In the 1931-1932 the National League championship was created, although only two years later the control body of the same name was born.
The reform that gave birth to the single group championship was implemented for the 1933-1934 season.
With the reform called "Wiederkehr project", approved during the extraordinary federal assembly held in Lugano on 9 October 1943, starting from the 1944-1945 season the National League championship was split into two distinct categories, called Lega National A and National League B.,[3] each of which is made up of 14 teams[4] On 5 July 1960, a circular from the Transfer- und Aufsichtskommission der National-Liga (TRAKO), the Supervisory Commission for transfers of the National League, announced the possibility of transferring a player from one club to another, in exchange of a sum of money, without a request for authorization to TRAKO itself.
As a consequence of this, the status of Swiss footballers, who until then had remained officially "amateur", became "semi-professional".
