The Italian Social Republic, known prior to December 1943 as the National Republican State of Italy, but more popularly known as the Republic of Salò, was a Nazi-German puppet state with limited diplomatic recognition that was created during the latter part of World War II, which existed from the beginning of the German occupation of Italy in September 1943 until the surrender of German troops in Italy in May 1945.

It was re-constituted later in 1943 and deployed to Sardinia and when the expected Allied invasion of Sardinia failed to materialise, the division was moved to Italy. It was engaged in actions against the Allies in Italy from 1943 to April 1945 when the division was listed as "destroyed" in the Po River valley.
