Heart of Darkness by Joseph Conrad is a novella set in the late 19th century during the height of European colonialism. The story is narrated by a man named Marlow, who recounts his journey up the Congo River in Africa, where he has been hired by a Belgian trading company to retrieve one of its employees, Kurtz, a mysterious and successful ivory trader who has stopped communicating with the company. Marlow becomes obsessed with Kurtz and the rumors surrounding him, hearing that he is both a brilliant man and a morally corrupted figure, worshipped as a god by the local inhabitants.As Marlow ventures deeper into the jungle, he encounters the brutal and dehumanizing effects of colonialism, both on the African land and its people. His journey also becomes a symbolic descent into the darker aspects of human nature. When Marlow finally meets Kurtz, he finds a man who has been consumed by his own power and depravity. Kurtz’s final words, 'The horror! The horror!' reflect his inner torment and recognition of the darkness within himself and the corrupt nature of civilization.The novella explores themes of colonial exploitation, the thin veneer of civilization, and the moral ambiguity inherent in humanity. Marlow’s journey is as much a psychological exploration as a physical one, and *Heart of Darkness* remains a powerful critique of colonialism and the darkness at the core of the human soul.
