, 1826 Since her father had no surviving legitimate sons, Vilhelmine Marie was a very desirable bride. Among her suitors was the future
Oscar I of Sweden of the newly established
Bernadotte dynasty. On 28 May 1826, she was
engaged to her second cousin,
Prince Frederick of Denmark, the future King Frederick VII, who was a direct male-line descendant of King
Frederick V through his second wife, Queen
Juliana Maria of Brunswick-Wolfenbüttel. The engagement was very popular as it united the two lines of the Royal House, which had been in a strained relationship since 1814. , 1831 The couple were married on 1 November 1828 by the royal
confessor Jacob Peter Mynster at the chapel of
Christiansborg Palace in
Copenhagen. The public celebrations were unusually vivid, with illuminations, poems, public festivities, and a foundation, Vilhelmine-Stiftelsen, for the benefit of providing brides with suitable equipment. The Danish play ''
Elves' Hill'' () was commissioned by the King for the wedding and premiered on 6 November 1828. It became evident, however, that the marriage was disastrous and unhappy: Frederick's debauched lifestyle, full of infidelity and heavy drinking, was said to have deeply hurt the 'female feelings' of the princess, who, being good hearted and mild, lacked character and influence over her husband. Her unhappy marriage concerned her parents, who felt sorry for her. The couple separated in 1834 and divorced in 1837. ==Second marriage==
