The Laestadian (See also Laestadianism) church arrived in North America with Nordic (especially Finnish and Sami) immigrants in the latter half of the 19th century, many of whom arrived to work in the copper mines of the Keweenaw Peninsula. Some of these new immigrants found themselves in conflict with older, established immigrants from the same countries, being generally poorer and less established, and hewing to the new, fundamentalist teachings of Lars Levi Laestadius, a Swedish-Sami preacher and botanist born in Arjeplog, Sweden. Laestadian congregations separate from the extant Scandinavian Lutheran churches were formed in Cokato, Minnesota, in 1872 and in Calumet, Michigan, in 1873.
