The economic recovery was very slow and it was not until the mid-1950s that the economy reached the prewar levels of 1936. In 1959–1974 Spain experienced the second fastest economic expansion in the world in what became known as the Spanish Miracle and Catalonia prospered greatly from the expansion as Spain's most important industrial and tourist zone. In 1975 Franco died, bringing to an end his dictatorial regime, and in 1978 Catalonia voted overwhelmingly for the new democratic Spanish constitution that recognised Catalonia's autonomy and language.
