This study focuses on the Statute-related parliamentary debates of the Catalan and Valencian autonomous regions and analyses the conceptions of the political communities defended by the political parties, both of Spain, Valencia and Catalonia and the relationship between them. The goal is to analyse the differences over time and across ideologies of the identification patterns and the preferences with regards to the territorial organisation of the Spanish state and the arguments used to legitimise these positions. Unsurprising, the investigation shows that the secessionist crisis in Catalonia is reflected in many ways, but it also shows indications of conflict or of highly sensitive areas with conflict potential as early as 1979. Furthermore there are significant differences in the ways the political parties act in Valencia and Catalonia, respectively. The results suggest that the decentralisation of the state did not decrease the conflict potential around the territorial organisation of Spain.
