Why the 1931 conistution was revised in 1955?

The 1931 Constitution of Spain was revised in 1955 primarily due to the political and social changes following the Spanish Civil War and the establishment of Franco's Dictatorship. The need for a more authoritarian framework became apparent as the regime sought to consolidate power and suppress opposition. The revision aimed to legitimize Franco's rule and align the constitution with the regime's ideologies, reflecting a shift towards a more centralized and controlled governance structure. This revision ultimately reinforced the authoritarian nature of the regime, sidelining democratic principles established in the original 1931 Constitution.
