Blaverism (Valencian: blaverisme, IPA: [blaveˈɾizme]) is a Valencian regionalist ideology in the Valencian Community (Spain) that emerged with the Spanish transition to democracy characterised by strong anti-Catalanism, born out of its opposition to Joan Fuster's book Nosaltres, els valencians (1962), which promoted the concept of the Catalan Countries which includes Valencia.[1] They consider Fuster's ideas as an imperialist Catalan nationalist movement that tries to impose Catalan domination upon Valencia. Blaverism takes its name from the blue (Valencian: blava) fringe which distinguishes the Valencian flag from other flags with a common origin, particularly from the Catalan.
The term "blaverism" originally had a negative connotation, often pejorative connotation,[2] which is still kept among the social groups who consider the blaverism a type of far-right movement.[3][4] In the 21st century, the term blaver is recognised by different Valencian language dictionaries, including the official dictionary made by the Acadèmia Valenciana de la Llengua. In its origins in the second half of the twentieth century, blaverism was a populist and heterogeneous movement, which grouped together regionalists and supporters of Valencian foral civil law. Support for blaverism has been strongest in the city of Valencia and in the areas immediately surrounding it.
