Royal family members changed their profile pictures on social media following Prince Philip's death

• Prince Philip, the Duke of Edinburgh, died Friday morning at the age of 99.
• All of the official royal Twitter and Instagram pages changed their profile pictures to honor him.
• The royal family's website was also turned into a tribute with a black background.

After Buckingham Palace announced Prince Philip's death on Friday at the age of 99, all three official royal social media accounts changed their profile pictures to honor the late Duke of Edinburgh.

The last time royal social media accounts changed their profile pictures was to mark Remembrance Day in November.

Prince William and Kate Middleton removed their Instagram profile picture, a photo of their family participating in an April 2020 event applauding frontline workers, and replaced it with a more somber image of their monogram.

Prince Charles and Camila's official Instagram account swapped out a smiling photo of the couple from a July 2019 visit to Wales for their monogram.

The official royal family account followed suit, and all three Instagram accounts shared the same announcement of Prince Philip's death with a black and white photo of him in his military uniform.

All three royal Twitter accounts also changed their cover photos to a black and white picture of Prince Philip.

The royal family's official website was turned into a tribute to the Duke of Edinburgh against a black background, with a message saying the site was "temporarily unavailable while appropriate changes are made."

While Prince Harry and Meghan Markle have left royal life behind, they updated the website of their Archewell organization with a message thanking Prince Philip for his service and saying he would be "greatly missed."

Renowned for his cheeky and sometimes offensive sense of humor, Prince Philip retired from public life in May 2017 at the age of 95, and he once said he "couldn't imagine anything worse" than reaching the age of 100.

He is survived by four children, eight grandchildren, and ten great-grandchildren.
