Starting in 1870, a Swedish-immigrant colony was established by the State of Maine in Aroostook County. The State of Maine had appointed William W. Thomas, Jr., who had served as American Consul in Sweden during the administration of President Abraham Lincoln, to be State Immigration Commissioner. On March 23, 1870 the Legislature passed an Act authorizing a Board of Immigration and Thomas was named Commissioner of Immigration. Thomas went to Sweden, recruited the first 51 immigrants, and led them into the township that became New Sweden. Early hardships were overcome and the colony prospered and grew into the neighboring townships of Westmanland, Stockholm and the surrounding areas. New Sweden has maintained many Swedish traditions since its founding, including the celebrations of St. Lucia Day and "Midsommar." Founders Day is also observed on July 23 every year. The Swedish language can sometimes still be heard in the older generation. The New Sweden Folk Dancers typically perform at many of the Swedish celebrations and Swedish foods are known to grace the tables. New Sweden was the home of Einar Gustafson, who was the archetype of the child for whom the Jimmy Fund was named.

2003 poisoning
The town made national news headlines in 2003 when a man poisoned the coffee urn at the local Lutheran church, sickening 15 parishioners and killing one. On April 27, 2003, 78-year-old Walter Reid Morrill, known to the town by his middle name, died of arsenic poisoning after drinking coffee at the Gustaf Adolph Lutheran Church in New Sweden, and 15 other, mostly elderly churchgoers became ill, three of them seriously. Five days later, church member Daniel Bondeson, 53, was found after apparently shooting himself in the lower-chest with a rifle, and supposedly leaving a suicide note in which he confessed to having something to do with the poisoning, but the note has never been released to the public. The crime was chronicled in Christine Young's 2005 true crime book A Bitter Brew: Faith, Power, and Poison in a Small New England Town and on the show, Mystery ER, which aired an episode on this incident from the point of view of the youngest victim, then 30 years old.
