The Russian nihilist movement was a philosophical, cultural, and revolutionary movement in the Russian Empire during the late 19th and early 20th centuries, from which the broader philosophy of originated. In Russian, the word нигилизм (нигилизм; meaning 'nihilism', ) came to represent the movement's unremitting attacks on morality, religion, and traditional society. Even as it was yet unnamed, the movement arose from a generation of young radicals disillusioned with the social reformers of the past, and from a growing divide between the old aristocratic intellectuals and the new radical intelligentsia.
Russian anarchist Peter Kropotkin, as stated in the Encyclopædia Britannica, "defined nihilism as the symbol of struggle against all forms of tyranny, hypocrisy, and artificiality and for individual freedom." As only an early form of nihilist philosophy, Russian nihilism saw all the morality, philosophy, religion, aesthetics, and social institutions which were in place as worthless and meaningless but did not necessarily see meaninglessness in all ethics, knowledge, and human life. It did however, incorporate theories of hard determinism, atheism, materialism, positivism, and egoism in an aim to assimilate and distinctively recontextualize core elements of the Age of Enlightenment into Russia while dropping the Westernizer approach of the previous generation. Russian nihilism developed an atmosphere of extreme moral scepticism, at times praising outright selfishness and championing those who held themselves exempt from all moral authority. In its most complete forms it also denied the possibility of common ideals, instead favouring a relativist and individualistic outlook. Nihilists predictably fell into conflict with the Russian Orthodox religious authorities, as well as with prevailing family structures and the Tsarist autocracy.
Although most commonly associated with revolutionary activism, most nihilists were in fact not political and instead discarded politics as an outdated stage of humanity.
