During this period the journey of Leif Ericson to Vinland (North America) was being widely discussed and there was renewed interest in the Vikings throughout Scandinavia, stirred by the National Romanticism movement. Five years earlier Norway had participated in the World's Columbian Exposition by sending the "Viking", a replica of the "Gokstad ship", to Chicago. There was also friction between Sweden and Norway (which ultimately led to Norway's independence from Sweden in 1905). Some Norwegians claimed the stone was a Swedish hoax and there were similar Swedish accusations because the stone references a joint expedition of Norwegians and Swedes. It is thought to be more than coincidental that the stone was found among Scandinavian newcomers in Minnesota, still struggling for acceptance and quite proud of their Nordic heritage.
