The situation at the court was complicated as several high ranking personalities were striving for Margaretha, including Lamoral, Count of Egmont. Charles V's son, Crown Prince Philip, arrived at his aunt's court in 1549. Tradition has it that he pursued Margaretha during the few months he was there, though there never could be any official relationship, as she was Lutheran.[4] Three surviving letters from Margaretha to her father show that her health declined steadily over the next few years and she died at the age of 21 in March 1554.[5] In Waldeck chronicles, it was suggested that she had been poisoned. She is likely buried in Brussels where the Place de la Bourse/Beursplein is now located.[1]
Eckhard Sander, in his book Schneewittchen: Märchen oder Wahrheit? (Snow White: Is It a Fairy Tale?), alleged that Margaretha's life was inspiration for the tale of Snow White. Since, however, her father's second wife died in 1546 and he only remarried again in October 1554, her stepmother was not a suspect in the alleged poisoning case. Margaretha's father owned several copper mines; a majority of workers were children. According to Sander, the seven dwarfs were inspired by child labor in the copper mining village Bergfreiheit, now a district of Bad Wildungen that calls itself Schneewittchendorf (Snow White village). Like the fairy tale's dwarfs, the child laborers there used to live in groups of about 20 in a single room house. Sander's theory also worked in the history of Margarethe's brother's children, as well as folktales from the surrounding area - he suggested that the wicked mother figure was taken from the life of Margarethe's niece, and the magnificent wedding from the life of her nephew.[6] Professional folklorists and scholars generally view Sander's theory as unlikely and unconvincing.[7]
