Oryol and they ran a printing house in Smolensk, which printed the group's manifesto and revolutionary brochures. Narodnaya Volya favoured agitation among urban workers and intellectuals, rather than spreading propaganda among the peasants (a tactic adopted by the other offshoot of 'Land and Liberty', the 'Black Repartition' group). Narodnaya Volya also endorsed political terrorism as a tactic and in 1881, they assassinated Tsar Alexander II. Natanson was not directly involved in any terrorist act. In April 1894, Narodnaya Volya was liquidated by the police administrator Sergei Zubatov, and its leaders were arrested. In exile in Yakutsk, he married Varvara Alexandrova.

Natanson remained an active revolutionary even in Siberian exile, maintaining the party treasury and coordinating various organisational tasks. Upon returning from exile, he lived in Baku, where he worked as an accountant in the city government. In 1904 he emigrated to Switzerland, where he met with Vladimir Ilyich Ulyanov.
