[[File:Interior of the Oude kerk in Amsterdam (south nave), by Emanuel de Witte.jpg|thumb|upright=1.2|Early Calvinism was known for simple, unadorned churches as depicted in this 1661 portrait of the interior of the [[Oude Kerk, Amsterdam]].]]
Although much of Calvin's work was in [[Geneva]], his publications spread his ideas of a correctly Reformed church to many parts of Europe. In Switzerland, some cantons are still Reformed, and some are Catholic. Calvinism became the dominant doctrine within the [[Church of Scotland]], the [[Dutch Republic]], some communities in [[Flanders]], and parts of Germany, especially those adjacent to the Netherlands in the [[Palatinate (region)|Palatinate]], [[Kassel]], and [[Lippe]], spread by [[Caspar Olevian]] and [[Zacharias Ursinus]] among others. Protected by the local nobility, Calvinism became a significant religion in eastern Hungary and Hungarian-speaking areas of [[Transylvania]]. {{as of|2007}}, there are about 3.5 million Hungarian Reformed people worldwide.<ref name="The Reformed Church">{{cite web |title=The Reformed Church |url=http://www.bocskaihall.org.au/reformed-church.htm |publisher=Hungarian Reformed Church of Australia |access-date=8 February 2014  |archive-url=https://web.archive.org/web/20140222135525/http://www.bocskaihall.org.au/reformed-church.htm |archive-date=22 February 2014}}</ref>

Calvinism was influential in France, Lithuania, and Poland before being mostly erased during the [[Counter-Reformation]]. One of the most important Polish reformed theologists was Łaski, who was also involved into organising churches in [[East Frisia]] and [[Stranger churches|Stranger's Church]] in London.<ref>{{Cite journal |last1=Eaves |first1=Richard Glen |last2=Carter |first2=William A. |date=1979 |title=John à Lasco: A Polish Religious Reformer in England, 1550–1553 |journal=Journal of Thought |volume=Journal of Thought |issue=14 |pages=311–323|jstor=42588808 }}</ref> Later, a faction called the [[Polish Brethren]] broke away from Calvinism on January 22, 1556, when [[Piotr of Goniądz]], a Polish student, spoke out against the doctrine of the [[Trinity]] during the general synod of the Reformed churches of Poland held in the village of [[Secemin]].<ref>{{Cite book |last=Hewett |first=Phillip |title=Racovia: An Early Liberal Religious Community |publisher=Blackstone Editions |year=2004 |isbn=978-0-9725017-5-0 |pages=21–22}}</ref> Calvinism gained some popularity in [[Scandinavia]], especially Sweden, but was rejected in favor of Lutheranism after the [[Synod of Uppsala]] in 1593.<ref name="Vlib.iue.it">{{cite web |url=http://vlib.iue.it/carrie/texts/carrie_books/gilbert/12.html |title=The Reformation in Germany And Scandinavia |publisher=Vlib.iue.it |access-date=5 December 2013 |archive-date=19 February 2015 |archive-url=https://web.archive.org/web/20150219195346/http://vlib.iue.it/carrie/texts/carrie_books/gilbert/12.html |url-status=dead }}</ref>

Many 17th century European settlers in the [[Thirteen Colonies]] in [[British America]] were Calvinists, who emigrated because of arguments over church structure, including the [[Pilgrims (Plymouth Colony)|Pilgrim Fathers]]. Others were forced into exile, including the French [[Huguenots]]. Dutch and French Calvinist settlers were also among the first European colonizers of South Africa, beginning in the 17th century, who became known as [[Boers]] or [[Afrikaner Calvinism|Afrikaners]].

Sierra Leone was largely colonized by Calvinist settlers from Nova Scotia, many of whom were [[Black Loyalist]]s who fought for the [[British Empire]] during the [[American Revolutionary War|American War of Independence]]. [[John Marrant]] had organized a congregation there under the auspices of the [[Countess of Huntingdon's Connexion|Huntingdon Connection]]. Some of the largest Calvinist communions were started by 19th- and 20th-century [[missionary|missionaries]]. Especially large are those in Indonesia, Korea and Nigeria. In South Korea there are 20,000 [[Presbyterianism|Presbyterian]] congregations with about 9–10 million church members, scattered in more than 100 Presbyterian denominations. In South Korea, Presbyterianism is the largest Christian denomination.<ref name="Chris Meehan">{{cite web |author=Meehan |first=Chris |date=4 October 2010 |title=Touched by Devotion in South Korea |url=http://www.crcna.org/news-and-views/touched-devotion-south-korea |archive-url=https://web.archive.org/web/20170709093000/https://www.crcna.org/news-and-views/touched-devotion-south-korea |archive-date=9 July 2017 |access-date=5 December 2013 |publisher=Christian Reformed Church}}</ref>
