The Unió Catalanista (in English: Catalanist Union) was a Catalanist political group, initially conservative, formed in Barcelona in 1891,[1][2] from the union of various Catalanist trade unions and associations that came into contact as a result of the resistance against Article 15 of the Civil Code, which they considered to be an attack on Catalan civil law.

In 1897 it modified its statutes and was joined by new associations, groups, newspapers and individuals.

The latter, who advocated participation in the political system, split from the Unió in 1899 and created the Centre Nacional Català under the presidency of Narcís Verdaguer.

[4] The Unió Catalanista then called an assembly in Terrassa at which it decided to enter politics and ask for the economic agreement.

In the 1932 regional elections it won a seat in the Catalan parliament, in coalition with the Republican Left of Catalonia.
