Following the sad news that Queen Elizabeth II has passed away at the age of 96, several members of the Royal Family - including the newly appointed King Charles III - have been taking part in royal engagements which have also involved meeting members of the public.
During these meetings, it's not unusual for royals to shake hands and chat with those who have lined up to greet them, but this routine didn't exist before the reign of Her Majesty. The practice of greeting members of the public, known as a "walkabout", was popularised by the Queen over 50 years ago, and it has since changed the way all members of the Royal Family interact with those who travel to see them.

Before the Queen's decision to buck royal tradition, audiences gathered to see the royals would only be able to catch a glimpse of them as they drove by in cars, but that all changed during a tour of Australia and New Zealand in 1970.
According to the 2018 documentary Queen of the World, the monarch - who was travelling with her husband Prince Philip and daughter Princess Anne at the time - said she wanted to meet a greater number of people and not just officials and dignitaries, and so the walkabout was born.
In the documentary, the narrator explained: "In the 1970s, the Queen decided to shake things up. She wanted to say hello to the crowds - and the walkabout was born."
And Anne, the Princess Royal, also spoke about the historic change in the documentary, as she said royals had never greeted the public before because it was deemed impossible to spend enough time with everyone.
She said: "We never shook hands. The theory was, you couldn't shake hands with everybody, so don't start."
The 72-year-old royal still isn't a fan of shaking hands though, as she added: "So I kind of stick with that, but I noticed others don't. It's not for me to say that it's wrong, but I think the initial concept was that it was patently absurd to start shaking hands. And it seems to me that it’s become a shaking hands exercise rather than a walkabout if you see what I mean."
There are some royals, however, who have fully embraced the walkabout and love nothing more than meeting members of the public - so much so that they're even teased for it.
In a 2016 documentary honouring the Queen's birthday, Kate Middleton - who is now the Princess of Wales - said: "There's a real art to walkabouts, everybody teases me in the family that I spend far too long chatting. I still have to learn a little bit more and pick up a few more tips, I suppose."
Walkabouts aren't the only thing the Queen changed in her legendary reign either, as she also made a significant change to a royal law that shook up the line of succession to benefit Prince William's children.
Ahead of the birth of William and Kate's first child, the Queen issued the Succession of the Crown Act, which updated discriminatory royal laws and meant that their child would have an equal right to the throne regardless of their gender.
As a boy, first-born Prince George's place as third - and now second - in line to the throne did not change, but the Queen's rule meant that the couple's daughter, Princess Charlotte, kept her place and was not bumped down when their third child, Prince Louis, arrived.
