Revolt of the Brotherhoods
During the Bourbon monarchy of the 18th century, the central authorities in Spain made various efforts towards centralisation, notably the Nueva Planta decrees extinguishing most of the ‘’fueros’’ – long-standing privileges and institutions of different territories. Some kingdoms, like Navarre and the Lordships of the Basque Country, did maintain constitutions based on their historical rights and laws, while other kingdoms revolted against this process of centralisation demanding a return of their derogated laws as well as better living conditions (Revolt of the Comuneros, Revolt of the Brotherhoods, Catalan Revolt).
