King Leopold ' s Ghost King Leopold ' s Ghost ( 1998 ) is a best - selling popular history book by Adam Hochschild that explores the exploitation of the Congo Free State by King Leopold II of Belgium between 1885 and 1908 , as well as the atrocities that were committed during that period . The book aims to increase public awareness of crimes committed by European colonial rulers in Africa . It was refused by nine of the ten U . S . publishing houses to which an outline was submitted , but became an unexpected bestseller and won the prestigious Mark Lynton History Prize for literary style . It also won the 1999 Duff Cooper Prize . By 2013 , more than 600 , 000 copies were in print in a dozen languages . The book is the basis of a 2006 documentary film of the same name , directed by Pippa Scott and narrated by Don Cheadle . Title . The title is adopted from the 1914 poem " The Congo " , by Illinois poet Vachel Lindsay . Condemning Leopold ' s actions , Lindsay wrote : Content . The story chronicles the efforts of King Leopold II of Belgium to make the Congo into a colonial empire . With a complex scheme of political intrigue , corruption and propaganda , he wins the assistance of one of the best - known explorers of the time , Henry Morton Stanley , as well as that of public opinion and of powerful states . Through the Berlin Conference and other diplomatic efforts , he finally obtains international recognition for his colony . He then establishes a system of forced labour that keeps the people of the Congo basin in a condition of slavery . The book places King Leopold among the great tyrants of history . The death toll in the Congo under his regime is hard to pin down , both because accurate records were not kept and because many of the existing records were deliberately destroyed by Leopold shortly before the government of Belgium took the Congo out of his hands . Although Wm . Roger Louis and Jean Stengers characterize the earliest population and mortality estimates as " wild guesses " , Hochschild cites many subsequent lines of inquiry that conclude that the early official estimates were essentially correct : roughly half the population of the Congo perished during the Free State period . Since the census taken by the Belgian government ( after acquiring the Congo from Leopold ) found some 10 million inhabitants , Hochshild concludes that roughly 10 million perished , though the precise number can never be known . Hochschild profiles several people who helped make the world aware of the reality of the Congo Free State , including : Hochschild devotes a chapter to Joseph Conrad , the famous Anglo - Polish writer , who captained a steamer on the Congo River in the first years of Belgian colonization . Hochschild observes that Conrad ' s novel " Heart of Darkness " , despite its unspecific setting , gives a realistic picture of the Congo Free State . Its main character , Kurtz , was inspired by real state functionaries in the Congo , notably Leon Rom . While " Heart of Darkness " is probably the most reprinted and studied short novel of the 20th century , its psychological and moral truths have largely overshadowed the literal truth behind the story . Hochschild finds four likely models for Kurtz : men who , like Kurtz , boasted of cutting off the heads of African rebels and sometimes displayed them . Scholarship . Hochschild cites the research of several historians , many of them Belgian . He refers especially to Jules Marchal , formerly a Belgian colonial civil servant and diplomat who ( as Hochschild describes ) spent twenty years trying to break Belgian silence about the massacres . The documentation was not easy to come by ; the furnaces of the palace in Brussels are said to have spent more than a week burning incriminating papers before Leopold turned over his private Congo to the Belgian nation . For many years Belgian authorities prevented access to what remained of the archives , notably the accounts given by Congolese to the King ' s Commission . Although few Africa scholars outside of Belgium seriously question that large numbers died in Leopold ’ s Congo , the subject remains a touchy one in Belgium itself . The country ’ s Royal Museum for Central Africa , founded by Leopold II , mounted a special exhibition in 2005 about the colonial Congo ; in an article in the " New York Review of Books " , Hochschild accused the museum of distortion and evasion . Also in 2005 , the American and British publishers of " King Leopold ’ s Ghost " reissued the book with a new “ Afterword ” by Hochschild in which he talks about the reactions to the book , the death toll , and events in the Congo since its publication . Reception . Hochschild has been praised by critics for his narrative . However , he acknowledges that most of the facts illustrated in the book were already known ( although appearing in works in several languages ) . The book was praised by scholars of Africa such as Prof . Robert Harms of Yale University and by the South African Nobel laureate Nadine Gordimer . Belgian historian Jules Marchal called the book " a masterpiece , without even one error about the historical deeds related . " Several other Belgian experts on the period , such as anthropologist Jan Vansina , have also voiced support for Hochschild . Isidore Ndaywel è Nziem , a Congolese scholar whose " Histoire générale du Congo " was published the same year as " King Leopold ' s Ghost " , estimated the death toll in the Free State era and its aftermath at roughly 13 million , a higher figure than the various estimates cited by Hochschild . While Hochschild has said that his intention was to tell the story in " a way that brings characters alive , that brings out the moral dimension , that lays bare a great crime and a great crusade " , he was criticised for his overly moralistic dimension and many deplored his comparison of Leopold with Hitler and Stalin . The Belgian historian Jean Stengers , whose works are cited in " King Leopold ' s Ghost " , argued in a newspaper article that Hochschild ' s moral judgements were " not justified in respect to the time and place " and that his conclusions about the scale of the mass murder where based on incomplete statistics . He argued that , in Hochschild ' s book , historical objectivity was affected by the desire to attract a wide public . Hochschild replied to Stengers ' criticism , accusing him of not accepting the implications of his own research , arguing that while Stengers was " a meticulous and talented scholar " , he was affected by colonialist bias . Hochschild points out that the estimates about the reduction of the population of the Congo reported in his book are taken in part from Stengers ' writings . . Hochschild was also criticized by Barbara Emerson , the author of a notable biography of Leopold , who described his book as " a very shoddy piece of work " and declared that " Leopold did not start a genocide . He was greedy for money and chose not to interest himself when things got out of control . " Hochschild does not use the word genocide , but describes how the mass deaths happened as a result of the forced labor system instituted at Leopold ' s direction .
