Heart of Darkness is a novella written by Joseph Conrad. Before its 1902 publication, it appeared as a three-part series (1899) in Blackwood's Magazine. It is widely regarded as a significant work of English literature and part of the Western canon. The story tells of Charles Marlow, an Englishman who took a foreign assignment from a Belgian trading company as a ferry-boat captain in Africa. Heart of Darkness exposes the dark side of European colonization while exploring the three levels of darkness that the protagonist, Marlow, encounters: the darkness of the Congo wilderness, the darkness of the Europeans' cruel treatment of the natives, and the unfathomable darkness within every human being for committing heinous acts of evil.
