THEN AND NOW: 22 images that demonstrate how royal life has evolved throughout time.

While some of the furniture has been swapped out, much of the room’s original decor remains.

There’s a hidden door disguised as a mirror and cabinet where the Queen enters to greet guests.

Ray Bellisario, known as “Britain’s first paparazzo,” was one of the first photographers to take unofficial and informal photographs of the royal family.

Bellisario started following the royals in the 1950s, and according to the Guardian, the royal family was not fans of the photographer.

Bellisario once tried to send the Queen a copy of his 1972 photography book “To Tread on Royal Toes,” and the Queen sent it back with a note that said: “Her Majesty does not accept the book and it is therefore being returned herewith.”

Now hundreds of photographers follow the royals’ every move.

Chris Jackson serves as the royal family’s photographer, but taking pictures of royals is a booming business.

The Church of England used to forbid marriage after divorce.

King Edward VIII caused a scandal when he signed his abdication papers after less than a year on the throne so that he could marry Wallis Simpson, an American divorcée.

The ban has since been lifted, paving the way for Prince Harry and Meghan Markle’s love story.

The Church of England has allowed marrying after divorce since 2002.

Queen Elizabeth’s wedding was broadcast by BBC Radio in 1947.

Elizabeth had to use clothing ration coupons to pay for her wedding dress after World War II.

Prince Harry and Meghan Markle’s royal wedding was broadcast by 15 different networks in the US alone.

Nielsen reported that 29.2 million people in the US watched Prince Harry and Meghan Markle’s wedding. There were also 6.9 million interactions on social media about the big day.

Not only are royal babies now delivered in hospitals, royals greet photographers outside hours after giving birth.

Kate Middleton’s stylist Natasha Archer met her at the hospital to help her get camera-ready following the birth of Prince Louis in 2018.

Royal births used to be announced via a bulletin posted on the gates of Buckingham Palace.

When Queen Elizabeth gave birth to Prince Andrew in 1960, the palace superintendent posted the bulletin as a crowd of 2,000 waited outside the gates for the news, according to Getty.

These days, birth announcements are posted on the official Kensington Palace Twitter as well as the palace gates.

According to the BBC, the post can only go up on social media after the formal announcement is displayed at Buckingham Palace.

Sons used to take precedence over daughters in the line of succession.

Succession to the throne is regulated by Parliament. The rule used to be that even if a daughter was older, boys were automatically higher in the line of succession.

The Succession to the Crown Act came into effect in 2015 and changed the male primogeniture rules.

Before this change, Prince William and Kate Middleton’s youngest son Prince Louis would have been ahead of his older sister Princess Charlotte in the line of succession simply because he’s male. Now, Princess Charlotte is third and Prince Louis is is fourth.

Royals used to put on Christmas pantomimes for the holidays.

In Queen Elizabeth’s youth, she and her sister Princess Margaret put on Christmas productions at Windsor Castle. In “Cinderella,” Queen Elizabeth played Prince Florizel and Princess Margaret played Cinderella. They produced the play for the benefit of the Royal Household Concert Wool Fund.

The Queen used to lead the Trooping the Colour parade on horseback.

Trooping the Colour celebrates the Queen’s official birthday in a tradition that goes back more than 260 years and involves over 1,400 parading soldiers, 200 horses, and 400 musicians marching from Buckingham Palace to Horse Guards Parade.

In recent years, she sat in a horse-drawn carriage instead.

Bowing or curtsying to royalty used to be necessary.

It was the proper greeting for members of the royal family, according to official royal protocol.

While it remains the traditional greeting, royals today often opt for a less formal approach.

According to the royal family’s official website, “There are no obligatory codes of behavior when meeting the Queen or a member of the Royal Family, but many people wish to observe the traditional forms.”

Royal expert Victoria Arbiter told Insider in 2017 that bowing or curtsying to royalty is not necessary.

“Certainly with the Queen because she’s the Queen and the older generation, you would most definitely want to curtsy,” she said. “The younger generations are a lot more relaxed when it comes to curtsying, so it’s certainly not a requirement, but it comes down to greeting someone with respect.”

Royals used to keep their distance from commoners.

They would wave, smile, and make pleasant conversation, but maintained a dignified distance.
