Persatuan Sepakbola Makassar, commonly known as PSM Makassar, is one of Indonesia's most historic and popular football clubs. Based in Makassar, South Sulawesi, they compete in the country's top flight, Liga 1. The team plays its home matches at the iconic Gelora B.J. Habibie Stadium, known for its electrifying atmosphere. Founded in 1915, PSM is among the oldest clubs in Indonesia, with a name that simply means "Makassar Football Association." The club's history is rich with rivalry and passion, representing the proud people of Sulawesi. Their golden era came in the late 1990s and early 2000s, when they won multiple Indonesian league titles and became a dominant force, powered by legendary local players and shrewd management. The modern era has seen periods of struggle and resurgence, but they remain a formidable side with a massive and fervent fan base known as "Laskar Hijau" (The Green Warriors). The club culture is defined by intense loyalty and a never-say-die attitude. PSM Makassar is more than a club; it is a deeply ingrained symbol of regional identity and pride in Indonesian football.
