WILL AND HARRY'S CONCERT FOR DIANA
Just one month before the 10-year anniversary of their mother's death (and on what would have her 46th birthday) Prince William and Prince Harry hosted a concert at London's Wembley Stadium in Princess Diana's honor. The Concert for Diana featured performances from Elton John and Kanye West and others along with speeches from big names like Bill Clinton, Nelson Mandela and David Beckham. The event was – and still is – the largest public memorial event for Diana since her funeral.

When Prince William and the then-Kate Middleton revealed their engagement in 2010, all eyes were on the familiar rock on Kate's left ring finger. The 12-carat oval sapphire encircled with 14 solitaire diamonds is the same one Prince Charles gave to Diana in 1981.
During the couple's official engagement interview, William said that he chose the ring to keep Diana a part of the experience. "Obviously she's not going to be around to share any of the fun and excitement of it all – this was my way of keeping her close to it all."

WILL AND KATE'S WEDDING
From the flowers to the venue, William and Kate's 2011 wedding was literally brimming with reminders of Diana. Westminster Abbey is where Diana's funeral was held in 1997; Kate included Lily of the Valley in her bouquet, just like Diana did; Bishop of London Richard Chartres, who spoke at Diana's memorial service, gave the sermon; and the first hymn, "Guide Me Thou, O Great Redeemer," is the same one that concluded Diana's funeral. Even Carole Middleton paid homage to the late royal by wearing Catherine Walker, Diana's favorite designer, on the day.

HARRY'S TRIP TO BRAZIL
Years may have passed, but the princes clearly still feel their mother's loss intensely. Last year, on a trip to Brazil, Prince Harry was nearly brought to tears while speaking with two young orphans who had also lost their mother.

Even with six or more slots to fill, there's still stiff competition when it comes to selecting royal godparents. Seven godparents were named for Prince George back in 2013, ranging from cousins to close friends of his parents. But despite the many options, William and Kate made a clear effort to choose someone dear to Diana's heart – Julia Samuel, a close friend of the Princess of Wales from 1987 until her death.

WILLIAM'S INVOLVEMENT WITH THE ROYAL MARSDEN
Both William and Harry are involved with many philanthropic organizations, and in many cases, have worked with causes Diana championed. Since 2007, Prince William has served as president of the Royal Marsden Hospital Trust, a position his mother held from 1989 until her death. Just as she did in 1996, William observed a procedure during a November 2013 visit.

HARRY'S WORK IN ANGOLA
In 2013, Harry followed in his mother's footsteps when he visited Angola, where his mom famously crusaded against the use of land mines, with the same charitable organization she did back in 1997. Here, he shakes the hand of Eufrafina, a 3-year-old girl whose mother met Diana 16 years prior.

GEORGE'S TRIP DOWN UNDER
Like Diana, William and Kate have already proven themselves to be modern-minded when it comes to raising their two children. So it's only fitting that, just as Diana and Charles did with William nine months after his birth, William and Kate brought Prince George on their own tour to New Zealand and Australia. In royal generations past, parents would leave their young children at home in the care of nannies instead.

Defying those who said that his mother's name wouldn't make an appearance in his daughter's many monikers, William gave Princess Charlotte Diana as her second middle name, a sweet and sentimental way of showing just how much the memory of his mother still means to him.

Another way the couple paid homage to William's late mother was when they christened their daughter at St. Mary Magdalene church in Sandringham, the same location where Diana was christened in 1961. Will and Kate also selected one of Diana's favorite photographers, Mario Testino, to take Charlotte's christening portraits.
As Diana's ex-bodyguard Ken Wharfe told PEOPLE in July, "William is keen to subtly keep [Diana's] legend alive."
"There are more references being made to Diana than there ever have been. This is a silent reference, if you like," he said of the christening location.

THE HALO TRUST
Both William and Harry have honored their late mother's memory by taking up the charities and causes that she championed. In 2013, Harry became a patron of the HALO Trust, an organization that clears landmines and the same organization that Diana famously partnered with in 1997. That year, Di's walk through a partially cleared landmine field in Angola made headlines around the world. Harry also took a landmine walk in Mozambique in 2010. Di's youngest son also met with Sen. John McCain to tour a Hale exhibit in Washington D.C. in 2013.
