Prince William Shares Sweet Photo of Princess Diana on Instagram

Prince William’s official Instagram account recently shared the sweetest photo in honor of his late mother, Princess Diana. The post had another meaning as well in honor of 999 Day, which is a day of celebration for emergency service personnel including police, fire, and medical services. Prince William shared several photos of himself in the post. The first one, however, has a lot of meaningful memories behind it.

Today marks #999DayUK, when we celebrate and say thank you to our incredible Police, Fire and Emergency Medical services ‍♀‍‍⚕ and all our specialised emergency services for all that they do to keep us safe. The first photograph in this post is of The Duke of Cambridge and The Duke of Sussex and their mother Diana, Princess of Wales, with their cousins Peter Phillips and Zara Tindall in the yard of the Old Fire Station in the grounds of Sandringham House in 1988. On 999 Day later today The Duke will visit @TheFirefightersCharity at Harcombe House in Devon to hear about the support that the centre provides to members of the fire and rescue service and their families, and meet representatives from across the emergency services sector. On the extraordinary work of our emergency services, The Duke of Cambridge said: "As a society, we owe our wellbeing, and indeed our lives, to the men and women in our emergency services who work tirelessly to protect us in some of the most difficult circumstances. It is only fitting that we should recognise the vital role that they play, and pay tribute to the bravery and dedication of those who have made the ultimate sacrifice for their communities." 999 Day begins annually at 9am on the 9th September (the 9th hour of the 9th day of the 9th month) and is held to pay tribute to the invaluable work that is carried out by the emergency services and responders.

The Princes honor their mother on social media

This isn’t the first time the Princes have paid tribute to their mother on social media. Another sweet photo posted by Prince William shows himself, his mother, and Prince Harry doing their part at a local homeless charity.

“The Duke of Cambridge has today become Patron of homeless charity The Passage – here His Royal Highness is pictured with The Duke of Sussex and their mother Diana, Princess of Wales, in an early visit to @passagecharity,” the post is captioned.

The Duke of Sussex shares an inspirational quote from Princess Diana

The Duke and Duchess of Sussex have also shared a tribute to Diana on Instagram. They shared an inspirational quote that Princess Diana once said. “Carry out a random act of kindness, with no expectation of reward, safe in the knowledge that one day someone might do the same for you,” Diana is quoted as saying.

“Words have the power to inspire, which is why we’re happy to share some of our favourite quotes,” the caption reads. “From members of the public to public figures, from teachers and students to young leaders, we begin with a quote from Diana, Princess of Wales.”

Princess Diana was killed in a tragic car accident in Paris on August 31, 1997. Dodi Fayed, her boyfriend, along with the driver, were found dead at the scene. Diana would die a few hours later at a local hospital from her injuries at only 36 years old.

She is still dearly missed to this day. Her sons honor her in different ways all the time and they have also stayed true to her good and charitable nature. Millions still mourn the loss of Diana, the Princess of Wales.
