The Queen will mark the 70th year of her reign in 2022 having ascended the throne at the age of 25 in 1952. But when the young Princess Elizabeth became monarch, she was asked by Martin Charteris, her private secretary at the time, what she wanted her regnal name to be – and her response was very matter-of-fact.
The new Queen's response was: "My own of course."
Since ancient times, some monarchs have chosen to use a different name from their original name when they accede to the monarchy.

Elizabeth's father was born Albert Frederick Arthur George, but when he became monarch in 1936, he chose the name King George VI in honour of his own father, King George V.
