Heart of Darkness, novella by Joseph Conrad that was first published in 1899 in Blackwood's Edinburgh Magazine and then in Conrad's Youth: and Two Other Stories (1902).

Heart of Darkness examines the horrors of Western colonialism, depicting it as a phenomenon that tarnishes not only the lands and peoples it exploits but also those in the West who advance it.

Although garnering an initially lacklustre reception, Conrad's semiautobiographical tale has gone on to become one of the most widely analyzed works of English literature.

Critics have not always treated Heart of Darkness favourably, rebuking its dehumanizing representation of colonized peoples and its dismissive treatment of women.

Nonetheless, Heart of Darkness has endured, and today it stands as a Modernist masterpiece directly engaged with postcolonial realities.
