Queen Elizabeth II is Instagram's new social media star.
The Queen published her first post on Instagram on Thursday, reported CNN. She made the momentous step during a visit to London's Science Museum.
This is her next big step in communication, and it's been a long time coming. Forty-three years after she sent her first email, she took to social media.
However, the Queen wasn't one to send a selfie as her first post. Instead, she shared a letter sent by 19th-century mathematician and computer pioneer Charles Babbage to her grandmother Queen Victoria's husband, Prince Albert.
"Today, as I visit the Science Museum I was interested to discover a letter from the Royal Archives, written in 1843 to my great-great-grandfather Prince Albert," she wrote in the caption.
"Today, I had the pleasure of learning about children's computer coding initiatives and it seems fitting to me that I publish this Instagram post, at the Science Museum which has long championed technology, innovation and inspired the next generation of inventors."
She signed the post "Elizabeth R," which means Elizabeth Regina or Queen Elizabeth.
In a comment on the image, the Science Museum revealed how they felt about having the Queen post for the first time from their museum: "We are honoured that while opening The Smith Centre at the Science Museum Your Majesty shared a post on Instagram for the first time."
They added, "We're thrilled that the image is of correspondence from the Royal Archive between Charles Babbage and Your Majesty's great-great-grandfather Prince Albert about the Difference Engine No.1 on display in our Making the Modern World gallery."
The Queen was visiting the museum to announce its summer exhibition and unveil a new space for supporters. She shared her post with the Britain's royal family millions of followers.
