Russian Nihilism is a variant of Nihilism. Russian Nihilists did not argue that there's nothing worth following, but rather that the status-quo values in Russia is oppressive and meaningless, thus the values must be destroyed and be replaced with new ones. Sergey Nechayev who was the figurehead of Russian Nihilist Movement, in instance, argued that anarchists must abolish humanity (as a value), family, love, names and ect.
The movement had shared many left-wing ideas such as that from Socialism, civically variable, agrarian, and revolutionary anti-monarchist movement from the Russian Empire in the late 19th century. It was primarily inspired by the thought of the Young Hegelians and Russian anarchist Mikhail Bakunin. Ideas varied wildly between theoreticians. Some supported Anarchism ( Bakunin), some supported Republicanism ( Chernyshevsky), and some supported what was perceived as Totalitarianism ( Nechayev). One thing these theorists all shared was an opposition to traditional values, monarchism, and religion. Another thing to note is that some nihilists were greatly influenced by Russian antinihilist literature such as Ivan Turgenevs "fathers and sons" or Fyodor Dostoevskys work and aspired to be like the nihilist characters in those stories.
