Switzerland Super League

The Swiss Football Association was founded in 1895, but were initially unable to organize an annual competition, citing the teams' travel costs. The first unofficial championship, competed for the Ruinart Cup, was organized by Genevan newspaper La Suisse sportive as a response in 1897. It was mainly contested by teams from the French-speaking area, with the exception of FC Zürich and Grasshopper Club Zürich, the latter of which eventually won the tournament. The inaugural official championship was therefore organized for the following season, in 1898–99, and won by Anglo-American Club against Old Boys Basel. It was, however, only competed by Swiss-German teams (with the exception of a team from Neuchâtel) until 1900, due to a dispute about playing on Sundays.

Teams from the canton of Zürich continued to dominate the league until 1907–08, with Grasshoppers winning a further three, FC Winterthur winning two, and FC Zürich winning one title. Other champions from that time included Servette, St. Gallen, and Young Boys, who subsequently also won three in a row from 1908–1911. Over the next decade, FC Aarau, Montriond LS (now Lausanne-Sport), SC Brühl, and Cantonal Neuchâtel FC each won their first title as nobody managed to monopolize the league. During the 1920s and 1930s, championships were achieved almost exclusively by modern Super League regulars, namely Grasshoppers, Servette, Zürich, Young Boys, Lausanne-Sport, and FC Lugano. FC Bern was the exception in 1923; however, their championship was denied after the use of an unauthorized player.

The league was reformed into the Nationalliga in 1931 and initially changed from three regional groups to two groups with 9 teams each. The league composition thereafter varied on several occasions, ranging from 12 to 16 teams competing in a single group. Contrary to its neighboring countries, national football was not suspended during World War II due to Switzerland's neutrality, but the post-war years nevertheless brought change. The 1944–45 season saw the separation of the league into the Nationalliga A and B, with the winner of the former declared Swiss champion. The 1946–47, 1947–48, 1952–53, and 1953–54 seasons saw further maiden victories achieved by FC Biel-Bienne, AC Bellinzona, FC Basel, and FC La-Chaux-de-Fonds, respectively. In 1954, broadcasting rights were sold to SRG SSR for the first time, with the company initially being restricted in showing games on TV. For the 1956–57 season, jersey numbers were declared mandatory, with Young Boys initiating an unprecedented streak of four titles the same season.

The 1966–67 season first saw the emergence of Basel as a dominant team, as they won 7 of the following 14 seasons. As shirt sponsors first appeared by 1976, the SRG SSR refused to broadcast teams that wore advertisements on their kits. As a result, the broadcaster and the league reached a compromise, where the former would only show sponsors in reports lasting a maximum of 6 minutes, and teams would be obligated to wear neutral jerseys for longer appearances. The 1980s and 1990s saw Grasshoppers dominate and Neuchâtel Xamax, FC Luzern, and FC Sion win their first titles in 1986–87, 1988–89, and 1991–92. In 1985, the number of foreigners on a team was increased from one to two, promptly leading to a new transfer record of 1.3 million francs with Servette acquiring Mats Magnusson. In 1992–93 Aarau won the championship the first time in 79 years, while St. Gallen earned their first title in 97 years at the turn of the millennium.

The rebranding of the Nationalliga A into the Super League occurred in 2003, when the league was restructured from 12 to 10 teams for the 2003–04 season, simplifying the format by removing the relegation playoff round. A return to 12 teams was discussed on multiple occasions in 2009 and 2018, but ultimately rejected, among others due to reservations about the early relegation battle.

This new era initially proved to be one of domination for Basel, as 11 of the first 14 seasons were won by them, including a record-breaking streak of 8 championships between 2009 and 2017. After a change in leadership in 2017, however, they were dethroned by Young Boys, who won the next four straight championships.

In April 2022, another proposal by the SFL committee to increase the league size to 12 was announced. The proposal includes three stages: an initial round-robin qualifying stage with all 12 teams (22 rounds); an intermediary stage, with two groups (1st-6th placed in the Championship and 7-12th placed in the Qualification Group) of six teams each (10 rounds); the format of the third and final playoff phase is still to be determined. Despite pushback from fans and a general negative response from club officials, the proposal to increase the league size as well as the proposed format change were approved by the general assembly of the Swiss Football League on 20 May 2022.

The details of the final playoff stage was also finalized:

• The first and second placed teams of the Championship Group will play a best of three Championship Final. The first placed team has home advantage in the first and third game.
• The 3rd-6th placed teams of the Championship Group and the 1st-4th placed teams of the Qualification Group (eight teams total) will play a three round playoff for the remaining spots in international championships. The playoff will be carried out according to the European model, with home and away games except in the final match. Teams are seeded according to their placement.
• The 5th placed team of the Qualification Group will play a relegation playoff against the second placed team of the Challenge League. The last placed team is relegated directly.

The new format will be implemented for the 2023–24 season, while the transitional 2022–23 season will have only the last placed team playing a relegation playoff against the 3rd place of the Challenge League. A change of format for the Swiss Challenge League is not yet clear.

In October 2022, following heavy fan protests, reigning champions FC Zürich officially submitted a request to repeal the decision to introduce the play-off modus. Instead they propose to use the system used in the Scottish Premiership. An according fan petition gathered 18,000 signatures (including national team star Breel Embolo) in the first day of its publication and Super League heavy-weights BSC Young Boys officially supported the motion immediately. This triggered a renewed vote by the general assembly.

On 11 November 2022, the new proposal to instead use the "Scottish Model" was approved by the general assembly of the Swiss Football League. By the time of the vote, the petition opposing the play-off system had gathered over 60,000 signatures. The increased number of teams was not up for a re-vote, though. The new format is as follows:

• In a first phase all twelve teams play each other three times each, for a total of 33 matchdays.
• Following that, the league is split into two groups of six each, one "Championship Group" and one "Relegation Group".
  • Each team will play every other team in their group one time (five matches each), for a total of 38 matchdays.
  • The Championship Group will play for the title of Swiss Football Champion and qualification to European championships.
  • The Relegation Group will play against relegation (last place) and qualification to the relegation play-off (second-to-last place).
• Points won in the first phase are carried over to the second phase.
