The Constitution of the Italian Republic was enacted by the Constituent Assembly on 22 December 1947, with 453 votes in favour and 62 against. The text, which has since been amended 15 times, was promulgated in the extraordinary edition of Gazzetta Ufficiale No. 298 on 27 December 1947. The Constituent Assembly was elected by universal suffrage on 2 June 1946, at the same time as a referendum on the abolition of the monarchy. The Constitution came into force on 1 January 1948, one century after the Statuto Albertino had been enacted. Although the latter remained in force after Benito Mussolini's March on Rome in 1922, it had become devoid of substantive value.
