"We thank you for your support, and welcome you to our page - Harry & Meghan". The pair attracted one million followers just 6 hours hours after it was created meaning that it broke the record by nearly six hours.
The Duke and Duchess of Sussex shared their very first post on the photo-sharing application. On top of her unbelievable throwback family photos and sweet snaps with husband Jack Brooksbank, Eugenie has also shared the sweetest welcomes to her family members.
"Welcome to our official Instagram".
The debut post also featured several solo shots of the pair, including one of Harry on a military engagement wearing full uniform and one of Meghan greeting well-wishers on Fraser Island, Queensland, last year.
The announcement comes amid the news that Harry and Meghan had split royal households from Prince William and Kate Middleton.
Meanwhile, the most-followed Instagram account in the world is now Instagram itself, followed by footballer Cristiano Ronaldo.
Among all of the photos, there was a previously unseen behind-the-scenes image - right at the very end of the slideshow - from Meghan and Prince Harry's royal tour of Fiji past year.
Meghan, 37, and Harry, 34, unveiled a set of new pictures in their first post with a Royal monogram. It looks like the royal family is starting to up their social media game and fans could not be more pleased, especially since Prince Harry and Meghan Markle have their own account.
