Languages of Catalonia
The main cause of Spanish and Catalan social bilingualism in modern Catalonia was large-scale migration from the rest of Spain during the 20th century, as Catalonia started a significant industrialization which demanded an increased workforce from elsewhere. Spanish has historically been spoken among a minority of civil servants born in other regions in Spain and among segments of the wealthiest bourgeoisie. Spanish has also been spoken as a second language by most Catalans, as it has been the only official language over long periods since the eighteenth century.
Catalonia
After the end of Francoist Spain, the newly established self-governing democratic institutions in Catalonia embarked on a long-term language policy to recover the use of Catalan and has, since 1983, enforced laws which attempt to protect and extend the use of Catalan. This policy, known as the "linguistic normalisation" ("normalització lingüística" in Catalan, "normalización lingüística" in Spanish) has been supported by the vast majority of Catalan political parties through the last thirty years. Some groups consider these efforts a way to discourage the use of Spanish, whereas some others, including the Catalan government and the European Union consider the policies respectful, or even as an example which "should be disseminated throughout the Union".
