Editing Origami (section)

====Since 1800s====
When Japan opened its borders in the 1860s, as part of a modernization strategy, they imported Fröbel's Kindergarten system—and with it, German ideas about paperfolding. This included the ban on cuts, and the starting shape of a bicolored square. These ideas, and some of the European folding repertoire, were integrated into the Japanese tradition. Before this, traditional Japanese sources use a variety of starting shapes, often had cuts, and if they had color or markings, these were added after the model was folded.<ref>"History of Origami in the East and West before Interfusion", by Koshiro Hatori. From Origami^5, ed. Patsy Wang Iverson et al. CRC Press 2011.</ref> In Japan, the first kindergarten was established in 1875, and origami was promoted as part of early childhood education. The kindergarten's 1877 regulations listed 25 activities, including origami subjects. ''Shōkokumin'' (小国民), a magazine for boys, frequently published articles on origami. ''Origami Zusetsu'' (折紙図説), published in 1908, clearly distinguished ceremonial origami from recreational origami. These books and magazines carried both the traditional Japanese style of origami and the style inspired by Fröbel.<ref name="kyushu4">{{cite web|url=https://guides.lib.kyushu-u.ac.jp/origami/moderntimes|archive-url=https://web.archive.org/web/20210507225636/https://guides.lib.kyushu-u.ac.jp/origami/moderntimes|script-title=ja:折り紙の歴史と現在: 明治・大正|language=ja|publisher=Kyushu University Library|archive-date=7 May 2021|access-date=14 November 2022}}</ref>

In the early 1900s, [[Akira Yoshizawa]], [[Kosho Uchiyama]], and others began creating and recording original origami works. Akira Yoshizawa in particular was responsible for a number of innovations, such as [[wet-folding]] and the [[Yoshizawa–Randlett system|Yoshizawa–Randlett diagramming system]], and his work inspired a renaissance of the art form.<ref>{{cite web|url=https://www.nytimes.com/2005/04/02/arts/design/akira-yoshizawa-94-modern-origami-master-dies.html|title=Akira Yoshizawa, 94, Modern Origami Master, Dies|author=Margalit Fox|work=[[The New York Times]]|date=April 2, 2005}}</ref>

In 1974, origami was offered in the USSR as an additional activity for elementary school children.<ref>И. С. Могилевская. Складывание из бумаги // журнал "Начальное образование", № 7, 1974. стр.39</ref>

During the 1980s a number of folders started systematically studying the mathematical properties of folded forms, which led to a rapid increase in the complexity of origami models.<ref>Lang, Robert J. "Origami Design Secrets" Dover Publications, 2003.</ref>

Starting in the late 20th century, there has been a renewed interest in understanding the behavior of folding matter, both artistically and scientifically. The "new origami," which distinguishes it from old craft practices, has had a rapid evolution due to the contribution of computational mathematics and the development of techniques such as ''box-pleating'', ''tessellations'' and ''wet-folding''. Artists like [[Robert J. Lang]], [[Erik Demaine]], [[Sipho Mabona]], [https://giangdinh.com Giang Dinh], [http://www.origami-artist.com Paul Jackson], and others, are frequently cited for advancing new applications of the art. The computational facet and the interchanges through social networks, where new techniques and designs are introduced, have raised the profile of origami in the 21st century.<ref>{{cite web |last1=Gould |first1=Vanessa |title=Between the Folds, a documentary film |url=https://www.vanessagould.com}}</ref><ref>{{cite book |last1=McArthur |first1=Meher |title=Folding Paper: The Infinite Possibilities of Origami |date=2012 |publisher=Tuttle Publishing |isbn=978-0804843386}}</ref><ref>{{cite book |last1=McArthur |first1=Meher |title=New Expressions in Origami Art |date=2020 |publisher=Tuttle Publishing |isbn=978-0804853453}}</ref>
