The Indonesia Super League (ISL) was the top professional football league in Indonesia, established in 2011. It aimed to improve the quality of football in the country and provide a more competitive environment for clubs. The league featured several teams from across Indonesia, competing for the championship title each season. The ISL was known for its passionate fan base and vibrant matchday atmosphere. However, it faced challenges, including financial issues and governance disputes, which affected its stability. In 2016, the league was replaced by the Liga 1, which continues to serve as the premier football competition in Indonesia.
