A national second-tier league of Indonesian football was initially established as the Liga Indonesia First Division in 1994. Following the formation of the Indonesia Super League in 2008 as the new top-tier competition, the Liga Indonesia Premier Division was relegated to the second tier. Due to conflicts between PT Liga Indonesia (LI) and PT Liga Prima Indonesia Sportindo (LPIS), two separate Premier Division competitions were held during the 2011âÂÂ12 and 2013 seasonsâÂÂone under the ISL and the other under the Indonesian Premier League. In January 2017, PSSI rebranded the Premier Division as Liga 2. In August 2025, PSSI rebranded again the Liga 2 as Championship and PT Liga Indonesia Baru (PT LIB) rebranded as I League.
Several tournaments were organized in the place of a second-tier league during Indonesia's suspension from FIFA between December 2015 and May 2016. The winners are not officially recognized as second-tier champion.
