- Duke Frederick VIII (Danish: Frederik Christian August af Slesvig-Holsten-Sønderborg-Augustenborg; German: Friedrich Christian August Herzog von Schleswig-Holstein-Sonderburg-Augustenburg) (July 6, 1829 – January 14, 1880) was the German pretender to the throne of Schleswig-Holstein from 1863, although in reality Prussia took overlordship and real administrative power.
He was the eldest son of Christian August II, Duke of Schleswig-Holstein-Sonderburg-Augustenburg and Countess Louise Sophie of Danneskiold-Samsøe. He was ethnically perhaps the most Danish Prince of the Danish Royal dynasty in his generation (at the time of Denmark's most recent succession crisis).
Frederick VIII(Danish: Christian Frederik Vilhelm Carl; 3 June 1843 – 14 May 1912) was King of Denmarkfrom 1906 to 1912. Before his accession to the throne at age 62, he served as crown princefor over 42 years. During the long reign of his father, King Christian IX, he was largely excluded from influence and political power.
In November 1863 Frederick claimed the twin-duchies in succession after the death without a male heir of King Frederick VII of Denmark, who was also the Duke of Schleswig and Holstein. As Holstein was inherited after the salic law among descendants of Helwig of Schauenburg , the independence movement had long nourished hopes that the king's death would lead to their goal.
Duke Frederick VIII (_de. Friedrich Herzog von Schleswig-Holstein-Sonderburg-Augustenburg; July 6, 1829 - January 14, 1880), claimed to be the Duke of Schleswig-Holstein from 1863, though almost nominally, as Prussia actually took overlordship and real administrative power.
