Members of the Royal Family gathered on the Buckingham Palace balcony after the King's coronation for what is now a famous photograph at state occasions.
There were marked absences of some members of the family compared to previous occasions, suggesting that Charles has pursued his plan to 'slim-down' the monarchy.
Royals including the Duke and Duchess of Edinburgh, Princess Anne, and Prince William and the Princess of Wales, were greeted by cheers as they emerged on to the balcony where they watched a flypast by the Red Arrows following the coronation at Westminster Abbey.
But other members of the family, including Princes Andrew and Harry - who are no longer working royals - were absent from the line-up.
Here are the people who appeared on the balcony with the newly-crowned King and his wife on the historic occasions.
1. The Duke of Edinburgh
The King's brother Edward, 59, was named the new Duke of Edinburgh in March, taking his late father's title on his 59th birthday.
Edward had taken over many of Prince Philip's responsibilities following his death in 2021, including the development of The Duke of Edinburgh's Award.
The title Duke of Edinburgh will be held by Edward for the rest of his life and will also remain the Earl of Forfar, but will use the former as it is the more senior title.
2. James the Earl of Wessex
James, 15, has become Earl of Wessex thanks to the ancient rules of primogeniture, which meant his older sister Louise missed out on the title.
The Royal Family ended the system of primogeniture - where titles and property do not go to the eldest child but to the eldest son - that had dictated the line of succession since 1701 in 2013 when the Succession to the Crown Act 2013 ruled that princes no longer take precedence over their sisters.
But it does not affect the situation of Prince Edward’s children as they were born before the law changed.
3. Lady Louise Windsor
Lady Louise, 19, and her brother took on a more prominent role following the death of the Queen where they joined their cousins, including the Prince of Wales and Duke of Sussex in a vigil at their grandmother’s coffin during the lying in state in Westminster Hall.
4. Vice Admiral Sir Tim Laurence
Princess Anne's husband, 68, has been a longstanding loyal member of the royal family and appeared by her side on the balcony. He is a retired Royal Navy officer and was equerry to Queen Elizabeth II from 1986 to 1989.
5. The Duchess of Edinburgh
Sophie, formerly the Countess of Wessex, is married to Prince Edward. The 58-year-old's role has become increasingly important within the Royal Family and she has publicly supported issues including helping victims of rape, sexual violence and exploitation in war, as well as promoting gender balance and equality in the workplace.
6. Princess Charlotte
As the second child of The Duke and Duchess of Cambridge, eight-year-old Princess Charlotte is third in line to the throne. Because of rules of succession, her children will also be higher up in line to the throne than Princess Anne’s children are.
7. Princess Anne, Princess Royal
Often referred to as the hardest-working member of the Royal Family, Princess Anne, 72, is the King's sister. She performed the role of 'Gold Stick in Waiting' during the coronation and rode on horseback behind his state coach as it returned to Buckingham Palace from Westminster Abbey.
8. Catherine, Princess of Wales
As wife of the next king and mother of the future heir, 41-year-old Kate is much-loved member of the Royal Family and plays a key role, carrying out duties alongside her husband and alone.
9. Prince Louis of Wales
As the youngest member of the family, five-year-old Louis enjoyed the coronation celebrations, providing entertainment for onlookers with some of his antics. Louis stole the show with his facial expressions as the Royal Family watched various helicopters and the Red Arrows sprouting plumes of blue, white and red smoke, over Buckingham Palace.
10. The Prince of Wales
Prince William, 40, is heir to the throne and pledged his commitment to father during the coronation ceremony. William has had a tempestuous time of late with rumours of a rift between him and brother Harry, but will undoubtedly be a key figure in the family as heir to the throne.
11. Lord Oliver Cholmondeley
Lord Oliver Cholmondeley, 13, whose father was a page for Queen Elizabeth, was one of the pages of honour for the coronation. He is reportedly a playmate of the king's grandchildren.
12. Prince George
Prince George, nine, is second in line to the throne and was a page of honour for the King's coronation. George was seen holding up a corner of the King’s robe as the royal party made its way into the church for the big occasion and sat behind the King in Westminster Abbey as Charles swore the coronation Oath. George went on his first royal tour when he was just nine months old, accompanying his parents on their official three-week tour of New Zealand and Australia, and has increasingly been making more and more public appearances in recent years as he gets older.
