This paper focuses on selected historiography concepts of the soviet historian and ethnologist L. N. Gumilev (1912–1992). The main aim is to present Gumilev's revision of the Kulikovo battle (1380). Paper is based on his two articles published in 1980 on the occasion of the 600th anniversary of the event. Primary sources are supplemented by Gumilev's correspondence deposited in Prague and St. Petersburg. Paper clarifies alleged Eurasianist aspects of Gumilev's articles and consequences of their ambivalent reception in the intellectual milieu of Russian nationalists.
