The Italian Ministry of the Navy had its origins in the
Kingdom of Sardinia, which on 11 October 1850 divided its Ministry of War and the Navy, creating a separate Ministry of War and moving oversight of the
Royal Sardinian Navy to the Ministry of Agriculture and Commerce. By a royal decree of 23 October 1853, the Kingdom of Sardinia established a separate Ministry of the Navy. When
Italy unified in 1861 to form the
Kingdom of Italy, the last
King of Sardinia became the
King of Italy as
Victor Emmanuel II, and in that year Italy's
Fourth Cavour government drew upon the Sardinian Ministry of the Navy to create an Italian Ministry of the Navy to oversee the new Italian
Regia Marina ("Royal Navy"). The new ministry also had oversight responsibility for the Italian
merchant marine, with control of the Division of the Merchant Marine and Maritime Health (), which in 1874 was renamed the General Directorate of the Merchant Marine (). The ministry retained its merchant marine responsibilities until 1916, when oversight of the merchant marine was transferred to the
Ministry of Maritime and Railway Transport (). Under the
fascist government of
Prime Minister Benito Mussolini, the
Regia Aeronautica ("Royal Air Force") was created in 1923 and took over aviation responsibilities from the
Regia Marina and Italian
Royal Army. On , a new
Ministry of Aeronautics took control of the oversight of aviation activities which previously had fallen under the Ministry of the Navy or the
Ministry of War. Mussolini himself served as the Minister of the Navy from to and from to . Italy entered
World War II on the side of the
Axis powers in June 1940. In August 1943, the ministry regained oversight of the Italian merchant marine when the General Directorate of the Merchant Marine was transferred from the
Ministry of Communications () to the Ministry of the Navy, where it became an
undersecretariat. In September 1943, Italy
surrendered to the
Allies and switched sides, becoming a
co-belligerent with the Allies. Between September 1943 and the surrender of
Nazi Germany in May 1945, with the Kingdom of Italy
in control of southern Italy, the ministry oversaw the
Regia Marina′s forces as they fought as the
Italian Co-belligerent Navy () alongside Allied forces in the
Italian campaign and simultaneously in the
Italian Civil War against the
Italian Social Republic, which the Germans established as a
puppet state in northern Italy under Mussolini and which continued to fight on the Axis side. In 1946, the
Italian Republic replaced the Kingdom of Italy. Under the Republic, the Ministry of the Navy, renamed
Ministero della marina militare (literally "Ministry of the Military Navy"), had oversight of what was now called the
Marina maritime, literally "Military Navy" but usually translated as "
Italian Navy." Upon the establishment of the Republic, the Ministry of the Navy again lost its responsibility for the merchant marine, oversight of which was transferred to a new
Ministry of the Merchant Marine () on Under the
Third De Gasperi government, by Decree Number 17 of the
provisional head of state on 4 February 1947, the Ministry of the Navy, Ministry of War, and Ministry of Aeronautics were abolished as of 14 February 1947, and their responsibilities were transferred to a new, unified
Ministry of Defence. ==Organization==
