This championship was organized by the same league governing Serie A and Serie B (the "Direttorio Divisioni Superiori"), even if, as opposed to the two higher divisions, it was structured in local groups with geographical criteria. The number of clubs belonging to the Prima Divisione continued to increase every year, until FIGC decided to rename it as "Serie C" (at the beginning of the 1935–36 season) while a subsequent large reduction in 1948 led to the creation of a sole national division in 1952–53.
