The essay analyses Milan Rastislav Štefánik's attitudes towards the political ideology movement of Hlasism, named after the Hlas magazine (1898–1904). The author compares memories of a significant literary historian and linguist Jozef Škultéty on M. R. Štefánik's standpoints as a student, scholar, soldier and politician with his activities and journalism. Škultéty, one of the leading representatives of a conservative nationalist centre in Martin, contradicted Štefánik's identification with the Hlasists; however, he completely disregarded his publishing activities between 1902 and 1903 and his lecturing and organizing activities in Detvan. In view of this, Štefánik's articles and reviews in the Hlas and Čas magazines such as Vystěhovalectví na Slovensku, Česko-slovenská jednota národní, Slovenská žurnalistika seem essential. Štefánik's undisputable support of the Hlasist movement can be proved by the fact that he took active part in propagating the Hlasist ideas in Detvan, an association of Slovak students in Prague, participated in editorial work connected with publishing a Hlas supplement (Umelecký Hlas) and distribution of the magazine. In his articles, Štefánik sharply criticized the Martin centre and its policy, while professing ideas of realism and principles propagated by the ideological leader of the Hlasists Vavro Šrobár with whom he kept friendship and exchanged letters even after his move abroad. Why Štefánik's affiliation with the Hlasists is disputed or even utterly rejected remains a question with such a clear demonstration of Štefánik's support to the Hlasist movement. In addition to political intentions spurred by an autonomist movement in the inter-war Slovakia, Štefánik's concern with natural sciences may offer a partial explanation. After his relatively early moving abroad, his contacts with the domestic circles weakened and he no longer concentrated on journalism concerned with the Slovaks' social issues.
