1922–23 Prima Divisione
The 1922-23 Prima Divisione was the twenty-third edition of the Italian Football Championship and the second branded Prima Divisione. In a highly political previous season of Italian football, two separate and rival Italian Football Championships were organised by disputing parties. Hence why 1922-23 Prima Divisione was the twenty-third edition and not twenty-second. The 1922–23 Prima Divisione was the eighth Italian Football Championship won by Genoa.
Format
All five seasons of Prima Divisione were scheduled as regional competitions, leading to a national final.Due to the high numbers of participants, under the agreement with the Northern League, the FIGC had to organize a qualification tournament in July, in order to reduce them to three rounds of 12 sides each.
