How did the Spanish Civil War interrupt Basque literary publishing?

The Spanish Civil War (1936–1939) caused a complete cessation of literary production in all genres within the Basque language.1

Following the conflict, the publication of Basque-language works remained extremely limited throughout the 1940s and 1950s. This decline was primarily driven by the policy of monolingualism imposed on Spain by Gen. Francisco Franco, which suppressed the use of minority languages. Despite this environment of suppression, the Euskaltzaindia (Royal Academy of the Basque Language) continued its efforts to standardize the language, eventually developing the unified written form known as Euskara Batua.1
