereign king, of the newly formed CFS, over which he enjoyed nearly absolute control. The CFS (today the Democratic Republic of the Congo), a country of over two million square kilometers, became Leopold's personal property, the Domaine Privé. Eventually, the Congo Free State was recognized as a neutral independent sovereignty[14] by various European and North American states.

Leopold could not meet the costs of running the Congo Free State. Desperately, he set in motion a system to maximize revenue. The first change was the introduction of the concept of terres vacantes, "vacant" land, which was any land that did not contain a habitation or a cultivated garden plot. All of this land (i.e., most of the country) was therefore deemed to belong to the state. Servants of the state (namely any men in Leopold's employ) were encouraged to exploit it.

Shortly after the anti-slavery conference he held in Brussels in 1889, Leopold issued a new decree which said that Africans could only sell their harvested products (mostly ivory and rubber) to the state in a large part of the Free State. This law grew out of the earlier decree which had said that all "unoccupied" land belonged to the state. Any ivory or rubber collected from the state-owned land, the reasoning went, must belong to the state; creating a de facto state-controlled monopoly. Suddenly, the only outlet a large share of the local population had for their products was the state, which could set purchase prices and therefore could control the amount of income the Congolese could receive for their work. However, for local elites this system presented new opportunities as the Free State and concession companies paid them with guns to tax their subjects in kind.

Trading companies began to lose out to the free state government, which not only paid no taxes but also collected all the potential income. These companies were outraged by the restrictions on free trade, which the Berlin Act had so carefully protected years before.[35] Their protests against the violation of free trade prompted Leopold to take another, less obvious tack to make money.

A decree in 1892 divided the terres vacantes into a domainal system, which privatized extraction rights over rubber for the state in certain private domains, allowing Leopold to grant vast concessions to private companies. In other areas, private companies could continue to trade but were highly restricted and taxed. The domainal system enforced an in-kind tax on the Free State's Congolese subjects. As essential intermediaries, local rulers forced their men, women and children to collect rubber, ivory and foodstuffs. Depending on the power of local rulers, the Free State paid below rising market prices.[36] In October 1892, Leopold granted concessions to a number of companies. Each company was given a large amount of land in the Congo Free State on which to collect rubber and ivory for sale in Europe. These companies were allowed to detain Africans who did not work hard enough, to police their vast areas as they saw fit and to take all the products of the forest for themselves. In return for their concessions, these companies paid an annual dividend to the Free State. At the height of the rubber boom, from 1901 until 1906, these dividends also filled the royal coffers.[37]

The Free Trade Zone in the Congo was open to entrepreneurs of any European nation, who were allowed to buy 10- and 15-year monopoly leases on anything of value: ivory from a district or the rubber concession, for example. The other zone—almost two-thirds of the Congo—became the Domaine Privé, the exclusive private property of the state.

In 1893, Leopold excised the most readily accessible 259,000 km² (100,000 sq mi) portion of the Free Trade Zone and declared it to be the Domaine de la Couronne, literally, "fief of the crown". Rubber revenue went directly to Leopold who paid the Free State for the high costs of exploitation.[38] The same rules applied as in the Domaine Privé.[33] In 1896 global demand for rubber soared. From that year onwards, the Congolese rubber sector started to generate vast sums of money at an immense cost for the local population.[39]

Cecil Rhodes attempted to expand the territory of the British South Africa Company northward into the Congo basin, presenting a problem for Leopold II.

Early in Leopold's rule, the second problem—the British South Africa Company's expansion into the southern Congo Basin—was addressed. The distant Yeke Kingdom, in Katanga on the upper Lualaba River, had signed no treaties, was known to be rich in copper and thought to have much gold from its slave-trading activities. Its powerful mwami (King), Msiri, had already rejected a treaty brought by Alfred Sharpe on behalf of Cecil Rhodes. In 1891 a Free State expedition extracted a letter from Msiri agreeing to their agents coming to Katanga and later that year Leopold II sent the well-armed Stairs Expedition, led by the Canadian mercenary William Grant Stairs, to take possession of Katanga one way or another.[40]

Msiri tried to play the Free State off against Rhodes and when negotiations bogged down, Stairs flew the Free State flag anyway and gave Msiri an ultimatum. Instead, Msiri decamped to another stockade. Stairs sent a force to capture him but Msiri stood his ground, whereupon Captain Omer Bodson shot Msiri dead and was fatally wounded in the resulting fight.[40] The expedition cut off Msiri's head and put it on a pole, as he had often done to his enemies. This was to impress upon the locals that Msiri's rule had really ended, after which the successor chief recognized by Stairs signed the treaty.[41]

In the short term, the third problem, that of the African and Arab slavers like Zanzibari/Swahili strongman Tippu Tip (nom de guerre)—his real name was Hamad bin Muhammad bin Juma bin Rajab el Murjebi—was temporarily solved. Initially the authority of the Congo Free State was relatively weak in the eastern regions of the Congo.

Slave trader Rumaliza, 1900

In early 1887, Henry Morton Stanley arrived in Zanzibar and proposed that Tippu Tip be made governor (wali) of the Stanley Falls District. Both Leopold II and Barghash bin Said agreed and on February 24, 1887, Tippu Tip accepted.[42]

In the longer term this alliance was indefensible at home and abroad. Leopold II was heavily criticized by the European public opinion for his dealings with Tippu Tip. In Belgium, the Belgian Anti-Slavery Society was founded in 1888, mainly by Catholic intellectuals led by Count Hippolyte d'Ursel, aimed at abolishing the Arab slave trade. Furthermore, Tippu Tip and Leopold were commercial rivals. Every person that Tippu Tip hunted down and put into chattel slavery and every pound of ivory he exported to Zanzibar was a loss to Leopold II. This, and Leopold's humanitarian pledges to the Berlin Conference to end slavery, meant war was inevitable.

Open warfare broke out in late November 1892. Both sides fought by proxy, arming and leading the populations of the upper Congo forests in conflict. By early 1894 the Zanzibari/Swahili slavers were defeated in the eastern Congo region and the Congo Arab war came to an end.

Francis Dhanis, ca. 1900

In 1894, King Leopold II signed a treaty with the United Kingdom which conceded a strip of land on the Free State's eastern border in exchange for the Lado Enclave, which provided access to the navigable Nile and extended the Free State's sphere of influence northwards into Sudan. After rubber profits soared in 1895, Leopold ordered the organization of an expedition into the Lado Enclave, which had been overrun by Mahdist rebels since the outbreak of the Mahdist War in 1881.[43] The expedition was composed of two columns: the first, under Belgian war hero Baron Dhanis, consisted of a sizable force, numbering around three-thousand, and was to strike north through the jungle and attack the rebels at their base at Rejaf. The second, a much smaller force of only eight-hundred, was led by Louis-Napoléon Chaltin and took the main road towards Rejaf. Both expeditions set out in December 1896.[44]

Although Leopold II had initially planned for the expedition to carry on much farther than the Lado Enclave, hoping indeed to take Fashoda and then Khartoum, Dhanis' column mutinied in February 1897, resulting in the death of several Belgian officers and the loss of his entire force.[45] Nonetheless, Chaltin continued his advance, and on 17 February 1897, his outnumbered forces defeated the rebels in the Battle of Rejaf, securing the Lado Enclave as a Belgian territory until Leopold's death in 1909.[46] Leopold's conquest of the Lado Enclave met with approval from the British government, at least initially, which welcomed any aid in their ongoing war with Mahdist Sudan. But frequent raids outside of Lado territory by Belgian Congolese forces based in Rejaf caused alarm and suspicion among British and French officials wary of Leopold's imperial ambitions.[47] In 1910, following the Belgian annexation of the Congo Free State as the Belgian Congo in 1908 and the death of the Belgian King in December 1909, British authorities reclaimed the Lado Enclave as per the Anglo-Congolese treaty signed in 1894, and added the territory to Anglo-Egyptian Sudan.[48]

Mutilated Congolese children, image from King Leopold's Soliloquy, Mark Twain’s political satire, where the aging king complains that the incorruptible camera was the only witness he had encountered in his long experience that he could not bribe. The book was illustrated with photographs by John Hobbis Harris.

Failure to meet the rubber collection quotas was punishable by death. Meanwhile, the Force Publique were required to provide the hand of their victims as proof when they had shot and killed someone, as it was believed that they would otherwise use the munitions (imported from Europe at considerable cost) for hunting.[52] As a consequence, the rubber quotas were in part paid off in chopped-off hands. Sometimes the hands were collected by the soldiers of the Force Publique, sometimes by the villages themselves. There were even small wars where villages attacked neighboring villages to gather hands, since their rubber quotas were too unrealistic to fill. A Catholic priest quotes a man, Tswambe, speaking of the hated state official Léon Fiévez, who ran a district along the river 500 kilometres (300 mi) north of Stanley Pool:

All blacks saw this man as the devil of the Equator ... From all the bodies killed in the field, you had to cut off the hands. He wanted to see the number of hands cut off by each soldier, who had to bring them in baskets ... A village which refused to provide rubber would be completely swept clean. As a young man, I saw [Fiévez's] soldier Molili, then guarding the village of Boyeka, take a net, put ten arrested natives in it, attach big stones to the net, and make it tumble into the river ... Rubber causes these torments; that's why we no longer want to hear its name spoken. Soldiers made young men kill or rape their own mothers and sisters.[54]

One junior officer described a raid to punish a village that had protested. The officer in command "ordered us to cut off the heads of the men and hang them on the village palisades ... and to hang the women and the children on the palisade in the form of a cross".[55] After seeing a Congolese person killed for the first time, a Danish missionary wrote, "The soldier said 'Don't take this to heart so much. They kill us if we don't bring the rubber. The Commissioner has promised us if we have plenty of hands he will shorten our service.'"[56] In Forbath's words:

The baskets of severed hands, set down at the feet of the European post commanders, became the symbol of the Congo Free State. ... The collection of hands became an end in itself. Force Publique soldiers brought them to the stations in place of rubber; they even went out to harvest them instead of rubber ... They became a sort of currency. They came to be used to make up for shortfalls in rubber quotas, to replace ... the people who were demanded for the forced labour gangs; and the Force Publique soldiers were paid their bonuses on the basis of how many hands they collected.

In theory, each right hand proved a killing. In practice, to save ammunition soldiers sometimes "cheated" by simply cutting off the hand and leaving the victim to live or die. More than a few survivors later said that they had lived through a massacre by acting dead, not moving even when their hands were severed, and waiting till the soldiers left before seeking help. In some instances a soldier could shorten his service term by bringing more hands than the other soldiers, which led to widespread mutilations and dismemberment.

A reduction of the population of the Congo is noted by all who have compared the country at the beginning of Leopold's control with the beginning of Belgian state rule in 1908, but estimates of the death toll vary considerably. Estimates of some contemporary observers suggest that the population decreased by half during this period. According to Edmund D. Morel, the Congo Free State counted "20 million souls".[57] Hence, Mark Twain mentioned the number of ten million deaths.[58] According to Irish diplomat Roger Casement, this depopulation had four main causes: "indiscriminate war", starvation, reduction of births, and disease.[59] Sleeping sickness was also a major cause of fatality at the time. Opponents of Leopold's rule stated, however, that the administration itself was to be considered responsible for the spreading of the epidemic.[60]

In the absence of a census providing even an initial idea of the size of population of the region at the inception of the Congo Free State (the first was taken in 1924),[61] it is impossible to quantify population changes in the period. Despite this, Forbath more recently claimed the loss was at least five million.[62] Adam Hochschild and Jan Vansina use the number 10 million. Hochschild cites several recent independent lines of investigation, by anthropologist Jan Vansina and others, that examine local sources (police records, religious records, oral traditions, genealogies, personal diaries), which generally agree with the assessment of the 1919 Belgian government commission: roughly half the population perished during the Free State period. Since the first official census by the Belgian authorities in 1924 put the population at about 10 million, these various approaches suggest a rough estimate of a total of 10 million dead.[63] Jan Vansina returned to the issue of quantifying the total population decline, and revised his earlier position, he concluded that the Kuba population (one of the many Congolese populations) was rising during the first two decades of Leopold II's rule, and declined with 25 percent from 1900 to 1919, mainly due to sickness.[64][65][66] Others argued a decrease of 20 percent over the first forty years of colonial rule (up to the census of 1924).[67] According to the Congolese historian Isidore Ndaywel è Nziem 13 million died.[68] To put these population changes in context, sourced references state that in 1900 Africa as a whole had between 90 million[69] and 133 million people.[70] However, no verifiable records exist. Louis and Stengers state that population figures at the start of Leopold's control are only "wild guesses", while calling E. D. Morel's attempt and others at coming to a figure for population losses "but figments of the imagination".[71] However, authors that point out the lack of reliable demographic data are questioned by others calling the former minimalists and agnosticists,[72] proving that these questions remain the object of heated debate.

Roger Casement

E.D. Morel

Joseph Conrad’s novel Heart of Darkness, originally published in 1899 as a three-part series in Blackwood's Magazine, inspired by his service as a captain on a steamer on the Congo 12 years before, sparked an organized international opposition to Leopold's exploitational activities. In 1900, Edmund Dene Morel, a part-time journalist and head of trade with Congo for the Liverpool shipping firm Elder Dempster, noticed that ships that brought vast loads of rubber from the Congo only ever returned there loaded with guns and ammunition for the Force Publique.[76] Morel became a journalist and then a publisher, attempting to discredit Leopold's regime. In 1902, Morel retired from his position at Elder Dempster to focus on campaigning. He founded his own magazine, The West African Mail, and conducted speaking tours in Britain.

Increasing public outcry over the atrocities in the CFS moved the British government to launch an official investigation. In 1903, Morel and those who agreed with him in the House of Commons succeeded in passing a resolution calling on the British government to conduct an inquiry into alleged violations of the Berlin Agreement. Roger Casement, then the British Consul at Boma (at the mouth of the Congo River), was sent to the Congo Free State to investigate. Reporting back to the Foreign Office in 1900, Casement wrote:

The root of the evil lies in the fact that the government of the Congo is above all a commercial trust, that everything else is orientated towards commercial gain ...

E. D. Morel was introduced to Roger Casement by their mutual friend Herbert Ward[77] just before the publication of Casement's 1904 detailed eyewitness report—known as the Casement Report—in 1904 and realized that he had found the ally he had sought. Casement convinced Morel to establish an organisation for dealing specifically with the Congo question, the Congo Reform Association. With Casement's and Dr. Guinness's assistance, he set up and ran the Congo Reform Association, which worked to end Leopold's control of the Congo Free State. Branches of the association were established as far away as the United States. The Congo Reform movement's members included Sir Arthur Conan Doyle, Mark Twain, Joseph Conrad, Booker T. Washington, and Bertrand Russell.

The mass deaths in the Congo Free State became a cause célèbre in the last years of the 19th century. The Congo reform movement led a vigorous international movement against the maltreatment of the Congolese population.[78][79] The British Parliament demanded a meeting of the 14 signatory powers to review the 1885 Berlin Agreement. The Belgian Parliament, pushed by Emile Vandervelde and other critics of the king's Congolese policy, forced Leopold to set up an independent commission of inquiry, and despite the king's efforts, in 1905 it confirmed Casement's report.

One of the main ways England was involved in ending Leopold II of Belgium’s rule in the Congo, was by making Belgium, as a whole, more aware of the brutality present in the Congo. E. D. Morel was one of the key activists of England for a Congo free from Belgium rule. Once the U.S became aware of the occurrences in the Congo, Morel began the Congo Reform Association. One of the methods Morel used to make the world more aware of the atrocities in the Congo during Leopold’s rule was through the press. Articles were published in both magazines and newspapers in order to make the people of these powerful countries, such as the U.S and England, more aware of what truly was being done in this part of Africa. With this newfound unwanted publicity, the Belgium government was pressured in assuming control of the Congo from Leopold.[80]

Individuals such as George Washington Williams also had a significant impact on the Congo Free State propaganda war. In his famous letter, "An Open Letter to His Serene Majesty Léopold II, King of the Belgians and Sovereign of the Independent State of Congo", sent on July 18, 1890, Williams described in great detail the crimes committed against the residents of the Congo and their overall mistreatment. This letter was a key factor in the propaganda struggle over conditions in the Congo.[81]

In the aftermath of the 1998 publication of King Leopold's Ghost by Adam Hochschild, where he had written "the killing in the Congo was of genocidal proportions", but "it was not strictly speaking a genocide",[87] The Guardian reported that the Royal Museum for Central Africa in Brussels would finance an investigation into some of the claims made by Hochschild. An investigatory panel announced in 2002, likely to be headed by Professor Jean-Luc Vellut, was scheduled to report its findings in 2004.[79] Robert G. Weisbord stated in the 2003 Journal of Genocide Research that attempting to eliminate a portion of the population is enough to qualify as genocide under the UN convention. In the case of the Congo Free State, the unbearable conditions would qualify as a genocide.[87]

In the aftermath of the report, an exhibition was held at the Royal Museum for Central Africa entitled The Memory of Congo. Critics, including Hochschild, claimed that there were "distortions and evasions" in the exhibition and stated: "The exhibit deals with this question in a wall panel misleadingly headed 'Genocide in the Congo?' This is a red herring, for no reputable historian of the Congo has made charges of genocide; a forced labor system, although it may be equally deadly, is different."[88]

An early day motion presented to the British Parliament in 2006 described "the tragedy of King Leopold's regime" as genocide and called for an apology from the Belgian government. It received the signature of 48 members of parliament.[89]
