The world got their first glimpse of Archie meeting his great-grandmother Queen Elizabeth and great-grandfather Prince Philip in the history-making photo that also included Meghan's mother, Doria Ragland.

The occasion marked the first time in royal history that a British monarch had been pictured alongside a royal baby's Black grandmother.

Queen Elizabeth boasts a big smile in the groundbreaking photo, while proud first-time grandmother Doria looks on.

Kate Middleton and Prince William also shared a family photo with Archie on their social media account on Friday.

"Wishing Archie a very happy 3rd Birthday today," they shared alongside a photo from Archie's royal christening in July 2019.

The christening took place at Queen Elizabeth's private chapel at Windsor Castle and was attended by around 25 close family members and friends in total, including Meghan's mother Doria Ragland, Prince William and Kate Middleton, and Prince Charles and his wife Camilla, Duchess of Cornwall.
