In 1516, King Christian II, on the advice of his Dutch-born mother Sigbrit, summoned 80 members from Holland and let them settle in St. Magleby and the surrounding area with the obligation that they would "supply Copenhagen Castle with the necessary roots and onions". Later, these skilled gardeners mixed with the other inhabitants of the island, almost all of whom adopted their customs and traditions, as well as their peculiar folk costumes.
