Royal marriages to commoners have historically been uncommon, due to traditions of members of royal families, especially high-level ones, only marrying other persons considered to be royalty, sometimes with penalties for royals who married far below their rank, deemed morganatic marriage.
The Royal Marriages Act of 1772 also prohibited the marriage of royal family members to commoners (anyone not of noble blood). But now, as long as the Queen approves of the individual marrying into the family, then the marriage is considered valid, whether the person is of noble blood or not.
According to the royal marriage law of 1772 and the Succession to the Crown Act 2013, the first six people in the line of succession to the throne cannot marry without the consent of the reigning monarch.
10 weird things that British royals are forbidden from doing: from eating raw meat and signing autographs, to playing Monopoly and wearing fur – so how did Meghan Markle break with tradition …
The title of prince consort for the husband of a reigning queen is more common. The Crowns that adopted that protocol for a male royal consort based that on the title of King being historically higher than the Queen, so if there is a Ruling Queen, her husband could never be King.
A prince consort is the husband of a monarch who is not a monarch in his own right. In recognition of his status, a prince consort may be given a formal title, such as prince.
If Disney movies taught us anything, it's that when you marry a prince, you become a princess. So it may seem strange that when Kate Middleton and Meghan Markle married into the royal family, we were all expected to call them duchesses.
As an old tradition dictates, royal couples never share the same bed or bedroom, allowing them to move freely while asleep. It allows them much needed alone time after hours of being in the limelight.
There are no official rules forbidding public displays of affection, but the late Queen Elizabeth and Prince Philip set a precedent encouraging royals to keep touching to a minimum.
These include chocolate, coffee, and garlic — all ingredients that can destroy your breath. Charles' wife confirmed this during an episode of "MasterChef Australia." Camilla Parker Bowles said garlic was the one food she wouldn't want to see at a royal reception, due to Charles' distaste for it (via Twitter).
For most, a hug is a completely normal way to express affection, but not for royals when they're out and about on an official engagement. It's rare for a member of the Queen's family to embrace in public as they're technically working, but every now and then, the royals decide that rules are there to be broken.
The royal family is required to follow an extensive list of rules and pieces of royal protocol. However, King Charles and his family members also enjoy a number of royal perks. They're exempt from things like taxes and jury duty, and the king is allowed to break any law.
Divorce Is Allowed, but Not Encouraged
As anyone who watched The Crown already knows, the Queen eventually allowed (and actually encouraged) Prince Charles and Princess Diana to split up—but having the heir to the throne go through a public split wasn't exactly ideal.
Commoners aren't supposed to touch royals unless royals initiate contact. Celebrities like Joe Biden, Donald Trump, Allison Janney, and Ed Sheeran have slipped up. It's OK, though. Royals are forgiving and usually enjoy the change of pace.
Contrary to popular belief, there are no rules that require a prince to marry someone of royal or aristocratic blood, or even a British citizen (and in the case of Prince Charles and Camilla, Duchess of Cornwall, an incoming royal can even be divorced) — but religion is where it gets dicey.
Princess Madeleine and Christopher O'Neill
The only American man to marry into a royal family, (O'Neill has dual citizenship between the U.S. and the U.K.), he tied the knot with Princess Madeleine of Sweden in 2013.
The monarch isn't a fan of a deep bath either, she is said to bathe in “no more than seven inches of water”, according to royal author Brian Hoey for the Daily Mail. Seven inches is equivalent to 17.8 centimetres.
"Toilet"
If you're looking for a restroom in Buckingham Palace, ask for the loo or the lavatory.
Apparently, she heads to bed at 10.30pm each evening in order to get a good night's sleep. The bling is stunning, obviously. Regular exercise is also said to help with sleep and Kate leads an active lifestyle, often talking about how she loves to get outdoors – it's thought that she runs or walks every day.
Their home has four bedrooms, so it seems likely they now share a room, unless their children, George, Charlotte and Louis are bunking in together.
Their home may appear to be a cozy romantic love nest from the outside, but the couple actually sleeps in separate bedrooms.
A queen bed is the most popular mattress size amongst couples. It is perfect for couples with enough space for small movements during sleep.
Why isn't Kate called Princess? Even though Kate's mother-in-law was legendary 'Princess Diana', she is not a princess just because she married Prince William. To become a Princess, one has to be born into the Royal Family such as Prince William and Kate's daughter, Princess Charlotte of Cambridge.
There is also the case when a princess of blood royal marries a British prince. She also becomes a princess by marriage and will be addressed in the same way.
There is no law in the UK that prohibits a person from being crowned king or queen if they have been divorced. This may surprise some who know their history (or have watched The Crown) as people will point to Edward VIII who was forced to abdicate to marry Wallis Simpson, an American divorcée.
