How did the creation of Czechoslovakia in 1918 affect Czech literature and drama?

The establishment of an independent Czechoslovak state in 1918 served as a catalyst for a flourishing period in Czech literature and drama.1

In the realm of drama, the new era saw the rise of idealistic and satirical works, most notably by Karel Čapek and František Langer. Čapek’s plays, such as R.U.R. (1920)—which introduced the word "robot" to the world—and The Insect Play (1921), were instrumental in exposing the dehumanizing threats posed by the mechanized, centralized societies of the 20th century.1

Narrative prose also reached a new peak during this interwar period. Writers such as Jaroslav Hašek, Vladislav Vančura, and Ivan Olbracht produced significant works, including Hašek’s The Good Soldier Schweik (1921–23), which famously mocked the authority of the former Austro-Hungarian Empire. Additionally, the period was marked by the great vitality of lyric poetry, with high-quality contributions from poets like Jaroslav Seifert, Vítězslav Nezval, and František Halas.12
