The Bundesliga (sponsor name: Tipico Bundesliga) is the highest division that is organized under the auspices of the Austrian Football Association (ÖFB). From the 2018/2019 season, the competition consists of 12 clubs that play against each other twice. A level lower is played in the 2. Liga, which is called the Erste Liga until 2017. The champion of this division takes the place of the number twelve in the Bundesliga every year.
The Bundesliga was previously organized by the Austrian football association ÖFB. Since 1991 by the "Österreichische Fußball-Bundesliga", who became the tenth union (in addition to the nine "Landesverbände") of the ÖFB. In German 'Bundesliga' can stand for any sport, and for any competition that is organized at federal level (nationally). In Austria, only the football league has the name 'Bundesliga'.
Up to and including the 2017/2018 season, the Bundesliga consisted of ten clubs, each of which played each other four times. At the end of 2016, the Austrian Football Association introduced a competition reform. From the 2018/2019 season onwards, twelve clubs will play in the Bundesliga, competing twice. The competition is then divided into a champion and relegation competition. The number last in the relegation pool relegates to the 2. League and is replaced by the champion of the second class. The winner of the relegation pool plays in a knock-out system for a ticket in the preliminary rounds of the UEFA Europa League.
