The existence of Apaches as a semi-organised gang-culture in Paris during the early 1900s was exaggerated in media coverage, although it did reflect the reality of a higher proportion of young males among the city population than elsewhere in France.
With the outbreak of World War I in August 1914 the wholesale mobilisation of this class for military service led to a reduction of violent street crime and the subsequent fading of Apache mythology.
After 1919 the incidence of urban violence returned to pre-war levels but without such symbols supposedly favoured by Apaches, such as the wearing of coloured sashes or the carrying of specially designed weapons.
Emilio Ghione's La Mort series of films—of which only I topi grigi (The grey rats, 1918), Anime buie (Dark souls, 1916) and a fragment of Dollari e Fracks (Dollars and dinner jackets, 1919) still exist—was about the adventures of a 'noble' Apache in the Parisian underworld and further afield.
The popular Italian pulp fiction writer Aristide Marino Gianella also wrote a serial novel called Gli apache parigini, which was first available in short installments and then within a complete volume.
