How old was Edward VII when he succeeded his mother Queen Victoria to the throne?

Edward VII (Albert Edward; 9 November 1841 – 6 May 1910) was King of the United Kingdom of Great Britain and Ireland from 22 January 1901 until his death in 1910.

The eldest son of Queen Victoria and Prince Albert of Saxe-Coburg and Gotha, Edward was related to royalty throughout Europe. He was heir apparent to the British throne and held the title of Prince of Wales for longer than any of his predecessors. During the long reign of his mother, he was largely excluded from political power, and came to personify the fashionable, leisured elite. He travelled throughout Britain performing ceremonial public duties, and represented Britain on visits abroad. His tours of North America in 1860 and the Indian subcontinent in 1875 were popular successes, but despite public approval his reputation as a playboy prince soured his relationship with his mother.

When Queen Victoria died on 22 January 1901, Edward (aged 59) became King of the United Kingdom, Emperor of India and, in an innovation, King of the British Dominions. He chose to reign under the name of Edward VII, instead of Albert Edward (the name his mother had intended for him to use) declaring that he did not wish to "undervalue the name of Albert" and diminish the status of his father with whom the "name should stand alone".
