Nihilism
Nikolai Nadezhdin was probably the first writer to use the word "nihilism" in Russian. He first used it in 1829 by calling scepticism the same as nihilism. And Vasilij Bervi used the same meaning. Russian journalists like Mikhail Katkov and Vissarion Belinsky also used the word. Katkov called nihilism because it rejected all morality. He worried it could cause a revolution. Belinsky used the word in a more neutral way. But the word was still not popular at the time.
