The Italian participation on the Eastern Front represented the military intervention of the Kingdom of Italy in the Operation Barbarossa, launched by Nazi Germany against the Soviet Union in 1941. The commitment to actively take part in the German offensive was decided by Benito Mussolini a few months before the beginning of the operation, when he became aware of Adolf Hitler's intention to invade, but it was confirmed only on the morning of 22 June 1941, as soon as the Italian dictator was informed that same day the German armies had invaded the Soviet Union.
