Corruption in Spain and Catalonia after 2008

The authors decided to deal with the theme of the influence of corruption on the political processes in contemporary Spain and Catalonia. The investigation of this problem requires the reference to both: a political situation in entire state and in the peripheral region, included in the territorial range of Spain. Therefore, the main objective of the article is the attempt to answer three questions: 1) What is the corruptive phenomenon based on and why a public sphere is endangered with it to such a degree?, 2) How did the Spanish citizens react to corruptive processes after 2008?, 3) Did Catalonia, whose politicians regard this region as definitely separate from Spain, differ considerably from a political centre and other regions of the country within intensity of the occurrence of corruptive phenomena after 2008?
