Ряння жизнь
Фредерик родился в Кристианборге в Копенгагене 11 октября 1753. Для обеспечения своего положения, at the age of 3 он был выбран coadjutor in the Prince-Bishopric of L?beck. This meant that in time he would succeed the Prince-Bishop then in office, Frederick August. This plan had to be abandoned, however, and Frederick stayed in Denmark as a junior member of the royal family.
