Several literary events occurred in the aftermath of World War II. The writer Christian Dotremont helped establish the international art group COBRA (1948–51), writing portraits of various members of the group and text for their exhibition catalogs. In 1952 a biennial international conference of poets and critics was founded, held at Knokke-Het Zoute and later at Liège. Furthermore, the poet and critic Fernand Verhesen established the Centre International d’Etudes Poétiques in 1954. It is also notable that literary periodicals, which were usually organs for political or literary groups of writers, continued to be influential, especially Le Journal des Poètes.

The novel became less regional than formerly, and in fact was often set in foreign surroundings; generally it subordinated action to detailed analysis of characters’ reactions in somewhat contrived situations. Albert Ayguesparse, earlier associated with proletarian literature, built upon the realism of the interwar period, while Hubert Juin combined Ardennes regionalism with social and psychological awareness. Female writers such as Dominique Rolin, Jacqueline Harpman, Maud Frère, and Louis Dubrau (pseudonym of Louise Scheidt) were concerned primarily with the problems of personal relationships. Rolin’s insistent and incisive explorations of personal origins and family life often utilized experimental language and form, as in Le Gâteau des morts (1982; The Deathday Cake). Breadth of subject matter and meticulous style characterized the work of Suzanne Lilar, author of La Confession anonyme (1960; “The Anonymous Confession”) and others. Lilar’s daughter, Françoise Mallet-Joris, established her reputation with Le Rempart des béguines (1951; Into the Labyrinth), the first part of an Antwerp trilogy. History, mythology, and psychoanalysis were merged in the work of the psychoanalyst Henry Bauchau in such novels as Œdipe sur la route (1990; Oedipus on the Road). Jacques-Gérard Linze and Guy Vaes (Octobre long dimanche, 1956; October Long Sunday), on the other hand, were particularly influenced by modernist fictional forms. Thomas Owen continued the fantastic tradition begun by Jean Ray. The fiction of Gaston Compère was both extravagant and intense. Notable younger novelists included Pierre Mertens and Conrad Detrez (both of whose writing is marked by an international political awareness), Jean-Claude Pirotte, Jean-Philippe Toussaint, Eugène Savitzkaya and Francis Dannemark (both of whom also wrote poetry), and the fiercely iconoclastic Marcel Moreau. The most successful young Belgian novelist of the 1990s was Amélie Nothomb, two of whose novels of the ’90s—Le Sabotage amoureux (1993; Loving Sabotage) and Stupeur et tremblements (1999; Fear and Trembling)—were translated into English at the turn of the 21st century.

Postwar poetry was at first dominated by a Neoclassical tendency in which such poets as Robert Vivier, Géo Libbrecht, Jean Tordeur, and Edmond Vandercammen often reverted to regular metrical forms in poems on eternal themes. Liliane Wouters, Lucienne Desnoues, Jeanine Moulin, and Andrée Sodenkamp helped to legitimate poetry written by women. Maurice Carême and the chansonnier Jacques Brel gained international fame for the popular appeal of their lyrics. With limpid irony, Franƈois Jacqmin wrote elemental, philosophical poetry. Christian Dotremont developed his own unique calligraphic poems known as “logograms.” The lucid verse of André Schmitz offered a fusion of traditional and modern forms. In the 1970s new investigations of the frontiers of poetic language marked the work of Jean Daive, Jacques Izoard, Werner Lambersy, Jacques Crickillon, and Christian Hubin, while Jean-Pierre Verheggen combined avant-gardism with Walloon populism. Among the most talented younger poets were William Cliff and Guy Goffette.

Outstanding dramatists, generally writing in an ethical rather than historical vein, were Georges Sion, Jean Mogin, and Charles Bertin, whose Prétendants (1947), a modern version of the Ulysses story, was played abroad as Love in a Labyrinth. Other dramatists of note were Jean Sigrid and Jean Louvet, who drew on his working-class Walloon background. Jewish and Flemish, respectively, the playwrights René Kalisky and Paul Willems explored questions of personal and national identity in highly idiosyncratic dramatic forms. During the 1980s Paul Emond (an accomplished novelist) and Jean-Marie Piemme also established reputations in the theatre.

The 1970s and ’80s brought new critical awareness of French-language Belgian literature as a distinctive presence within international francophone culture. The term “belgitude” enjoyed currency as a unifying concept but was soon perceived as an unhelpful stereotype. A number of critics—such as Marc Quaghebeur, Jean-Marie Klinkenberg, Paul Aron, Christian Berg, and Frans De Haes—continued to reassess the history and quality of Belgian literature in French while recognizing its linguistic and cultural diversity.
