Peter II (German:Nikolaus Friedrich Peter) (8 July 1827 – 13 June 1900) was the reigningGrand Duke ofOldenburg from 1853 to 1900. He claimed hereditary parts ofDuchy of Holstein after theSecond Schleswig War in 1864. After signing a treaty on 23 February 1867 inKiel, he renounced his claims. In return, he received the district ofAhrensbök and the Prussian parts of the former Principality ofLübeck other than the village ofTravenhorst, and was given a million taler as compensation from Prussia. Thus the Grand Duchy of Oldenburg gained access to theBaltic Sea.
Duke Nikolaus FriedrichPeter was the only son ofAugustus, Grand Duke of Oldenburg by his second wifePrincess Ida of Anhalt-Bernburg-Schaumburg-Hoym. He was born on 8 July 1827 in Oldenburg.[1]
In his youth, he served as a General of Cavalry in the Prussian army. He also served as General of Infantry in theHanoverian Army.[1]
On 10 February 1852, Peter marriedPrincess Elisabeth of Saxe-Altenburg.[2] She was the fourth daughter ofJoseph, Duke of Saxe-Altenburg andAmelia of Württemberg, and was a sister ofQueen Marie of Hanover andGrand Duchess Alexandra Iosifovna of Russia.
They had two sons,Frederick Augustus (born in 1852) and George (born in 1855). Peter II may have had an illegitimate son, Peter Altmann (Rastede 1857-Brighton 1934), married and had issue.
He succeeded his father as Grand Duke in 1853.[3] Peter ruled over a population of roughly 800,000.[3]
Peter's family had ties to the Russian imperial family (both were descendants ofChristian Albrecht of Holstein-Gottorp), so that he sided with Russia against Austria during theCrimean War. During theFirst Schleswig-Holstein War, he laid claim to part of the territories seized by Prussia, but in 1866 ceded his claim to the duchies.[1] The following year, he created a military compact with Prussia, in which his troops were incorporated into the corps ofPrince Frederick Charles of Prussia during theFranco-Prussian War.[1]
In 1896, his wife Elisabeth died.[2] She died a year after their daughter-in-lawElisabeth Anna.
After he suffered from heart trouble resulting from overwork, Peter's physicians recommended he have a long trip abroad.[4] He died the following year, on 13 June 1900 at his summer residence inRastede.[1] He was succeeded as Grand Duke by his eldest son,Frederick Augustus.
