What to know about King Charles III, Britain's new monarch
London — With passing of Queen Elizabeth II, her first son, 73-year-old Charles, ascended the throne to officially become King Charles III. The new king had been the Prince of Wales — the title reserved for future British kings-in-waiting — for longer than anyone else in the history of the United Kingdom's monarchy.
"There is no way of getting around it, he is not in the first flush of youth," said CBS News royal contributor Julian Payne, who served as press secretary to then-Prince Charles. "What we will see instead of that is more than 50 years of experience on the world stage."
Payne said Charles would likely take the same approach to his role as king as his mother took to being queen.
"He, like his mother, takes the view that this is about duty and service," Payne said. "You do your duty. You provide the service to the nation when you're asked to do it. You don't seek it out, you don't try and get hold of it, but when it comes to you, you take on that role, and you try and do it to the best of your ability."
Charles' sister, Princess Anne, echoed that sentiment in an interview with the Canadian public broadcaster, CBC, just days before King Charles' official coronation ceremony at London's ancient Westminster Abbey.
"You know what you're getting, because he's been practicing for a bit, and I don't think he'll change," Anne said. "He is committed to... his own level of service and that will remain true."
First modern heir to the throne
In many ways, Charles has been the first modern heir to the British throne: He was sent off to school rather than being tutored privately at the palace, and after that he went on to earn a Bachelor of Arts degree at Cambridge.
The young Charles then served in both the Royal Air Force and the Royal Navy, being deployed on several warships during the 1970s.
Charles, Princess Diana, and Camilla
Charles' life in the public eye has been defined in many ways by the women with whom he has shared it. From early on, the boy-who-would-be-king had a duty to find a wife and produce future heirs.
Lady Diana Spencer at first seemed to be the perfect partner. He was 32, she was 20, and their wedding was a worldwide media spectacle. They had two sons, Princes William and Harry.
But it soon became obvious to the world that the royal couple wasn't happy together. As more and more photos showed them looking distant, the tabloids labeled them, "The Glums."
In their very public divorce drama, Prince Charles often unwittingly played the role of villain for a voracious tabloid press.
Asked post-split whether she thought Charles' long-time confidant Camilla Parker Bowles had been a factor in the breakdown of her relationship, Diana said: "There were three of us in this marriage, so it was a bit crowded."
When Princess Diana was killed in a Paris car crash in 1997, Charles' public image was so tarnished that many wondered if he could ever become king at all. It took years of being seen as the dedicated father to his two grieving sons for him to emerge from under the cloud.
But he did emerge, and eventually went on to marry Camilla in 2005 in the first non-religious, civil ceremony ever for a British royal in England.
Early in 2022, Queen Elizabeth II — clearly wanting no doubt to linger over her intentions — said that when Charles did become king, it was her "sincere wish that, when that time comes, Camilla will be known as Queen Consort as she continues her own loyal service" to Britain.
Charles said in a statement that he and Camilla were "deeply conscious of the honor represented by my mother's wish."
Invitations to the May 6 coronation, when both she and the king will be formally crowned, revealed that Camilla will drop the "consort" from her title after the occasion and be known thereafter simply as Queen Camilla.
A prince's "bonkers" pursuits
Once his life partner and future heirs were determined, Prince Charles concentrated his efforts on the various charities and other causes that he's supported – not all of them hugely popular initiatives in their day.
"I suppose I have spent most of my life trying to propose and initiate things that very few people could see the point of, or, frankly, thought were plain bonkers," he said in 2016. "Perhaps some of them are now beginning to recognize a spot of pioneering in all this apparent madness?"
The quip was an arguably permissible humblebrag by a royal who was ahead of many in embracing concepts such as organic farming, nature conservancy and the urgency of confronting climate change.
As Prince of Wales, Charles continued to be a passionate advocate through his charity work for everything from environmental conservation to community empowerment.
"I find myself born into this particular position," he once told an interviewer. "I'm determined to make the most of it and do whatever I can to help and, I hope, leave things behind a little bit better than I found them."
Charles and the presidents
King Charles is no stranger to the corridors of power on the other side of the Atlantic. He's visited Washington at least 20 times and has met every American president since Jimmy Carter.
He met President Biden in November 2021 at the COP26 climate conference in Scotland. Mr. Biden praised the then-prince for his leadership on environmental matters and reportedly told him: "We need you badly… and I'm not just saying that," crediting Charles for having got "the whole thing going."
During former President Donald Trump's state visit to the U.K. in 2019, Charles was scheduled to sit down for about 15 minutes with the American leader, but they ended up talking for an hour and a half.
Trump later said Charles "did most of the talking," but he described the royal as "a very good person" who was "really into climate change."
"What moved me is his passion for future generations," said Trump. "He wants to make sure future generations have climate that is good climate, as opposed to a disaster, and I agree."
In 2015, Charles met then-President Barack Obama for the second time during a three-day visit to the U.S. In the Oval Office, Obama commented that the American people were "quite fond of the royal family," and even suggested they "like them much better than they like their own politicians."
"I don't believe that," Charles replied.
