The K League Classic was founded in 1983 as the Korean Super League, with five member clubs. The initial five clubs were Hallelujah FC, Yukong Elephants, POSCO Dolphins, Daewoo Royals, Kookmin Bank FC. Hallelujah FC won the inaugural title, finishing one point ahead of Daewoo Royals to lift the crown.
In 1998, Korea's football league was reformed and renamed the K League. (K League was official orthography by 2012) Since its creation, the league has expanded from an initial 5 to 16 clubs. Of the 5 inaugural clubs, only Yukong Elephants, POSCO Dolphins, and Daewoo Royals remain in the K League; Kookmin Bank FC dropped out of the league at the end of 1984, and Hallelujah FC followed the season after.
In 2013, K League introduced the division system. The first division's name is K League Classic, the second division's name is K League Challenge and the comprehensive brand name is K League.
