The contexts of Czech literature are related to the crisis and revolutionary situation which gradually built up towards the end of the 19th century and reached its peak in the years of World War I and during the attempts at the world revolution. This was manifested by a certain dichotomy of Czech literature after 1918 when Czechoslovakia came into existence as a relatively large state and a strong parliamentary democracy amidst more or less authoritarian countries, a state with the first-rate Czechoslovak legions tested in the battles of World War I, with strong industry and agriculture which had been the nucleus of Austria-Hungary in the past. On the one hand, there was a majority and influential left, on the other were conservative groups often connected with Catholic Church, and in the middle — liberal currents linked with the official policy of the so-called Prague Castle represented by the first president T. G. Masaryk (e g. Karel Čapek). Nevertheless, Czech literature as a whole helped create national and state consciousness, with the currents differing from each other only in their preference for traditions and political and economic systems. The problems of the new state were, of course, not only social, but also national, ethnic and religious and were also reflected in the international arena. Unlike in the other Central European countries, Czech literature exhibited radical leftist tendencies which were realised in the Czech modernist avant-garde, the apex of which was Czech poetism and surrealism (with the corresponding current in Slovakia) and their authors, such as Vítězslav Nezval, František Halas, Josef Hora, Jaroslav Seifert (1984 Nobel Prize winner), and Konstantin Biebl etc., but also the Catholic current which was very impressive from the artistic point of view (Jakub Deml, Jaroslav Durych, Jan Zahradníiek, Jan Čep and others). Both of these tendencies were surprisingly and paradoxically linked with each other, as were their representatives. The drama and the novel (the Brothers Čapek, and Vladislav Vaniura etc.) occupied a prominent place alongside poetry. What shows the mutual relationship between “the building of the state“ (the title of a very important book by the famous Czech journalist and politician Ferdinand Peroutka) and Czech literature is the fact that between 1918 and 1938 Czech literature reached a world level for the first time in modern history. The author defends the thesis that Czech literature connected with the rise of the independent Czechoslovak state regardless of all these problems and idealistic constructs (“Czechoslovakism”), created a specific, original model of the co-existence of various currents of thought and of the relationships between culture in its widest sense and practical politics. This enabled radical artistic innovations anticipating the evolutionary tendencies of world literature (surrealism, anti-utopia/dystopia, baroquizing prose, and experimental novel).
