In towns from Scotland to the South West, Britons marked the happy day by setting up trestle tables and bunting and cracking out the champagne for street parties.
Locals took the opportunity to meet their neighbours in the sunshine and tweeted photographs of impressive cakes and buffet meals, set up on red white and blue tables.
Some of the parties received funding from local councils.
Many events reenacted the wedding with small children playing bride and groom – although some formalised the pairing with a handshake rather than a traditional kiss.
Battersea Dogs and Cats Home, which has a Windsor branch a stone’s throw from the wedding location, also held a celebration for their residents – who are themselves hoping to discover their own forever friend in a human companion.
Among the VIPs was 10-year-old Staffordshire Bull Terrier Tyson, who wore his best Union Jack bow tie for the occasion and showed off his party tricks to guests. He is looking for a home to call his own.
Sussex residents were particularly excited at the news that Meghan and Harry will now become the Duke and Duchess of the county.
In Worthing, town crier Bob Smytherton hailed the couple’s new titles with a traditional announcement, while the town’s garden party was marked with a less conventional belly dancing performance. They hope the Duke and Duchess of Sussex will help attract more tourists to the area, and some said they were in tears watching the ceremony.
Some far-flung cities also had a reason to call the celebration their own.
In Los Angeles, Meghan’s home town, residents were thrilled that an American had become a Princess.
Many regarded the entry of a woman of colour into the Royal Family as a powerful indicator of a society becoming more inclusive, mobile and diverse.
Jasmine Chula, born and raised in LA, said: “As a woman of colour, to see another woman of colour in such a high position, it really means a lot, it’s genuinely inspiring.”
Students and teachers at Meghan’s old school, the Immaculate Heart in LA, said the new duchess was remembered as a bright and compassionate student.
They watched the ceremony on a live stream in the early hours of the morning, as did fans in Toronto.
In other locations, the time difference meant the wedding live stream was aired in time for an evening drinks session.
Many Australian monarchists celebrated the nuptials at the pub, toasting with some British ales.
In Thailand, The British Club in Bangkok roped in members to dress as the happy couple and made a convincing reenactment of the ceremony for jubilant crowds.
By early afternoon in the UK, the official public celebrations of the wedding had closed up. But street and pub parties are likely to continue into the evening, with an extra hour of pub opening due tonight.
