King Charles III has been crowned at London’s Westminster Abbey at a solemn Christian coronation steeped in 1,000 years of history and tradition, but adapted to reflect 21st-century Britain.

The build-up to the ceremony — the religious confirmation of Charles’s accession after the death of his mother Queen Elizabeth II last September — has been mostly celebratory.

Thousands of people turned central London red, white and blue on Saturday, with a sea of Union Jack flags lining the streets for the coronation of King Charles III.

But even before Charles, 74, and Queen Camilla, 75, left Buckingham Palace aboard the Diamond Jubilee State Coach for a rainy procession to the abbey, police arrested dozens of protesters using new powers rushed onto the statute book to crack down on direct action groups.

The anti-monarchy movement Republic — which wants an elected head of state — said six of its organisers were detained, while climate activists Just Stop Oil said 19 of its number were held.

CNN reports that Britain’s King Charles III has been crowned in a once-in-a-generation royal event that is being witnessed by hundreds of high-profile guests inside Westminster Abbey, as well as tens of thousands of well-wishers who have gathered in central London despite the rain.

The intricate coronation service followed a traditional template that has stayed much the same for more than 1,000 years.

The King took the Coronation Oath and became the first monarch to pray aloud at his coronation. In his prayer he asked to “be a blessing” to people “of every faith and conviction.”

The anointment, considered the most sacred part of the ceremony, took place behind a screen.

The King was presented with the coronation regalia, including the royal Robe and Stole, in what is known as the investiture part of the service.

He was then crowned with the 360-year-old St. Edward’s Crown, the most significant part of the coronation ceremony. After crowning the King, Welby declared: “God Save the King.”

Wearing the crown, the King was seated on the throne, after which the Archbishop of Canterbury invited the British public, as well as those from “other Realms,” for the first time, to recite a pledge of allegiance to the new monarch and his “heirs and successors.”

Ahead of the event, some parts of the British media and public interpreted the invitation as a command, reporting that people had been “asked” and “called” to swear allegiance to the King. In the face of such criticism, the Church of England revised the text of the liturgy so that members of the public would be given a choice between saying simply “God save King Charles” or reciting the full pledge of allegiance.

Once the King was crowned, his wife, Queen Camilla, was crowned in her own, shorter ceremony with Queen Mary’s Crown — marking the first time in recent history that a new crown wasn’t made specifically for this occasion — and presented with the Sceptre and Rod.

While Charles became King on the death of his mother, Queen Elizabeth II in September last year, the coronation is the formal crowning of the monarch and is a profoundly religious affair, reflecting the fact that aside from being head of state of the United Kingdom and 14 other countries, Charles is also the Supreme Governor of the Church of England.

However, it has been modernized in certain key ways. The archbishop acknowledged the multiple faiths observed in the UK during the ceremony, saying the Church of England “will seek to foster an environment in which people of all faiths may live freely.”

By early Saturday, the London Metropolitan Police Service announced that all viewing areas along the procession route were full and closed off to new arrivals.

The Met said ahead of time that Saturday would be the largest one-day policing operation in decades, with more than 11,500 officers on duty in London. Security around the event came into focus earlier this week when a man was arrested just outside Buckingham Palace after he allegedly threw suspected shotgun cartridges into the palace grounds.

The ceremony was expected to last two hours — about an hour shorter than Elizabeth II’s coronation in 1953. It began with the recognition and oath, followed by a reading from the Bible by UK Prime Minister Rishi Sunak and — in a coronation first — gospel music.

The congregation, while including some 2,300 people, is much smaller than it was in 1953 when temporary structures had to be erected within the abbey to accommodate the more than 8,000 people on the guest list.

The doors to the abbey opened just before 8 a.m. local time, with the first guests taking their seats a full three hours before the ceremony began.

Among the first people to arrive were singer Lionel Richie, musician Nick Cave, actresses Emma Thompson, Joanna Lumley and Judi Dench, composer Andrew Lloyd Webber, UK Labour Party leader Keir Starmer, and broadcaster Stephen Fry.

Top British officials, faith leaders and international representatives followed in their steps. They all took their seats in the vast church with more than an hour to go — reflecting the huge logistical challenges presented by an event attended by hundreds of VIPs.

All Sunak’s living predecessors as prime minister were there: Liz Truss, Boris Johnson, Theresa May, David Cameron, Gordon Brown, Tony Blair and John Major. Mayor of London Sadiq Khan, UK opposition leader Keir Starmer and Chancellor of the Exchequer Jeremy Hunt were also in attendance.

First Lady of the United States Jill Biden and the US Special Presidential Envoy for Climate John Kerry were there, as was the Chinese Vice President Han Zheng.

Canadian Prime Minister Justin Trudeau, French President Emmanuel Macron and numerous other world leaders were also present.

Last to arrive, just before the King and Queen, were the most senior members of King Charles’ family, his siblings and children, including Prince Harry who traveled to the UK from the US without his wife, Meghan, the Duchess of Sussex and their two young children. Saturday is also Prince Archie’s 4th birthday.

Music is playing a central part in the ceremony, and five new compositions have been commissioned for the main part of the service, including an anthem by Lloyd Webber, who is better known for West End musicals.

Charles’ consort Camilla will also be crowned in a shorter, simpler part of the ceremony.

Once done with the formalities, the newly crowned King and Queen will ride back in a much larger parade to Buckingham Palace, where they will be greeted by a royal salute.

The pomp and pageantry will conclude with the customary balcony appearance by the King and his family as they join the crowds below in watching a flypast of more than 60 aircraft.
