Members of the Royal Family 's official titles date back centuries, with Monarchs handing down honours and dukedoms for generations.
Whether it's a title that shows a position in terms of the line of succession, like the The Prince of Wales, or a wedding Dukedom like the Duke and Duchess of Cambridge, there are a whole host for them to choose from.
Things will change completely when Prince Charles takes the throne, and one of his early jobs will be to allocate some of the changing titles out among his loved ones.
The Queen has 12 great-grandchildren - the eldest being Savannah Phillips all the way down to baby Sienna Mapelli Mozzi - and three of them will carry several different titles in their lifetimes, some of which carry huge historical and political importance.
While Prince George and Prince Louis will eventually take on some important senior royal titles, their sister Princess Charlotte is expected to carry a title that has significant ties to royal history.
Princess Charlotte Elizabeth Diana was born on May 2, 2015, at St Mary’s Hospital in Paddington, London and lives with her family in Apartment 1A of Kensington Palace.
The family will soon be making a highly-anticipated move to the Windsor Estate where they will likely live in the humble Adelaide Cottage.
The princess's current and official title is Her Royal Highness Princess Charlotte Elizabeth Diana of Cambridge, and she sits fourth in line to the throne. But this will all change when her grandfather becomes the king.
When Prince Charles is on the throne, Prince William will likely become The Prince of Wales. Before he has his official Prince of Wales ceremony at Caernarfon Castle, Charlotte will be known as HRH Princess Charlotte of Cornwall and Cambridge.
The addition of Cornwall to the title comes from the most senior Dukedom which is held by the Prince of Wales. Following Prince William’s official ceremony, Princess Charlotte and her brothers will become Prince George, Princess Charlotte and Prince Louis of Wales.
But looking even further ahead into the future, Princess Charlotte would be in line to inherit a historic title when Prince William is king.

The Princess Royal is typically the eldest daughter of the monarch and it works in much the same way as the Prince of Wales title for both senior and high-ranking members of the Royal Family.
There have only been seven Princess Royals, the inaugural of whom was Princess Mary, the eldest daughter of King Charles I and Queen Henrietta Maria.
Following Princess Mary, the other Princess Royals include Princess Louisa Maria (daughter of King James II and VII), Princess Anne (King George II), Princess Charlotte (King George III), Princess Victoria (Queen Victoria), Princess Louise (King Edward VII), Princess Mary (King George V) and Princess Anne (Queen Elizabeth II).
While the rights of primogeniture do come into play, the inheritance of the title is not guaranteed if the previous holder is still alive.
When King George V died his daughter Mary was still the Princess Royal, meaning that when King George VI came to the throne his daughter Princess Elizabeth, now Queen Elizabeth, could not inherit the title even though she would have been eligible to hold it.
Unlike other styles, when the Princess Royal dies the title is not automatically inherited by her eldest daughter, it instead goes back to the monarch to bestow it upon their own daughter, if they have one.
As Prince Charles has no daughters, it is likely the Princess Royal title will be held in suspension once Princess Anne passes away, but will be re-granted to Princess Charlotte once her father becomes king.
But Charlotte isn't the only one of the Cambridge children who will see a major title change in their future. When Prince William is on the throne, Prince George will be eligible to become The Prince of Wales - making him the 28th incumbent.
