border gate, thus gaining entry into her native Sweden. In Sweden she stayed at first at a tourist hotel in Sälen, before travelling on to Stockholm where her parents and relatives lived. Her presence in Sweden became problematic where some considered her presence to put Sweden's neutrality in jeopardy. President Roosevelt then offered her a personal invitation to the United States. Her uncle, King Gustav V of Sweden, telegraphed her father-in-law King Haakon and advised against the trip, but Märtha insisted on accepting the invitation. Roosevelt sent the US Army transport to the then Finnish port city of Petsamo to pick her up. In the U.S., she and her children initially stayed at the White House.

Thus the Norwegian royal couple, like many other couples during that time, were separated for much of the war.

Princess Märtha spent much of World War II in the United States, where she worked tirelessly to keep up support for Norway among the American public and government. Trygve Lie wrote about her war-work: “During those
