Frederik VIII (Danish: Christian Frederik Vilhelm Carl; 3 June 1843 – 14 May 1912) was King of Denmark from 29 January 1906 until his death in 1912.
As the eldest son of King Christian IX, nicknamed "the father-in-law of Europe", Frederick was related to royalty throughout Europe. He was heir apparent to the Danish throne and served as crown prince for more than 42 years. During the long reign of his father, he was largely excluded from influence and political power.
