Elizabeth II is officially an Insta-Queen.
Britain's 92-year-old monarch on Thursday published her first photographs to the verified @theroyalfamily Instagram account from London's Science Museum.
The queen posted two archive images of a letter that Charles Babbage — who is "credited as the world's first computer pioneer," according to the caption — wrote to her great-great-grandfather, Prince Albert, in 1843.
Perhaps Elizabeth realized it was time for a Throwback Thursday, or #TBT, post?
"In the letter, Babbage told Queen Victoria and Prince Albert about his invention the 'Analytical Engine' upon which the first computer programmes were created by Ada Lovelace, a daughter of Lord Byron," the caption says.
The post was signed: "Elizabeth R." Two photographs of the historic social media moment were also shared as an Instagram Story:
Royal aides have previously updated the official royal family Instagram feed with snaps of the queen and relatives meeting dignitaries and attending official functions:
