Prince George's last name may surprise you

Does Prince George actually have a last name? The answer is confusing as it is fascinating.

In July 2013, Prince George Alexander Louis of Cambridge made his grand entrance into the world.
The first child of Prince William and Duchess Catherine, Prince George became an overnight icon and the world's ultimate spirit animal thanks to his huge range of hilarious faces and charming antics.
Over the years, we've learnt so much about gorgeous George.
We know he wants to be a police officer when he grows up, that he can speak Spanish and he's taking after his creative mum Kate with his artistic eye.
But one riddle that remains is as mysterious as the crown jewels....

What is Prince George's last name?

Behind palace gates, he's known as Prince George Alexander Louis of Cambridge but when he's at school at Thomas's Battersea in London, Prince George of Cambridge has adopted Prince William's territorial title for his schooling and is known as George Cambridge to his peers.
The four-year-old even showed off his surname on his first day of school when a sticker on his backpack bearing his name was spotted!
Can you spot it? The label on the royal's school bag reads "George Cambridge."
The third in line to the British throne is following in the footsteps of his dad Prince William and uncle Prince Harry.
In high school Prince Charles' sons were known as William Wales and Harry Wales, taking on their father's territorial title from the Prince of Wales.
This was because they were unmarried and hadn't yet been given their titles of the Duke of Cambridge and the Duke of Sussex.
If George one day marries, he will be given a new royal title and style to reflect this union.
George Cambridge has a lovely ring to it.
While Prince William and Duchess Catherine may have chosen this name for George's schooling, according to the official Royal Family website George's official last name is Mountbatten-Windsor.
On a web page titled 'The Royal Family name' it states: "Unless The Prince of Wales chooses to alter the present decisions when he becomes king, he will continue to be of the House of Windsor and his grandchildren will use the surname Mountbatten-Windsor.
Trying to crack the royal surname code is a complicated process.

How do royal surnames work?

According to the official Royal Family website, members can either choose from two options and be known "both by the name of the Royal house, and by a surname, which are not always the same. And often they do not use a surname at all."
In fact before 1917, royals didn't even have surnames and were simply known by their house or dynasty.
The most common surname for the royal's was Saxe-Coburg-Gotha, which was used for several European sects. But in 1917 King George V decided to axe this Germanic title to move the royal family away from German ties and instead they adopted the title of Windsor.

"George V specifically adopted Windsor, not only as the name of the 'House' or dynasty, but also as the surname of his family. The family name was changed as a result of anti-German feeling during the First World War, and the name Windsor was adopted after the Castle of the same name," the Royal Family website states of the decision.
In 1960, The Queen and Prince Philip decided they wanted a special title for their children and grandchildren to distinguish them from their other relatives and came up with Mountbatten-Windsor, which is a combination of The Queen and Prince Philip's surnames.
No royal titles to see here, William and Kate's kids will use "Cambridge" as their surname at school.
So for example, Prince Harry can go by his territorial title Prince Harry, Duke of Sussex, or roll with the family's surname Henry Charles Albert David Mountbatten-Windsor, it all just depends on the context.

Why doesn't Prince George need a surname?

When you're a key player of the world's most famous family, you're so damn well-known you really don't need a surname.
Essentially, you're the regal version of Madonna.
Another tradition that has also stuck is for royals to only sign their first names.
As their website explains: "Kings and princes were historically known by the names of the countries over which they and their families ruled. Kings and queens therefore signed themselves by their first names only, a tradition in the United Kingdom which has continued to the present day."
The face you make when you realise you don't really need a surname!
