=== 1966: ITF/Chang Hon-style Taekwondo ===
[[International Taekwon-Do Federation]] (ITF)-style Taekwondo, more accurately known as Chang Hon-style Taekwondo, is defined by [[Choi Hong-hi]]'s ''Encyclopedia of Taekwon-Do'' published in 1983.<ref name="Choi">{{Cite book |last=Choi |first=Hong Hi |title=Encyclopedia of Taekwon-Do |publisher=International Taekwon-Do Federation |year=1983 |asin=B008UAO292}}</ref>

In 1990, the [[Global Taekwondo Federation]] (GTF) split from the ITF due to the political controversies surrounding the ITF; the GTF continues to practice ITF-style Taekwondo, however, with additional elements incorporated into the style. Likewise, the ITF itself split in 2001 and again in 2002 into three separate federations, headquartered in Austria, the United Kingdom, and Spain respectively.<ref>{{cite web|url = https://www.itf-tkd.org/|title = ITF Austria|access-date = January 25, 2020|website = itf-tkd.org|archive-date = October 23, 2020|archive-url = https://web.archive.org/web/20201023030417/https://www.itf-tkd.org/|url-status = live}}</ref><ref>{{cite web|url = http://www.itf-administration.com/|title = ITF United Kingdom|access-date = September 16, 2014|website = Itf-administration.com|archive-date = August 7, 2012|archive-url = https://web.archive.org/web/20120807032337/http://www.itf-administration.com/|url-status = live}}</ref><ref>{{cite web|url = https://www.taekwondoitf.org/|title = ITF Spain|access-date = January 25, 2020|website = taekwondoitf.org|archive-date = January 23, 2020|archive-url = https://web.archive.org/web/20200123042126/https://www.taekwondoitf.org/|url-status = dead}}</ref>

The GTF and all three ITFs practice Choi's ITF-style Taekwondo. In ITF-style Taekwondo, the word used for "forms" is ''[[hyeong|tul]]''; the specific set of tul used by the ITF is called ''Chang Hon''. Choi defined 24 ''Chang Hon'' tul. The names and symbolism of the Chang Hon tul refer to elements of [[History of Korea|Korean history]], culture and religious philosophy. The GTF-variant of ITF practices an additional six tul.{{citation needed|date=August 2023}}

Within the ITF taekwondo tradition there are two sub-styles:
* The style of taekwondo practised by the ITF before its 1973 split with the KTA is sometimes called by ITF practitioners "Traditional Taekwondo", though a more accurate term would be ''Traditional ITF Taekwondo''.
* After the 1973 split, Choi Hong-hi continued to develop and refine the style, ultimately publishing his work in his 1983 ''Encyclopedia of Taekwondo''. Among the refinements incorporated into this new sub-style is the "sine wave"; one of Choi Hong-hi's later principles of taekwondo is that the body's centre of gravity should be raised-and-lowered throughout a movement.

Some ITF schools adopt the sine wave style, while others do not. Essentially all ITF schools do, however, use the patterns (tul) defined in the Encyclopedia, with some exceptions related to the forms ''Juche'' and ''Ko-Dang''.{{citation needed|date=August 2023}}
