Marshal of Italy was a rank in the Royal Italian Army. Originally created in 1924 by Italian dictator Benito Mussolini for the purpose of honoring generals Luigi Cadorna and Armando Diaz, the rank was granted to several other general officers from 1926 to 1943. The rank was the highest in the Italian Army prior to the creation of the rank of First Marshal of the Empire in 1938. The rank of Marshal of Italy was abolished in 1946 with the creation of the Italian Republic. The equivalent Royal Navy rank was Grand admiral, while the equivalent Air Force rank was Marshal of the Air Force.
