On July 6, 1744, Luise Ulrike, princess of Prussia, sister of Fredrik II married by proxy the crown prince of Sweden, Adolf Friedrich of Holstein-Gottorp in Berlin. She was twenty-four years of age.
Luise Ulrike’s bridal journey began shortly after her proxy wedding. She left Berlin in July 1744 and reached Stockholm in late August 1744. We are well informed about this jouney thanks to the numerous letters the princess wrote to her family. Most of these letters have been published by Fritz Arnheim.
