In this article, I have shown how Catalan nationalism mutated in the last years. Since 1979 Catalonia enjoyed unprecedented political self-government, however, its political autonomy was not enough for the independence movement. With the economic crisis of 2008, they declared that the time of independence has finally arrived, and in 2017 a bizarre independence that lasted a few seconds was proclaimed. Catalan nationalism was traditionally pragmatic, but since then, this is no longer the case. It converted to a new nationalism that in the name of a democracy of the people divided Catalonia by antagonism. As I have shown, the new Catalan nationalism is today a populism of secession.
