Editing Go (game) (section)

=== Spread to Korea and Japan ===
Go was introduced to Korea sometime between the 5th and 7th centuries CE, and was popular among the higher classes. In Korea, the game is called '''''baduk''''' ({{Korean|hangul=바둑}}), and a variant of the game called [[Sunjang baduk]] was developed by the 16th century. Sunjang baduk became the main variant played in Korea until the end of the 19th century, when the current version was reintroduced from Japan.<ref>{{Citation | url = http://english.baduk.or.kr/sub01_01.htm?menu=f11 | publisher = Korean Baduk Association | title = History of Korean baduk | access-date = 2008-11-13}}</ref>{{sfn|Fairbairn|2000|p={{page needed|date=May 2014}}}}

The game reached Japan in the 7th century CE—where it is called {{nihongo|'''''go'''''|碁|}} or {{nihongo|'''''igo'''''|囲碁|}}. It became popular at the [[Imperial Court in Kyoto|Japanese imperial court]] in the 8th century,<ref name=HistJapan2>{{Citation|url=http://www.nihonkiin.or.jp/lesson/knowledge-e/history02.htm |publisher=[[Nihon Kiin]] |title=History of Go in Japan: part 2 |access-date=2007-11-02 |url-status=dead |archive-url=https://web.archive.org/web/20071114231818/http://www.nihonkiin.or.jp/lesson/knowledge-e/history02.htm |archive-date=2007-11-14}}</ref> and among the general public by the 13th century.<ref name=HistJapan3>{{Citation|url=http://www.nihonkiin.or.jp/lesson/knowledge-e/history03.htm |publisher=[[Nihon Kiin]] |title=History of Go in Japan: part 3 |access-date=2007-11-02 |url-status=dead |archive-url=https://web.archive.org/web/20071114231823/http://www.nihonkiin.or.jp/lesson/knowledge-e/history03.htm |archive-date=2007-11-14}}</ref> The game was further formalized in the 15th century. In 1603, [[Tokugawa Ieyasu]] re-established Japan's unified national government. In the same year, he assigned the then-best player in Japan, a [[Buddhist]] monk named Nikkai (né Kanō Yosaburo, 1559), to the post of [[Godokoro]] (Minister of Go).<ref name=timeline>{{harvnb|Fairbairn|Hall|2007|loc=''History and Timelines'' "Timeline 1600–1867"}}{{page needed|date=June 2020}}</ref>

Nikkai took the name [[Hon'inbō Sansa]] and founded the [[Hon'inbō]] Go school.<ref name=timeline /> Several [[Four go houses|competing schools]] were founded soon after.<ref name=timeline /> These officially recognized and subsidized Go schools greatly developed the level of play and introduced the [[Go ranks and ratings|dan/kyu style system]] of ranking players.<ref name=ranks>{{harvnb|Fairbairn|Hall|2007|loc=''Articles on Famous Players'' "Honinbo Dosaku"}}{{page needed|date=May 2014}}</ref> Players from the four schools (Hon'inbō, Yasui, Inoue and Hayashi) competed in the annual [[castle game]]s, played in the presence of the [[shōgun]].<ref name=castlegames>{{harvnb|Fairbairn|Hall|2007|loc=''History and Timelines'' "Castle Games 1626–1863"}}{{page needed|date=May 2014}}</ref>
