Elizabeth became Queen in 1852 and was already a mum of two to Charles, born in 1948, the year after her wedding, and Anne two years later in 1950.
The late monarch and her eldest son shared a close bond as he was the first in the line of succession. However, the pair didn't always agree.
In Kate Nicholl's new book 'The New Royals', she delved into their relationship and revealed a time the late Queen overruled her son.
