Prince Charles and Camilla, the Duchess of Cornwall, mark 15 years of marriage on Thursday.
But their story goes back much further than their 2005 wedding day.
Both of them were married to other people before they married one another, having been separated by circumstance as young adults.
Their first meeting and early years
Prince Charles first met Camilla Shand at a polo match in 1970.
Another version of their first meeting suggests they met at a party where Camilla told Charles: “My great-grandmother was the mistress of your great-great-grandfather. I feel we have something in common.”
Charles, already the Prince of Wales and of course the heir to the throne, entered the Royal Navy in 1971, a decision which put the brakes on their blossoming romance.
They dated for about six months, but Charles did not propose.
There are differing accounts of why the couple never made it down the aisle the first time. One is that their short relationship came in the middle of Camilla’s longer-term on and off relationship with Andrew Parker-Bowles, who became her first husband.
Other accounts suggest that Camilla was seen as unsuitable by some people in the Royal Family.

According to historian Bedall Smith, Camilla’s dating history was a strike against her, because the future king needed to marry someone “who at least appeared virginal”.
Their first marriages
Camilla Shand was the first to marry, tying the knot with Andrew Parker-Bowles in 1973.
According to some reports, pressure was mounting on them to get engaged, so Camilla’s father published the announcement in The Times to give them the hint.
It was a society event - the Queen Mother, Princess Anne, who once dated Andrew Parker-Bowles, and Princess Margaret all attended.
The couple stayed friends with Prince Charles, who they had both known before they married.
A few years on, and Charles met Lady Diana Spencer. She was just 16 when they met, and Charles was dating Diana’s older sister at the time. She later claimed credit for getting together.
Charles and Diana started dating in 1980 and announced their engagement the next year.
Charles, then 32, comes under fire for his response during their engagement interview to the question “are you in love?” He said: “Whatever love is.”
In July 1981 the young couple married in the royal wedding of the century at St Paul’s Cathedral.
Camilla attended their wedding, though it’s thought Diana didn’t want her to be there.
Charles and Diana had two children - William and Harry, and so did Camilla and Andrew - Tom, and Laura.
The affair begins
The Prince of Wales remained close to his former flame, and it’s reported that in 1986, they began an affair.
Diana is reported to have confronted Camilla in 1989, telling her: “Camilla, I would just like you to know that I know exactly what is going on between you and Charles. I wasn't born yesterday.”
She told of the confrontation in an interview with Andrew Morton.
In 1992, the affair emerged, as a recording of an intimate conversation between Charles and Camilla came out. The tapes were dubbed “Camillagate”.
John Major, then prime minister, confirmed the royal couple had separated in 1992.
In Morton’s book Diana: Her True Story, Diana referred to Camilla as “the Rottweiler” and Camilla called the princess “that ridiculous creature”.
Morton’s book also claimed Camilla accompanied Charles on a trip to Zimbabwe in 1980, in which she did research for him including “climbed onto the back of a buffalo to test its mettle before Charles’s scheduled ride. Thrown and badly gored, Parker Bowles was taken to the hospital—but not before canceling the Prince’s jaunt”.
Divorce and confession
Two years after then Prime Minister John Major confirms the royal separation, Charles admits adultery.
The prince did a televised interview with Jonathan Dimbleby in which he admitted that he had been having an affair with Camilla Parker Bowles for some time.
As he makes the confession, Diana steps out to the Vanity Fair party in what became known as the “revenge dress”.
Camilla and Andrew Parker Bowles divorced in January 1995, and he remarried soon afterward.
Later in 1995, Diana did her own televised interview, in which she also admits she was unfaithful in her marriage to Charles.
It’s then she utters the famous line: “There were three of us in the marriage, so it was a bit crowded.”
Charles and Diana finalised their divorce in 1996.
Diana was killed in a car accident in Paris in 1997.
A public relationship
A year after Diana’s death, Charles introduces William and Harry to Camilla. They kept the relationship out of the public eye for a while, but made appearances together on rare occasion.
One of those was Camilla’s sister’s birthday party at the Ritz Hotel in 1999. They arrived separately but left together.
According to Good Housekeeping, the progress Camilla makes by getting to know Charles’s sons is not matched with getting to know the Queen. The Monarch even reportedly turns down an invitation to Charles’ birthday because Camilla will be attending.
However they make it to the same event later in 2000, showing some improvement.
In 2001, the couple kiss in public for the first time - an important milestone in their relationship according to the BBC.
It was also the first time the prince played a supporting role to his girlfriend.
In 2003, Camilla officially moved into Charles’s London home, Clarence House.
Engagement and wedding
In 2005, Charles and Camilla announced their intention to marry. While the news may have shown Camilla had gained royal acceptance, there was a tough political decision ahead, particularly around the venue where they can marry.
A change in the law in 2002 meant they could remarry, though the Church of England is not supportive of second marriages where the spouse is still living. Wanting to avoid any more controversy, they opted for a civil ceremony in Windsor Guildhall.
The Queen and Prince Philip did not attend, but did go to the couple’s blessing in St George’s Chapel in Windsor Castle after the legal ceremony.
Life since then
Camilla has settled into royal life and quietly carved out a role for herself which has seen her win public approval after years of abuse.
She has known when to step forward and when to step back. In 2007, she opted not to attend the memorial for Diana, though saying she had been invited by Charles and the young princes.
Releasing a statement she said: “I accepted and wanted to support them, however, on reflection I believe my attendance could divert attention from the purpose of the occasion which is to focus on the life and service of Diana. I'm grateful to my husband, William, and Harry for supporting my decision.”
There have been questions over the years of what Camilla will be called when the Queen dies and Prince Charles accedes to the throne. Officially, she may be Queen or Princess consort, though it’s reported she is not keen to use the title, out of respect for Diana.
As the years have gone on, Camilla has been at Charles’s side for hundreds of royal engagements and family events, including the weddings of William to Kate and Harry to Meghan.
She has taken on her own patronages and roles too, particularly focussing on supporting victims of domestic abuse.
With their matching dry wit and humour and passion for the outdoors, Charles and Camilla have established themselves important and loved senior members of the Royal Family.
