Spain is a spectacular example of a state in which the issue of linguistic rights of regional communities remains a matter of dispute between the political forces of the center and the regions.
The article performs a Catalonia autonomous region based analysis of the key areas of language policy, as well as the features of the existing language situation in the region. Central and regional authorities are considered as the subjects of language policy, their role in the preservation and protection of the regional language is evaluated. The language issue has repeatedly become the cause of a conflict between the center and the region. The linguistic cleavage having developed over the centuries of discrimination in the use of regional languages has not been completely surmounted even today, which becomes one of the prerequisites for the emergence of separatist sentiments in the bilingual region of Spain.
The local language is of particular importance for the regional community, acting as an instrument for its unity and political mobilization. An appeal to the uniqueness of culture and language contributes to regional identity and strengthens the opposition of the regional community to the Spanish majority.
