In 1928, FIGC had decided a reform of the league structure of Italian football. The top-level league was the National Division, composed by the two divisions of Serie A and Serie B. Under them, there were the local championship, the major one being the First Division, that in 1935 will take the name of Serie C. In order to allow the new league structure for 1935-36 season, the winners of the eight groups of First Division would be admitted to the final rounds, where two tickets of promotion to Serie B were available, while the last eight clubs of each group had to be relegated to the Regional Leagues.
