What is Prince Louis's title?

Prince Louis Arthur Charles was born on April 23, 2018.

He is Princess Kate and Prince William's third child and was born at St Mary's Hospital in Paddington, London.

In a statement, Kensington Palace said: "Her Royal Highness The Duchess of Cambridge was safely delivered of a son at 1101hrs. The baby weighs 8lbs 7oz.

"The Duke of Cambridge was present for the birth.

"Her Royal Highness and her child are both doing well."

However, the public had to wait four more days before the royal couple revealed the tot's name and title.

Kate and Prince William's youngest child held the title His Royal Highness Prince Louis of Cambridge.

However after the death of his great-grandmother The Queen, the young prince became His Royal Highness Prince Louis of Wales.

This was because his dad Wills became Prince of Wales when Prince Charles became King.

Another title he bears is His Royal Highness Prince Louis of the United Kingdom of Great Britain and Northern Ireland.

Why did William and Kate name their son Louis?

As with most royal names, Prince Louis' one comes with a poignant meaning.

he name Louis originates from France and Germany and means "famous warrior' or "famous in battle".

Louis is one of his father Prince William's own middle names.

It is also one his older brother George's middle name.

It was chosen by his father King Charles as tribute to his late mentor, Lord Louis Mountbatten.

The Earl was murdered in 1979 by an IRA bomb which was planted on his fishing boat during an outing with his family in County Sligo, Ireland.

Speaking shortly after Louis' birth, editor of Majesty magazine Joe Little said of his name: "I am a bit surprised, actually.

"We all seem to have missed Louis, when we were thinking Arthur or Albert or James.

"We didn't consider it because it's George's middle name, and William's middle name, and I just didn't think William and Kate would recycle a name they had used for their first-born.

"I didn't think it would be Albert, as that doesn't pass the modern playground test."
