History

Until the 1970s, South Korean football operated two major football leagues, the National Semi-professional Football League and the National University Football League, but these were not professional leagues in which footballers could focus on only football. In 1979, however, the Korea Football Association (KFA)'s president Choi Soon-young planned to found a professional football league,{{cite web |url=https://newslibrary.naver.com/viewer/index.nhn?articleId=1979013100329208004&editNo=2&printCount=1&publishDate=1979-01-31&officeId=00032&pageNo=8&printNo=10256&publishType=00020 |script-title=ko:"崔蹴協회장 후원회는 法人등록 北韓·中共과도 교류" |language=ko |website=Naver |publisher=Kyunghyang Shinmun |date=31 January 1979 |access-date=28 November 2020 |archive-date=14 February 2024 |archive-url=https://web.archive.org/web/20240214111318/https://newslibrary.naver.com/viewer/index.naver?articleId=1979013100329208004&editNo=2&printCount=1&publishDate=1979-01-31&officeId=00032&pageNo=8&printNo=10256&publishType=00020 |url-status=live }} and made South Korea's first professional football club Hallelujah FC the next year.{{cite web |url=https://newslibrary.naver.com/viewer/index.nhn?articleId=1980041800239108001&editNo=1&printCount=1&publishDate=1980-04-18&officeId=00023&pageNo=8&printNo=18161&publishType=00010 |script-title=ko:韓國球界 「프로時代」올것인가 「할렐루야」蹴球團 10월 창단을 계기로 본 「難題」속의 期待‥‥그展望과문제점 |language=ko |website=Naver |publisher=The Chosun Ilbo |date=18 April 1980 |access-date=28 November 2020 |archive-date=14 February 2024 |archive-url=https://web.archive.org/web/20240214111226/https://newslibrary.naver.com/viewer/index.naver?articleId=1980041800239108001&editNo=1&printCount=1&publishDate=1980-04-18&officeId=00023&pageNo=8&printNo=18161&publishType=00010 |url-status=live }} After the South Korean professional baseball league KBO League was founded in 1982, the KFA was aware of crisis about the popularity of football.{{cite web |url=https://sports.news.naver.com/news.nhn?oid=139&aid=0001993153 |script-title=ko:[김덕기의 프로축구 10950] 슈퍼리그, 1983년 5월8일 팡파르 |language=ko |website=Naver |publisher=Sportalkorea |date=16 January 2013 |access-date=28 November 2020 |first=Deok-gi |last=Kim |archive-date=13 May 2023 |archive-url=https://web.archive.org/web/20230513041211/https://sports.news.naver.com/news.nhn?oid=139&aid=0001993153 |url-status=live }} In 1983, it urgently made the Korean Super League with two professional clubs (Hallelujah FC, Yukong Elephants) and three semi-professional clubs (POSCO Dolphins, Daewoo Royals, Kookmin Bank) to professionalize South Korean football. Then, the Super League accomplished its purpose after existing clubs were also converted into professional clubs (POSCO Atoms, Daewoo Royals) and new professional clubs joined the league. In the early years, it also showed a promotion system by giving qualifications to the Semi-professional League winners. (Hanil Bank in 1984, Sangmu FC in 1985)

However, the number of spectators was consistently decreased despite KFA's effort, and so the professional league, renamed as the Korean Professional Football League, operated home and away system to interest fans since 1987.{{cite web |url=https://newslibrary.naver.com/viewer/index.nhn?articleId=1987022400329209001&editNo=2&printCount=1&publishDate=1987-02-24&officeId=00032&pageNo=9&printNo=12741&publishType=00020 |script-title=ko:프로蹴球 명예回復 선언 |language=ko |website=Naver |publisher=Kyunghyang Shinmun |date=24 February 1987 |access-date=28 November 2020 |archive-date=14 February 2024 |archive-url=https://web.archive.org/web/20240214111223/https://newslibrary.naver.com/viewer/index.naver?articleId=1987022400329209001&editNo=2&printCount=1&publishDate=1987-02-24&officeId=00032&pageNo=9&printNo=12741&publishType=00020 |url-status=live }} On 30 July 1994, the Professional League Committee under KFA was independent of the association, and renamed as the "Korean Professional Football Federation". In 1996, South Korean government and the Football Federation introduced a decentralization policy to proliferate the popularity of football nationally in preparation for the 2002 FIFA World Cup, which they wanted to host. Several clubs located in the capital Seoul moved to other cities according to the new policy, but this was abolished after only three years and is regarded as a failed policy because it gave up the most populous city in South Korea. In 1998, the league was renamed again as current K League.{{cite web |url=https://sports.news.naver.com/news.nhn?oid=015&aid=0003076649 |script-title=ko:서울 연고 이랜드프로축구단 출범…FC서울과 '투톱' |language=ko |website=Naver |publisher=The Korea Economic Daily |date=2 May 2014 |access-date=28 November 2020 |archive-date=18 May 2023 |archive-url=https://web.archive.org/web/20230518101545/https://sports.news.naver.com/news.nhn?oid=015&aid=0003076649 |url-status=live }}

It had the current format by abolishing the K League Championship and the Korean League Cup after the 2011 season, and being split into two divisions in 2013. The first division's name was the K League Classic, and the second division's name was the K League Challenge at the time. The fact that both the first and the second divisions had very similar names caused some degree of confusion and controversy.{{Cite news |url=http://news.sportsseoul.com/read/soccer/1143741.htm |script-title=ko:위원석의 하프타임 'K리그'에 새로운 이름을 붙여주자 |publisher=Sports Seoul |date=19 February 2013 |language=ko |url-status=dead |archive-url=https://web.archive.org/web/20131211180244/http://news.sportsseoul.com/read/soccer/1143741.htm |archive-date=11 December 2013}} Beginning with the 2018 season, both divisions were renamed the K League 1 and the K League 2 respectively.

In February 2021, an OTT service for international markets called K League TV was officially launched.{{cite web |last1=Jee-ho |first1=Yoo |title=K League launches new OTT service for international markets |url=https://en.yna.co.kr/view/AEN20210223009400315 |website=Yonhap News Agency |access-date=14 February 2024 |language=en |date=23 February 2021}}

Structure

{{main|South Korean football league system}}

Below K League 1 is the second-tier K League 2, and both form the K League as professional championships. Under them, there are two semi-professional leagues (K3 League and K4 League) and three amateur leagues (K5, K6 and K7 Leagues). At present, promotion and relegation exists within each of the three levels (professional, semi-professional, and amateur) but clubs from K3 and below cannot be promoted to the K League. However, the KFA has announced plans to combine the three promotion-relegation systems into one from 2027.{{Cite news |last=Paik |first=Ji-hwan |date=28 March 2024 |title=K League to unify promotion-relegation system across all 7 leagues |url=https://koreajoongangdaily.joins.com/news/2024-03-28/sports/football/K-League-to-unify-promotionrelegation-system-across-all-7-leagues/2013297 |access-date=19 April 2024 |work=Korea JoongAng Daily}}

Since 2021, K League 1 and K League 2 teams have been permitted to field their reserve teams in the K4 League.{{Cite web|title=K3·K4리그 대표자회의 개최...3월 7일 개막|url=https://www.kfa.or.kr/layer_popup/popup_live.php?act=news_tv_detail&idx=22225&div_code=news&check_url=bGF5ZXI=|access-date=27 February 2021|website=KFA|language=en|archive-date=9 February 2021|archive-url=https://web.archive.org/web/20210209002559/https://www.kfa.or.kr/layer_popup/popup_live.php?act=news_tv_detail&idx=22225&div_code=news&check_url=bGF5ZXI=|url-status=live}}

Restriction of foreign players

{{see also|List of foreign K League 1 players|l1=List of foreign K League 1|List of foreign K League 2 players|l2=K League 2 players}}

At the inception of the K League in 1983, only two Brazilian players made rosters. At the time, rules allowed each club to have three foreign players and that the three could also play simultaneously in a game. From the 1996 season, each team had five foreign players among whom three could play in a game at the same time. Since 1999, foreign goalkeepers are banned from the league because South Korean clubs excessively employed foreign goalkeepers after watching Valeri Sarychev's performances at that time.{{cite news |url=https://tv.kakao.com/channel/2663796/cliplink/390767801 |script-title=ko:[원투펀치 328회 2부] K리그 역대 베스트 키퍼 Top7 |language=ko |website=TV.Kakao.com |publisher=Daum |date=24 September 2018 |access-date=30 April 2020 |archive-date=5 October 2021 |archive-url=https://web.archive.org/web/20211005094836/https://tv.kakao.com/channel/2663796/cliplink/390767801 |url-status=live }} In 2001 and 2002, the limit on foreign players was expanded to seven but only three could play in a game at the same time. The limit was lowered to five in 2003, four in 2005, and three in 2007. Since 2009, the number of foreign players went back up to four per team, including a slot for a player from AFC countries. Between 2020 and 2024, Southeast Asian players could be registered under the ASEAN Quota.{{cite web |title=News: K League to Introduce ASEAN Quota in 2020 |url=http://www.kleagueunited.com/2019/04/news-k-league-to-introduce-asean-quota.html |publisher=K League United |access-date=21 December 2019 |archive-date=25 April 2023 |archive-url=https://web.archive.org/web/20230425233010/http://www.kleagueunited.com/2019/04/news-k-league-to-introduce-asean-quota.html |url-status=live }}

Relocation of clubs

{{main|K League decentralization policy}}

In early years, the hometowns of K League clubs were determined,{{cite web |archive-url=https://web.archive.org/web/20131005100315/http://www.kleague.com/kr/sub.asp?avan=1001125100 |url=http://www.kleague.com/kr/sub.asp?avan=1001125100 |script-title=ko:K League history - 1983 season |language=ko |publisher=K League |access-date=2020-12-24 |archive-date=2013-10-05}} but they were pointless in substance because the clubs played all K League matches by going around all stadiums together. The current home and away system is being operated since 1987. The clubs were relocated from provinces to cities in 1990, but clubs are currently based in their area regardless of province and city since 1994. In 1996, the decentralization policy was operated. In result 3 clubs based in Seoul were relocated. Since 1996, it is obligatory for all clubs to include hometown name in their club name.
