The Austrian Football Bundesliga is the top professional football league in Austria. Established in 1974, it features 12 teams competing in a round-robin format, where each team plays the others twice, once at home and once away. The league operates on a system of promotion and relegation with the Austrian 2. Liga. The season typically runs from July to May, culminating in a championship playoff for the top teams. The league is known for its competitive nature and has produced several successful clubs, including Red Bull Salzburg, which has dominated in recent years.
