Friedrich August, Duke of Holstein-Oldenburg (20 September 1711 in Gottorp, Schleswig – 6 July 1785 in Oldenburg) was the son of Christian August, Duke of Holstein-Gottorp and his wife Margravine Albertine Friederike of Baden-Durlach.
Marriage and issue
Frederick Augustus married on 21 November 1752 to Princess Ulrike Friederike Wilhelmine of Hesse-Kassel; the couple had three children:
- Peter Friedrich Wilhelm, Duke of Oldenburg (3 January 1754 – 2 July 1823)
- Luise of Holstein-Gottorp-Oldenburg (2 October 1756 – 31 July 1759)
- Hedwig Sophie Charlotte of Holstein-Gottorp-Oldenburg (22 March 1759 – 20 June 1818)
Titular History
Empress Catherine the Great of Russia, on behalf of her son Paul of Russia, last of the Dukes of Holstein-Gottorp, ceded the lands of that duchy to Denmark. In exchange, Denmark ceded the Duchy of Oldenburg to the Prince Bishops of Lübeck, a cadet branch of the Dukes of Gottorp. Thus, Friederich August of Holstein-Gottorp, Prince Bishop of Lübeck, became Duke of Oldenburg.
His son and heir apparent, Peter Friedrich Wilhelm, succeeded him as Wilhelm I, Duke of Oldenburg.
