 The Catastro did not lead to a substantial Treasury reform.Such a far-reaching reform was made impossible by the resistance of the privileged.The French revolted against a similar tax system, while Spain made that change silently (the only disturbances were the easily calmed Esquilache Riots of 1766, and those were only tenuously connected with other reformist episodes), because the two countries were in unequal states of transition from feudalism to capitalism.
