Charles III and Camilla were crowned at Westminster Abbey as King and Queen of the United Kingdom and 14 Commonwealth realms on Saturday.
It was Britain's first coronation in nearly 70 years and the first of a king since 1937.
Foreign leaders, dignitaries and other royal families attended the ceremony, while thousands lined the route to witness the coronation procession.
Meanwhile, anti-monarchy protesters gathered in London, as well as in Glasgow in Scotland and Cardiff in Wales, with signs and flags that read: "Abolish the Monarchy," and "Not my King."
London police said 52 people were arrested on suspicion of planning "disruption."
Here are some key headlines about the king's coronation:
Zelenskyy thanks 'true friends of Ukraine'
Ukrainian President Volodymyr Zelenskyy noted in his nightly online video address that his wife Olena Zelenska and Prime Minister Denys Shmyhal had attended the coronation in London.
"On behalf of the entire Ukrainian people, I congratulate Their Majesties, true friends of Ukraine," Zelenskyy said. He wished Charles a long and successful reign and said that the ceremony marked the beginning of a "new era" for Britain's monarchy.
"It was an honor for me to meet His Majesty personally in London," Zelenskyy said, recalling a visit in February. "I remember our conversation, I remember the sincere emotion for Ukraine and all Ukrainians."
Police say 52 arrests made
Londons Metropolitan police said 52 people were arrested in connection to anti-monarchy protests, saying they had information that some people would seek to deface public monuments with paint and disrupt "official movements."
"We absolutely understand public concern following the arrests we made this morning," Commander Karen Findlay of the London Metropolitan police said in a statement.
"Over the past 24 hours there has been a significant police operation after we received information protesters were determined to disrupt the Coronation procession."
A group campaigning to have the monarchy replaced said earlier on Saturday that protest organizers had been arrested by police.
"Organisers of the #NotMyKing protest have been arrested — police won't say for what," the group claimed in a Twitter post.
Anti-monarchy protesters want the monarchy replaced with an elected head of state and have been gathering at London's Trafalgar Square, although some have been seen brandishing yellow banners among the crowds lining The Mall.
"They've arrested six of our organisers and seized hundreds of placards, they won't tell us why they've arrested them or where they're being held," a Republic activist told AFP in London's Trafalgar Square.
Republic chief executive Graham Smith was one of those arrested before the group had a chance to wave placards declaring: "Not My King." Police did not confirm Smith's arrest.
DW's Birgit Maass said the organizers of the anti-monarchy protest had sent her a photo and said that two of their group have been arrested.
"They say their protest #NotMyKing was going to be peaceful and had been agreed with the police, and that they feel deprived of their democratic right," Maass said in a tweet.
Scholz, in Kenya, lauds Charles' environmental credentials
While Germany's head of state, President Frank-Walter Steinmeier, joined the pomp and pageantry in central London on Saturday, German Chancellor Olaf Scholz was on a visit to Kenya.
Visiting one of Africa's largest geothermal power plants, in a rare developing country that generates the majority of its electricity from renewable sources, Scholz praised the British monarch's longstanding advocacy for the environment and conservation issues, an area where he had been ahead of many politicians of his time.
"For me, it was and is very important that he is someone who is committed to close cooperation between the United Kingdom and the European Union and who also has his own very important agenda to advance climate protection," Scholz said. "That will also help us."
King Charles, Queen Camilla, watch flypast
The royal couple arrived at the Buckingham Palace balcony on Saturday afternoon, where they watched a Royal Air Force flypast.

Cloudy skies forced the Defense Ministry to scale back the flypast, which was scheduled to include rare vintage aircraft.
Defense Ministry scales down flypast due to weather
The British Defense Ministry announced shortly before the much-anticipated flypast that it would be scaled back due to "unsuitable" weather.
The flypast was originally set to consist of 60 aircraft, including the Battle of the Britain Memorial Flight — a collection of still-operable World War II-era fighters and bombers that do regular events in the UK, the Red Arrows, modern F-35s and Typhoons.
However, due to weather conditions, the Ministry of Defense scaled down the flypast to helicopters and the Royal Air Force aerobatic team The Red Arrows.
The flypast was due to last for two-and-a-half minutes.

German President Frank-Walter Steinmeier also congratulated the new king.
"For the great task that has now fallen to you, I wish you much strength and a lucky hand," he said on Twitter.

"On the eve of the historic coronation, we'd like to thank our British friends for your friendship. We are grateful for your unwavering support and partnership, especially in the past year!," the ministry said on Twitter.
US President Joe Biden hailed "the enduring friendship between the US and the UK" as a "source of strength for both our peoples."
"I am proud the First Lady is representing the United States for this historic occasion," said Biden, who missed Saturday's ceremony.

Days before the coronation of King Charles III, some South Africans called on the United Kingdom to return diamonds set in the crown jewels.
The world's largest clear-cut diamond was unearthed in 1905 and donated by the colonial government in South Africa to King Edward VII for his 66th birthday. It was cut up into several pieces, the largest of which is in the scepter the king will hold at Saturday's coronation.
