Prince Harry married Meghan Markle in a ceremony that proved a fitting mix of the traditional and the unconventional, merging British tradition with American music and accents.
The Prince and his beaming bride exchanged vows in front of 600 guests in St George's Chapel at Windsor Castle.
But the BBC estimated the global audience would reach as many as 1.9 billion people.
This is how the world's media reacted to the royal wedding.

How America watched the wedding
Martin Luther King's daughter expressed her delight at the use of the civil rights activist's words in the royal wedding ceremony on Saturday.
Bernice King tweeted: "Your life, teachings and words still matter so much, Daddy. Congrats, Harry and Meghan".
More than 100 pupils turned out at Immaculate Heart High School in Los Angeles, Meghan Markle’s former school, to watch her marriage to Prince Harry.
There was a collective gasp in the auditorium at 4am local time, as they got their first glimpse of the bride.
Many of the girls attended the watch party with their parents. Annemarie Sauer Hale, whose daughter Michaela attends the school, was a little surprised by the dress.
“It was a little more conservative than I expected but she looked radiant,” she said. “And then the tiara that the queen let her borrow and the veil that went on for days. It was lovely, it was beautiful.”
Mother Carol Dance said the school fosters a strong sense of sisterhood and independence.
“They make empowered women here, it’s really nice to see a woman of strength being able to use her position to further her own causes. And it’s obvious that her husband is really charmed by that power too,” she said.
My very best wishes to Prince Harry and Meghan Markle on their wedding day. To all of those joining the national celebration with street parties and other events, have a wonderful day. #RoyalWedding— Theresa May (@theresa_may) May 19, 2018
“I think it’s a good step forward and globalisation of the world and this kind of ‘one love’ feeling which they talked about in the sermon,” Mother Stacey Johnson said.
The young girls are excited to watch Meghan, as she takes on her new role in Kensington Palace.
“She’s the only person of colour that’s in the entire royal family,” said Marigrace Carrasco, a 15-year-old student. “It’s crazy to think that you don’t have to fit in a certain box to make change in the world. She has all this global influence. I believe her a lot, I put my trust in her.”
Scores of well-wishers descended on the British-themed The Cat And Fiddle pub in Hollywood, celebrating Ms Markle's local connection.
The Chicago Tribune also found a local angle to the nuptials. It headlined its coverage: “Northwestern grad Meghan Markle marries Prince Harry in historic, star-studded ceremony at Windsor Castle.”
Harvey Young, Ms Markle's Drama professor at Chicago's Northwestern University, praised her choice of service.
"Meghan has written about her mother being misrepresented as a nanny. When Meghan talks about celebrating who she is as a woman it's to celebrate her blackness as well as her whiteness," he said
And speaking of diplomacy,Harry’s amazing bride Megan did an internship at @USEmbArgentina.You can apply for a @StateDept internship at https://t.co/15LFveTgcJ - sorry, internship doesn’t come with a #RoyalWedding! 2/2— Laura Kennedy (@AmbKennedy_ret) May 19, 2018
"That service is one that brings together everyone. I think you saw Black virtuosity on display, it's wonderful, extraordinary. Meghan should be proud of the ceremony."
Deborah Cohen, a history professor, added somewhat caustically: “It’s the longest-running reality show with an endless replenishing set of characters. Meghan represents another stage of it.”
Bill de Blasio, the New York Mayor tweeted his support for the young couple, alongside his wife:
Congrats, Meghan and Harry! Keep doing things your way. Britain will never be the same – and that's a good thing. https://t.co/4UYiOCaarN— Bill de Blasio (@NYCMayor) May 19, 2018
The Los Angeles Times was taken with the “pomp and pageantry” of the occasion and the personal aside from Prince Harry when he told his bride. “You look amazing.”
It was, the paper continued: “a tradition imbued ceremony” seen by millions worldwide.
“In an eclectic and evocative wedding service that blended the stylings of a gospel choir with a soprano's classical rendition of Handel, the two — gazing into one another's eyes and smiling — were pronounced man and wife in the gothic St. George's Chapel within the walls of Windsor Castle, a millennium-old seat of British royalty.”
The New York Post, one of the city’s tabloids, joyfully announced “Meghan Markle is now a royal”.
It continued: “The American ‘Suits’ actress, 36, tied the knot with Prince Harry in a wedding ceremony at London’s St. George’s chapel at Windsor Castle on Saturday attended by the royal family as well as celebrity pals including Oprah Winfrey, George and Amal Clooney, Serena Williams, James Corden and Priyanka Chopra.”
The New York Times said that Meghan Markle was in the span of an hour “transformed from a Ms. to Duchess.”
For the New York Daily News, the ceremony was “emotional.”
It added : “Prince Harry has officially settled down with American actress Meghan Markle after a touching ceremony held at St. George's Chapel on the Windsor Castle grounds.
Justin Trudeau, the Prime Minister of Canada, where Ms Markle lived for the past seven years while filming for the legal drama Suits, sent his congratulations to the royals.
He announced that the country would donate $50,000 to a children's charity to mark the occasion.
"To celebrate their union, Canada will donate 50,000 dollars to Jumpstart, a Canadian charity dedicated to making play and sports more accessible to children from disadvantaged backgrounds. Since 2005, Jumpstart has helped more than 1.6 million children of all abilities get out on the field and be part of a team.
"Sophie and I congratulate the newlyweds on behalf of the Government of Canada. We wish Their Royal Highnesses the Duke and Duchess of Sussex a lifetime of happiness, and all the best as they start this new chapter together. We look forward to welcoming them on a future visit to Canada," he said.
Nearly 5,600 miles away from Windsor, in South Africa, organisers of a party for up to 5,000 people arranged champagne, Union flag cupcakes and even bagpipe players.
Lize Millward, manager at 1Fox in Johannesburg, said: "People seem to like them because Harry is a really down-to-earth person, no chip on his shoulder, and Meghan, being an actress, people have seen her on TV and are interested in her."
In the Russian capital there was applause at St Andrew's Anglican Church as the Duke and Duchess of Sussex were declared husband and wife by the Archbishop of Canterbury, Justin Welby.
Rev Canon Malcolm Rogers, St Andrew's Chaplain, said around 200 people of different nationalities, roughly two thirds of them Russian, were at the church less than a mile from the Kremlin.
"The talk (by Rev Michael Curry) received applause - and people were a bit amused by how the congregation looked during the address," he said.
"In the current tensions, especially here in Moscow, it is a great thing to bring us together - perhaps an example of the power of love spoken about by the preacher."
