The article is devoted to the views of Eurasians of the Ukrainian issue. That they were deeply interested in is not surprising. As Z. Brzezinski wrote, “Russia without Ukraine ceases to be a Eurasian Empire”. However, according to the Eurasians' doctrine, this Empire was Central. In order to understand the views of Eurasians of the Ukrainian issue, the author had to analyze N.S. Trubetskoy's articles, his disagreement with the famous Ukrainian historian D.I. Doroshenko. They argued about the mutual relationship of the Ukrainian and Russian languages and culture, but agreed on the main point: the fear of coming to power in Ukraine political extremists, «narrow political chauvinists». According to the author, some of the statements of the parties to this dispute are difficult to accept, in particular, Prince clearly underestimates the political moment, while the Ukrainian historian idealizes the situation in Ukraine. Special attention is paid to the attitude to the Ukrainian issueexpressed by the historian G.V. Vernadsky. The author believes that his views can be understood only if viewed in tandem with the views of his famous father - V.I. Vernadsky. They both loved Ukraine and understood the complexity of the Ukrainian issue, focusing on the difficult fate of a number of Ukrainian regions and, above all, of the Western Ukraine and the Carpathian region. To understand the standpoints of the historian, the unpublished article “Prince Trubetskoy and the Ukrainian Issue” is of great importance, which for the first time in historiography is exposed to thorough analysis. An important addition to this article and other statements on the Ukrainian issue of Eurasians is a correspondence between them. The analysis enables the author to conclude that already in the mid 30-s the Eurasians paid attention to the situation of the Russian population in Ukraine and, in fact, already predicted the current humanitarian disaster in the Eastern districts. After analyzing the views of “the last Eurasian” L.N. Gumilev, the author recognized the great interest of his ethnological observations, but he felt that like the N.S. Trubetskoy, he underestimated the political component of the historical process.
