He is the Queen's youngest son and is currently the only one not to have the title of a Duke.
But it appears that Prince Edward may have been offered the title currently held by Prince William - but instead opted for his current title Earl of Wessex after hearing about it in a movie.
It is customary for royals to be given new titles on their wedding day and some eyebrows were raised when it was announced in 1999 that Edward and wife Sophie would be known as the Earl and Countess of Wessex.
However, according to one courtier, he was originally going to be offered the title Duke of Cambridge but asked to be Earl of Wessex after the character in the movie Shakespeare in Love.
The courtier told The Telegraph in 2010: "Prince Edward was going to be the Duke of Cambridge, but he watched the film Shakespeare in Love, which had a character called the Earl of Wessex.
"He liked the sound of it and asked the Queen if he could have that instead."
However, E dward is set to eventually get the title of a duke - although it will be when his older brother Charles becomes King. And that the title will be Duke of Edinburgh.

It was announced at the time of Edward's wedding in 1999 he would one day succeed his father as the Duke of Edinburgh with the blessing of the late Prince Philip and the Queen.
Sophie, currently the Countess of Wessex, will eventually become the Duchess of Edinburgh - a courtesy title which was held by the Queen - when that happens.
Today, Edward appeared at the Church of England's national assembly, where he read an address on behalf of the Queen.
Her Majesty had been due to attend the event, but her appearance was cancelled last week after being ordered to rest following a night in hospital last month.
Edward, who read the 95-year-old head of state's speech to bishops and clergy at Church House, the Westminster headquarters of the Church of England, praised the institution for offering "hope" during the pandemic.
Before the speech, he said the Queen sends her "sincere and deep apologies that she cannot be here today".
Edward added: "I think you probably understand why, and she regrets that deeply."
It is the first time the monarch, who is Supreme Governor of the church, has missed her five-yearly visit to the Synod in its 51-year history.
