Nietzsche's claim that belief in the Christian God had collapsed in modern Europe, taking the old foundation of morality with it.
See it on the Philosophy map →The idea
Idea: modern Europeans no longer truly believe in God, and have not faced what that means. In The Gay Science (1882) a madman with a lantern cries in the marketplace, 'God is dead... and we have killed him.' Science and modern life had eroded faith. Nietzsche's fear was nihilism: values with nothing underneath. It describes a culture; it is not a proof that God does not exist. Main objection: belief remains widespread, and morality may rest on grounds other than God.
Why it matters
It framed the 20th century's question of where values come from without religion, the starting point for existentialism and much modern thought.
Think of it like
Like a building after the anchor tenant leaves: it still stands and runs for a while, but what paid for it is gone.
Where it comes from
The Gay Science (1882), sections 108 and 125, and Thus Spoke Zarathustra (1883–85). Hegel and the poet Heine had used the phrase earlier, in other senses.
Still debated
Whether Nietzsche mourned or welcomed the death of God is debated; the madman's speech sounds more like alarm than triumph.

Connections (3)
▸Friedrich Nietzsche proclaimed "God is dead"Well documented
The connection
Nietzsche put the phrase in the mouth of a madman who runs into a marketplace with a lantern in broad daylight, telling unbelievers they have killed God without grasping the consequences. His point was cultural: once faith fades, the Christian morality built on it loses its foundation, and Europe faces nihilism.
When and how
The Gay Science, section 125, published in 1882, when Nietzsche, retired from his Basel professorship by ill health, was living between Switzerland and Italy.
How we know
The passage is in the published text, and he repeats the theme in Thus Spoke Zarathustra (1883–85).
Debates and open questions
Whether he meant a warning, a celebration or a plain diagnosis is debated; the madman says the news 'has not yet reached' people.
▸"God is dead" raised Does life have meaning?Mostly agreed
The connection
If God no longer gives life a purpose, the question of meaning becomes urgent and open. Nietzsche saw the danger of nihilism, the sense that nothing matters, and asked what could replace religion. His challenge set the terms for 20th-century answers, from creating our own values to Camus' defiance of the absurd.
When and how
Nietzsche raised it in the 1880s; it was pressed hardest in Europe after the two world wars, by Sartre, Camus and others in the 1940s.
How sure are we?
Nietzsche's notebooks discuss nihilism directly, and later writers such as Camus, in The Rebel (1951), discuss his diagnosis at length.
Debates and open questions
Whether meaning really depends on God is disputed: Epicureans, Buddhists and Confucians found purpose without a creator God, and many religious thinkers reject Nietzsche's premise.
▸"God is dead" set the stage for ExistentialismMostly agreed
The connection
Nietzsche's claim left humans with no given purpose or moral rulebook. Existentialists accepted this starting point and drew a demanding conclusion: since no God defines human nature, each person must define it through choice. Sartre wrote that without God we are 'forlorn', with no excuses, entirely responsible for ourselves.
When and how
The line runs from Nietzsche's books of the 1880s to Paris in the 1940s, especially Sartre's lecture 'Existentialism Is a Humanism' (1945).
How sure are we?
Sartre's lecture argues directly from God's absence; Heidegger lectured on Nietzsche for years, and Camus' The Rebel (1951) discusses him at length.
Debates and open questions
Not all existentialists were atheists: Kierkegaard, Gabriel Marcel and Karl Jaspers were religious, so the 'death of God' is one root among several.
