Chinua Achebe was a Nigerian novelist who criticized Joseph Conrad's novella Heart of Darkness as racist. In his 1975 lecture "An Image of Africa: Racism in Conrad's Heart of Darkness," Achebe argued that the novella portrayed Africa and Africans in a negative, stereotypical light. While some saw this portrayal as reflecting the character Marlow's views rather than Conrad's own, Achebe believed Conrad himself held racist beliefs that influenced his writing. Achebe's critique highlighted how colonial-era literature could propagate harmful stereotypes and still impact views of Africa today.
