The idea of arranging an annual gathering for Danish-Americans in a moorland setting in Denmark originated with Danish immigrant Max Henius.
Funds were raised by Danish Americans to purchase to 200 acres (0.81 km2) of heather-covered hills and moorland, located within Denmark's largest forest, Rold Forest (Danish: Rold Skov).
Henius also required it to serve as the venue for annual Fourth of July celebrations.
[4] Every July 4 since 1912, except during the two world wars and the COVID-19 pandemic, large crowds have gathered in the heather-covered hills of Rebild to celebrate American Independence Day.
Due to a period of national mourning caused by King Frederik VIII's sudden death in May 1912, the first Rebild Festival was delayed until August 5.
