Princess Eugenie recently paid tribute to the most important women in her life on International Women’s Day.

On her Instagram account, the 28-year-old princess uploaded some throwback photos of herself with Sarah Ferguson, Queen Elizabeth II, and Princess Beatrice.

“Let’s celebrate amazing women today and every day, like my sister Beatrice… You are pretty amazing Bea and we celebrate you on #iwd2019 #iwd,” she captioned the first photo of Princess Beatrice via Instagram Story.

Princess Eugenie also shared a photo of Princess Beatrice and Ferguson taken during her wedding to Jack Brooksbank on Oct. 12, 2018.

“We have the will to create whole-of-society, collaborative and integrated responses to make sure half of us are not held back or left behind,” she captioned the second photo.

Princess Eugenie then shared an adorable photo of herself with Princess Beatrice and Ferguson, which was taken when they were still very young. In her caption, Princess Eugenie said that she is celebrating her mom and called Ferguson cool.

In her last post, Princess Eugenie shared a picture of Her Majesty during her recent visit to the Science Museum in London last week. The Queen sent out her first Instagram post during her visit to the museum.

Princess Eugenie was not the only member of the royal family to honor their relatives and friends during this year’s International Women’s Day. Ferguson also uploaded photos of her daughters and Princess Diana on her Instagram account.

Ferguson remembered Princess Diana as one of her dearly departed friends who she considers strong. The mom of two also included a black and white photo of her daughters in her post.

The Duchess of York is close to her daughters and even to her ex-husband Prince Andrew. In fact, their amicable relationship as a divorced couple has led fans to think that there is a possibility for them to get married again one day.

Prince Andrew and Ferguson divorced in 1996 and the latter said that they do not have plans to get married again.
