The aim of this work is to examine Byron’s impact on Russian romanticism by comparative analysis of the novel Eugene Onegin and the poem Childe Harold's Pilmarage. The characteristics to be taken into consideration are the introduction of Byronic hero and its implementation into the Russian context. The primary similarity between English and Russian romanticism is Byronic hero who possesses a pessimistic worldview and encourages the rejection of traditions, alienation, and excessive enjoyment of freedom. Another important link between Russian and English romanticism is dandyism, a movement due to which men’s fashion flourished and clothing became a means of expressing the spirit. The paper concludes that there are common prototypes on which the creation of both heroes was based, so Onegin and Harold are a Byronic combination of heroes characteristic of the Romantic period. However, Onegin, unlike Harold, is not in an exotic setting, but in a simple Russian village and his main characteristic is dandy rebellion, while Harold is a noble soul that suffers because of the cruel world. And finally, by analyzing the elements of dandyism in the poem and the novel, it has been concluded that both characters possessed elements of dandyism.
