|2017 K League Challenge|
The K League Challenge is a South Korean professional league for association football clubs. Being the second tier of the South Korean football league system, it is currently contested by ten clubs, and operates on a system of promotion and relegation with the K League Classic.
In 2011 the original K League announced a plan to begin a promotion and relegation system between the K League and a proposed second division. The K League then took steps to create the new second division, mainly with the addition of a split-system during the 2012 K-League season in which the bottom clubs are placed in a competition for safety with the last placed club being relegated to the new second division (originally it was going to be two clubs relegated but the withdrawal of Sangju Sangmu FC meant only one would be relegated).
On 3 January 2013 the official name of the Second Division was announced as the K League while the original K League was changed to K League Classic along with the new logo. This name change caused some degree of confusion and controversy, and on 11 March 2013 the official name was changed to K League Challenge.
