How did Sardinia become a self-governing region of Italy in 1948?

Sardinia became a self-governing regione of Italy in February 1948 as part of the post-World War II restructuring of the Italian state.1

Following the end of the war, the movement for Sardinian autonomy—which had been suppressed during the rise of Benito Mussolini’s Fascist regime—was revived. During the drafting of the new Italian constitution, the Constituent Assembly recognized the need to address the unique linguistic and ethnic differences of populations in outlying zones.12

Consequently, the Constitution of the Republic of Italy, which took effect on January 1, 1948, promised the establishment of autonomous regional governments. Sardinia was one of five regions granted these special powers to manage its own legislative and administrative affairs, reflecting a commitment to decentralization and a departure from the centralized control of the Fascist era.23
