The paper The Poetry of Rudolf Dilong in the Service of the National Idea is a selective probe into the issue of the representation of national themes in the poetry of the Catholic Modern poet Rudolf Dilong (1905-1986). The whole spectrum of national and nationalist art is characterized by a particular lexis (rhetoric, pathetic words, topography, etc.) and national or regional symbols. Nation-oriented verses in a „softer" form can already be found in Dilong's first rural-vitalist and naive-sentimental collections, primarily through the relation to his native region. The construction of a national myth involved the celebration of the nation's rich history and its territorial integrity (especially tradition of Nitra, Great Moravia, Cyril and Methodius, most concentratedly expressed in the collection Roky pod slnkom, 1933), the glorification of distinguished and state-forming figures (from Pribina to J. Tiso), the thematization of speech (also through the codifiers of language A. Bernolák and Ľ. Štúr), ethnicity (the motif of blood and lineage, especially in the collection Oslava rodu, 1943), the characteristic features of the national community (the myth of the peaceful and plebeian nation), etc. The poetically constructed grand history of the nation was also supported by combining historical facts with pseudo-facts, stereotypes and myths, blurring the boundary between them and artificially emphasising the antiquity of the Slovaks. The escalating radicalisation before the Second World War was also manifested in the „hard", vulgar forms of nationalist poetry represented by the collection Gardisti, na stráž! (1939). In line with the folk mythology, he emphasized the importance of the leadership personality (A. Hlinka, J. Tiso) and „martyr" sacrifice in the life of the nation (Anton Kopal). National issues were also raised through themes such as the day of the establishment of the Slovak state on 14 March, the so-called Little War, the secession of Slovak territory in favour of Poland, the celebration of the paramilitary organisation HG, etc. The justification of radicalisation was made possible by the reduction of a complex multidimensional reality to a schematic battle of opposing forces, the evocation of an ever-present sense of threat in the face of the vague unveiling of the enemy.
