Anarchism in Ukraine has its roots in the democratic and egalitarian organization of the Zaporozhian Cossacks, who inhabited the region up until the 18th century. Philosophical anarchism first emerged from the radical movement during the Ukrainian national revival, finding a literary expression in the works of Mykhailo Drahomanov, who was himself inspired by the libertarian socialism of Pierre-Joseph Proudhon. The spread of populist ideas by the Narodniks also lay the groundwork for the adoption of anarchism by Ukraine's working classes, gaining notable circulation in the Jewish communities of the Pale of Settlement.
