Millions of royal enthusiasts around the world were left delighted as the royal bonanza rumbled into Westminster Abbey.
On an emotional and happy day, King Charles III and Queen Camilla were properly sworn in.
From Prince Louis’ pranks to the coronation of our new queen, the amazing spectacle was not without its highlights.
We look back at some of the most memorable moments from a truly historic day.
1. King Charles and Queen Camilla’s coronation
According to Historic Royal Palaces, Charles was crowned with the St. Edward’s crown, which was also used at his mother Queen Elizabeth II’s Coronation.
Camilla was crowned with Queen Mary’s Crown, which was designed in 1911 for Queen Mary, King George V’s wife.
The Queen made history by becoming the first consort in modern times to wear the crown rather than a new one, an obvious gesture to encourage sustainability.
Camilla is thought to have had the crown personalised to suit her unique taste while also paying homage to Queen Elizabeth II.
2. Prince George plays a key role
As one of the King’s Pages of Honour, the Prince and Princess of Wales’ eldest child made his solo debut at a big occasion.
The nine-year-old is second in line to the throne behind his father, Prince Charles, and he rose to the occasion when Charles and the Queen were crowned on Saturday.
3. Prince Harry has rejoined the Royal Family.
The Duke of Sussex appeared in public with his royal counterparts for the first time since a number of devastating allegations surfaced in his recent memoir, Spare.
While it was only a brief visit, the Duke was seen entering the abbey with his cousin, Princess Beatrice, before smiling and waving to some familiar friends.
Harry left quickly, returning to the United States within 24 hours after his father’s coronation.
4. Prince Louis steals the show
Prince Louis drew notice once more as he arrived at Westminster Abbey with his brothers and parents for his grandfather’s coronation.
Several yawns were let out by the little monarch throughout the momentous ceremony, and she briefly left the church before returning for the national song.
As they sat before the high altar, he used the opportunity to point out interesting things to his sister, Charlotte.
As the service drew to a close, the royal children sang God Save The King as their grandfather walked past.
5. The Prince of Wales enjoys a touching moment with his father.
In a break from custom, the King and royal of Wales shared a moving moment as William paid homage, the only blood royal to do so.
Throughout the honour, William appeared to avoid making eye contact with his father.
He then kissed Charles on the cheek, and the King was seen speaking to his eldest son.
6. Penny Mordaunt plays an important role.
Penny Mordaunt was complimented for her behaviour during the King’s coronation ceremony, during which she held ceremonial swords for over an hour.
As Lord President of the Council, she was in charge of carrying The Sword of State and presenting The Jewelled Sword of Offering to the King for the first time by a woman.
She held and carried the pieces for the majority of the service, dressed in a custom-made teal costume with a matching cape and headdress with gold feather embroidery.
7. The royals ascend the balcony.
Charles and Camilla came out into the rain at 2.25pm, accompanied by family members including the Prince and Princess of Wales, Prince George, Princess Charlotte, and Prince Louis, the Duke and Duchess of Edinburgh, and the Princess Royal.
When the royals came on the balcony, celebrations erupted, and screams of “God save the King” could be heard.
8. The crowds brave the rain.
The rain did not dampen the joy of the people that lined the streets of London to catch a glimpse of the new King.
Some had gathered in the early hours of the morning along the 1.42 mile processional route between Westminster Abbey and Buckingham Palace, hoping for a front-row seat when the newly-crowned monarch appeared.
9. Protester arrests spark outrage.
Around the coronation, 52 persons were arrested for affray, public order offences, breach of the peace, and conspiracy to cause a public nuisance, according to the Metropolitan Police.
10. Scaled-back flypast still goes down a treat
More than 60 aircraft from the Royal Navy, British Army, and RAF were scheduled to take part in the flypast, but only helicopters and the Red Arrows flew during the two-and-a-half-minute spectacle.
11. Chinese vice-president among dignitaries
Chinese Vice President Han Zheng, who presided over a crackdown on civil rights in Hong Kong, is among the dignitaries invited to the coronation at Westminster Abbey.
Because of his function in the former British colony, the presence of Beijing’s representative is highly contentious, but the UK Government has made it plain that it wishes to retain interaction with the Asian powerhouse despite political differences.
12. Prince Andrew wears Garter robes at the ceremony.
The Duke of York wore his Garter robes at the King’s coronation, indicating a shift in the royal family’s attitude towards him.
Andrew, who stood down from royal duties following a contentious Newsnight interview and a backlash over his relationship with paedophile millionaire Jeffrey Epstein, wore the formal robes to the service at Westminster Abbey on Saturday.
