The 1921–22 Prima Categoria season was won by Novese.
During the summer of 1921, a dispute between the Federazione Italiana Giuoco Calcio (FIGC) and the largest teams within the league arose. The teams asked for a reduction of the number of participants in the 1a Divisione.
Vittorio Pozzo developed a plan to accommodate the teams' requests, however, after a vote the plan was not passed; the smaller clubs feared that they would disappear if such a reduction was introduced.
Tuscany was added to the main championship as the sixth region. The regional FAs remained with 48 clubs. The preliminary regional phase was the bulk of the tournament, with even twelve matchdays and regular regional football champions, while the following national phase was reduced to a spring tournament of two little groups and a final.
The main tournament was completely divided in six independent sections, and each region had its own football champions that joined the national championship.
Teams
Consequently to the controversy with the secessionist clubs, the Regional FAs quite respected the promotion rules. Only two clubs were added to the six rightful winners of the lower secondary regional tournaments.

Qualifications to the Northern League
This FIGC was very poor, and risks of a general bankruptcy was real. The FIGC had a sole resource, its FIFA membership, during the talks that started with the Northern League.
The rich League proposed that FIGC’s Prima Categoria became the Second Division of its CCI’s championship. An agreement was found in late June: the Colombo Compromise by the boss of newspaper La Gazzetta dello Sport.
The League imposed its idea of a 24 clubs First Division and a 48 clubs Second Division from 1923. The FIGC obtained a special 36 clubs championship for 1922-23, including champions and runner-ups of the disbanded Regional FAs. More, a third club of each regional FA could test its strength against a League bottom club.
To respect as possible its clubs, the FIGC decided a test-match between the third and the forth clubs of each region. All other clubs went directly to Division Two.
^The 1st leg, in Piacenza, suffered the referee's absence so the first match became 'friendly'. Livorno won 4-2.
On July 16 the match was repeated, again in Piacenza, and Livorno won 4-1. Anyway, Piacenza retired before playing the second leg.
