Mario Scelba was an Italian politician who served as the 33rd prime minister of Italy from February 1954 to July 1955. A founder of the Christian Democracy, Scelba was one of the longest-serving Minister of the Interior in the history of the republic, having served at the Viminale Palace in three distinct terms from 1947 to 1962. A fervent pro-Europeanist, he was also President of the European Parliament from March 1969 to March 1971.
Known for his law and order policies, Scelba was a key figure in Italy's post-war reconstruction, thanks to his drastic reorganization of the Italian police, which came out heavily disorganised from the war.
