Although these terms (modern, contemporary and postmodern) are generally applicable to and stem from Western literary history, scholars often use them in reference to Asian, Latin American and African literatures. Non-western writers, in particular in Postcolonial literature, have been at the forefront of literary evolution during the twentieth century.
Technological advances facilitated lower production cost for books, coupled with rising populations and literacy rates, which resulted in a significant rise in production of popular literature and trivial literature, comparable to the similar developments in music. The division of "popular literature" and "high literature" in the 20th century is overlapped by genres such as detectives or science fiction, despite being largely ignored by mainstream literary criticism for most of the century. These genres developed their own establishments and critical awards; these include the Nebula Award (since 1965), the British Fantasy Award (since 1971) or the Mythopoeic Awards (since 1971).
The Fin de siècle movement of the Belle Époque persisted into the 20th century, but was brutally cut short with the outbreak of World War I (an effect depicted e.g. in Thomas Mann's The Magic Mountain, published 1924). The Dada movement of 1916–1920 was at least in part a protest against the bourgeoisnationalist and colonialist interests which many Dadaists believed were the root cause of the war; the movement heralded the Surrealism movement of the 1920s.
The 1920s were a period of literary creativity, and works of several notable authors appeared during the period. D. H. Lawrence's novel Lady Chatterley's Lover was a scandal at the time because of its explicit descriptions of sex. James Joyce's novel, Ulysses, published in 1922 in Paris, was one of the most important achievements of literary modernism.
