Born in Königsberg, Duchy of Prussia, Peter August became Governor General of Reval (Tallinn), Governor of Estonia, and a Field Marshal in the Russian Imperial Army.[1] He died in Reval, Russian Empire.


He was only the titular duke, because he did not inherit the domain of Haus Beck. It had been inherited by his father's older brother, Duke August (1652–1689), and nephew Frederick William I (1682–1719), and was then sold by the latter's widow to Peter August's older brother, Duke Frederick William II (1687–1749), in 1732.[2] But he re-sold it in 1745 to Baroness Magdalena von Ledebur-Königsbrück. Thus, by the time that Peter August became the head of this cadet branch of the Danish royal dynasty, he was "Duke of Schleswig-Holstein-Sonderburg-Beck" in name only.[2]

He is the male line ancestor of Margrethe II of Denmark, Harald V of Norway and Charles, Prince of Wales.

Marriage and issueEdit

Peter August married Princess Sophie of Hesse-Philippsthal, the daughter of Philip, Landgrave of Hesse-Philippsthal and his wife Countess Katharina Amalie of Solms-Laubach, at Rinteln on 5 September 1723.[1] Sophie died on 8 May 1728 at age thirty-three.[1] Peter August and Sophie had two sons and one daughter:[3]

He married secondly Countess Natalia Nikolaievna Golovina, granddaughter of Count Fyodor Golovin, daughter of Count Nicholas Fedorovich Golovin[3] and his wife Sophie Nikitichna Pushkin, on 15 March 1742.[3] The couple had two sons and one daughter:[3]
