King Charles III's coronation: The biggest moments of the historic event

As Charles was crowned king, ABC News royal contributors weighed in on the moment.

Robert Jobson said he was feeling "deep pride in my country and the royal family and the clergy."

"Particularly a bit of relief for the king because I thought when the archbishop was trying to get that crown on his head, he was trying a little too hard," Jobson added, with a laugh.

Victoria Murphy commented on how the "mood really shifted."

"It was very solemn, it was quite tense, it felt very serious and then suddenly, it actually feels quite joyous now," Murphy said. "It feels like a moment of celebration."

Sir Peter Westmacott, who previously served as Charles' secretary, said he also felt "a sense of great pride" and is "delighted for my old boss."

"It's a wonderful moment of pageantry and the mixture of humility and service," Westmacott added, "but also the crowning of a monarch in a way that no other country in this world still does or indeed knows how to do as we do."

Ailsa Anderson, who previously served as press secretary to Charles' late mother, Queen Elizabeth II, described feeling "rather emotional about it all."

"However you prepare for something like this, to actually see it has made me swell with pride but also emotional and also proud of my former boss, the Archbishop of Canterbury, who has been faultless in this service," Anderson said. "I think this service is pretty stupendous."

Kristina Kyriacou, who previously served as the communications secretary to Charles and Camilla, said she was "absolutely overjoyed."

"I couldn't be happier. I feel very, very emotional," she added. "This is a king who has worked every second and every hour of the day for the past 60 years. You know, since his teens, he has absolutely worked in public service serving his mother, serving the nation and the commonwealth -- and he deserves this. And I hope everyone understands all the good that he has done and all the causes that he has championed."

Charles and Camilla removed the St Edwards Crown and St. Mary’s Crown, respectively, before taking their seats at the Chairs of Estate and receiving communion.

The bread and wine for the communion is consecrated with the same wording from the Book of Common Prayer as was used at the queen’s coronation in 1953.

Camilla’s crowning moment is here as she is anointed on the head by the archbishop, and presented with the queen consort’s ring.

Camilla is crowned with the Queen Mary’s Crown, marking the first time a new crown was not created for a queen consort.

The Queen Mary Crown was redesigned though for Camilla, including the removal of the replica of the controversial Koh-i-Noor diamond.

Camilla's crown features the Cullinan III, IV and V diamonds, a tribute to Elizabeth, who counted the diamonds as part of her personal jewelry collection.

As Camilla is enthroned, the choir is singing “Make a Joyful Noise,” a new anthem composed by Andrew Lloyd Webber for the coronation.

William pays homage to his father on behalf of the royal family, following an homage from the Archbishop of Canterbury on behalf of the Bishops of the Church of England.

In a coronation first, members of the public are invited to pay homage to Charles too, led by the archbishop.

The public homage sparked controversy when plans for it were first revealed, with critics saying they should not have to pledge allegiance to the king. The archbishop responded to the controversy by telling the BBC the oath is "an invitation; it's not a command.”
Charles' younger son Harry was seen in the congregation paying homage to his father.
