German colonial empire
After its victory in World War I, it was agreed that Italy would not receive territories from the defeated German colonial empire. It was divided between France, Japan and the British Empire, but Italy would be rewarded some bordering areas from the British and French colonial possessions. That was considered by Italians to be very little compensation for their sacrifices in the bloody war, which was one of the reasons of the rise to power in Italy of Mussolini's fascism.
