Prince William and Kate Middleton were on Friday pronounced man and wife at the majestic Westminster Abbey where the couple exchanged vows in the presence of some 1,900 guests, while millions of people around the world watched the ceremony live on TV.
29-year-old Middleton wore an ivory and lace gown designed by Sarah Burton at Alexander McQueen, while the Prince, 28, was attired in the red tunic of an Irish Guards Colonel - his most senior honorary appointment.
Prince William, the second in line to the British throne, has been given the title of the Duke of Cambridge by the Queen, and Middleton has become Her Royal Highness the Duchess of Cambridge on their marriage.
The Prince has also become the Earl of Strathearn and Baron Carrickfergus, which means Middleton will become the Countess of Strathearn and Baroness Carrickfergus.
The couple were pronounced man and wife by the Archbishop of Canterbury Rowan Williams.
William and Kate had written their own prayer, "God our Father, we thank you for our families; for the love that we share and for the joy of our marriage".
Hundreds of thousands of people converged in London from all over the world for the royal wedding.
Thousands of street parties have been planned across Britain to celebrate the royal wedding.
Among the hundreds of guests at Westminster Abbey were soccer star David Beckham and his 'Spice Girl' wife Victoria.
Chelsy Davy, Prince Harry's on-again-off-again girlfriend, was also present.
US President Barack Obama was not on the guest list.
Britain's former prime ministers Tony Blair and Gordon Brown were also not invited.
