Gaetano Salvemini was an Italian socialist and anti-fascist politician, historian, and writer. Born in a family of modest means, he became an acclaimed historian both in Italy and abroad, particularly in the United States, after he was forced into exile by Benito Mussolini's Italian fascist regime.

The Italian resistance movement was the Italian resistance groups who fought the occupying forces of Nazi Germany and the fascist collaborationists of the Italian Social Republic during the Second World War in Italy from 1943 to 1945. As a diverse anti-fascist movement and organisation, the Resistenza opposed Nazi Germany, as well as Nazi Germany's Italian puppet state regime, the Italian Social Republic, which the Germans created following the Nazi German invasion and military occupation of Italy by the Wehrmacht and the Waffen-SS from 8 September 1943 until 25 April 1945.
