The proud new parents Harry decided to mark their anniversary online by posting the shots on their millions of followers on their Instagram account 13 days after birth of their baby son Archie Harrison Mountbatten-Windsor.

The couple, watched by a world audience of millions, exchanged vows at St George’s Chapel, Windsor Castle on May 19 2018 in a joyous public royal occasion.

The couple also posted a special message thanking well-wishers for making big day “even more meaningful” on their Instagram @SussexRoyal, which has now has 8.1 followers.

In an online post, accompanying the montage of 14 wedding snaps, the Palace wrote: "Happy one year anniversary to Their Royal Highnesses, The Duke and Duchess of Sussex!

"Today marks the one year anniversary of the wedding of The Duke and Duchess of Sussex.

"Their Royal Highnesses exchanged vows at St George’s Chapel within the grounds of Windsor Castle on May 19th, 2018.

"The selected song “This Little Light of Mine” was chosen by the couple for their recessional.

"We hope you enjoy reliving this moment, and seeing some behind the scenes photos from this special day.

"Thank you for all of the love and support from so many of you around the world."

The social media post is accompanied by the song This Little Light Of Mine which was chosen by the couple for their recessional on their wedding day.

The pictures feature a series of black and white images by Chris Allerton, including one that appears to be Harry thumbing a lift and another where Meghan is holding hands with her mother Doria Ragland.

The official Royal Family Twitter account posted a message to the Duke and Duchess of Sussex.

Alongside a picture of the couple kissing on the steps of St George's Chapel, the tweet said: "Wishing The Duke and Duchess of Sussex a very happy wedding anniversary.

"Today marks one year since Their Royal Highnesses exchanged vows at St George's Chapel in the grounds of Windsor Castle."

Harry and Meghan have had a momentous 12 months since they wed on May 19 last year at St George's Chapel in a glittering ceremony attended by royalty, celebrities and the public.

Archie's birth came less than a year after the royal wedding in the grounds of Windsor Castle, a wedding attended by A-list stars like Oprah Winfrey and George and Amal Clooney and the British monarchy led by the Queen and the Duke of Edinburgh.

Harry, 34, and Meghan, 37, got engaged following a whirlwind 16-month romance after going on a blind date in London.

A first wedding anniversary is traditionally celebrated with paper gifts - with couples sometimes exchanging presents featuring a paper ticket.

Meghan's mother Doria Ragland - now a grandmother for the first time - is thought to be staying with the couple and could perform babysitting duties if the duke and duchess choose to have a romantic dinner to mark their anniversary.

Archie's birth was registered on Friday, revealing the couple had their baby at London's Portland Hospital, a private hospital favoured by celebrities wanting a money-no-object birthing experience.

The baby, who is the seventh in line to the throne and an eighth great-grandchild for the Queen and Philip, arrived at 5.26am on May 6, weighing 7lb 3oz.

He is believed to be the first mixed-race child born to a senior member of the royal family in centuries, and is a reflection of modern Britain with its culturally diverse population.

The birth certificate also showed Meghan may have been born a commoner but is now a "Princess of the United Kingdom" as far as her occupation was concerned.

When Harry announced to the world his wife had given birth to a boy he could not hide his happiness at becoming a father for the first time, to a baby he said was "absolutely to die for".

The royal baby, who was not given a courtesy title, met his uncle and aunt, the Duke and Duchess of Cambridge, for the first time on Tuesday, having already spent time with his royal great-grandparents, the Queen and Philip.
