At 93, Queen Elizabeth II is the longest-running monarch in British history.
When she dies, it will be the first time the crown has changed hands in over six decades – which, for many people in Britain and the Commonwealth, means it will be the first time in their lifetime they’ll know a monarch other than Queen Elizabeth.
For others within the British royal family, it will signify a move up the line of succession.
Currently, the first person in line for the throne is Prince Charles, who will become King after his mother dies. The Duke and Duchess of Cambridge will then become the Prince and Princess of Wales – a special title since it once belonged to Princess Diana.
There has been much debate about how Camilla, the Duchess of Cornwall’s title will change once her husband becomes King, given that in 2005, Kensington Palace announced she would never be Queen, and would instead be known as Princess Consort if Prince Charles took over the throne.
